Outboard engines 4 Stroke and 2 Stroke

Bill & Judy Rouse <yahoogroups@...>
 

FYI

Two months ago, we bought a new Honda 4 stroke 10hp outboard. It is really a great engine. However, because of the handle, it will not fit in a SM aft lazarette.

Our 15hp 2 stroke Mercury had lasted 13 years and was still working, but not as reliable as before. I had checked with other sailors about buying an exact replacement. All of these experts told me "no way...you can't buy them anymore."

The first marine shop I walked into in Trinidad had a brand new Mercury 15hp 2 stroke in the window and it is priced $1,000 less than the Honda. I am hoping to find a Honda lover. They are great engines and I will make them a great deal at 25% off.

And, if you are traveling to the Caribbean and Trinidad, I can tell you where to buy a Mercury 2 stroke at almost any horsepower.

Also check out the nesting dinghies.  They are hard dinks that come apart into two halves.  They are much better to row, can be sailed or powered with a small outboard.  I don't remember the name, but one that I looked at online would fit easily on the aft deck.

I suspect I know the answer to this already, but it's worth asking the group...

Has anybody found a rigid hull inflatable dinghy that when deflated/disassembled fits a Super Maramu's aft deck locker?

Hi Bill,
Agree with Steve that you won't find an adequate rib that will fit in your lazarette.  I have the 10.5 ft AB with fiberglass hull.  It is a very dry ride compared to other details blks I've had, but it is much too heavy, get the aluminum hull.  Also, like Steve and Liz, I carry mine on the foredeck when underway.  The biggest drawback is that the forward hatch can't be opened...but you probably wouldn't open it underway unless on a downwind run.  For long passages, I still carry it on the foredeck, but deflated.

Hi Bill, 

I don't think you are going to find a RIB of suitable size that will fit in the aft locker. We have an AB 9.5 aluminum which we are quite fond of. It is under 100#, which makes it fairly easy for the two of us to get it stowed on deck. We stow it fore and aft and deflated on the aft deck for long passages. Just Island hopping in the Caribbean it is normally upside down forward of the mast, and stays inflated. The Highfield aluminum 9.5 is another good choice, but is not quite as dry of a boat as the AB.

We bought a Highfield Ultra Light 260 this year. Aluminium hull. It fits on the front deck of our Santorin inflated or on the afternoon deck with the bow deflated or completely deflated it sits easily inside the grab rails.
Also we got a 2 stroke 9.8  outboard. It weighs the same as a 6hp 4 stroke which is the max recommended by Highfield  works fine.
I haven't attempted to stow it in the lazarette. My guess is the depth won't accommodate the width.

Hi Bill K,

We have the same RIB as Steve Davis… gives me a real pain in the knee when I play silly bugger and bounce off the wave tops at 30 knots.  

Just spent quite some dosh getting a knee refit… but the RIB is great if like us, you plan far horizons.  It is your daily driver.

We keep ours inflated on the fore deck (added some very solid tie downs) on passages and in the davits when just going coastal.

Boom track bolts

eamonn.washington@...
 

Hi

when I had the standing rigging replaced in April, which involved removing the 2 masts, I also requested that the masts and booms be treated and painted. My problem is that when they reinserted the outhaul tracks on the two booms they used new stainless steel bolts, since they lost/discarded the original aluminium bolts.  I am far away from the boat currently.  Could someone please tell me the specification of these bolts, or let me know where I can buy them?  Also how many are required?  About 32 I think?


Many Thanks

Re: Valve lash/clearance

Walter
 

Hi Mike,
Noa has a Yamar engine which is serviced different, but we had a Volvo TMD22 on our previous boat. The camshaft cover on the TMD serves as the upper part of the camshaft bearing. When you disassemble it to check the valve clearence, you will either need a special tool (three camshaft moutings which hold down the camshaft) made by Volvo or you find a machine shop/build them by yourself.
In case the clearance is outside the tolerance 0,2-0,4 inlet or 0,3-0,5 outlet, you need to readjust to 0,25-0,35 inlet and 0,35-0,45 outlet. If the clearence is inbetween the first tolerance, you don´t need to readjust.

Kind regards,
Walter (Noa, SM2K #436)


Re: Mizzen Roller Reefing

Derick Gates SM2K #400 Brava
 

Mohammed and Aty,

When my mizzen furler finally completely seized up, the sail was being unfurled, and the force of the winch handle is what unscrewed the shaft from the main housing.  Taking off the winch shaft from the main housing, if you can, does give you access to the gear box to grease the bevel gears.  To prevent the winch shaft from unscrewing inadvertently, I used blue locktite when I screwed it back in, having scrupulously cleaned all the screw threads beforehand.  If you are trying to take it apart you might try using an oil filter wrench strap.  It unscrews in the normal way, counter-clockwise.

If you are accumulating water in the gearbox, it is probably dripping down into the gearbox along the path of the foil.  Perhaps the drain holes in the bottom of you gearbox are plugged with old hard grease.  I did not try to take the main gearbox apart to further investigate how it is constructed.  

Good luck!

Re: [Amel Yacht Owners] Diesel fuel problems and additives

webercardio <webercardio@...>
 

Hi to the group,
Sludge in the fuel tank is caused by bacteria growth in the fuel which is caused by 7% Bio-diesel added to the fuel in Europe. Growth starts with the aging and water from condensation in your tank.
It is highly  recommended to ad antibacterial treatment. From the beginning I started with grotamar  -shipped by SVB.de for low cost of mailing. Liqui-molly has also now 2 products  ( one with extra treatment for the engine)
A polishing system for fuel and tank cleaning is offered from some some companies if you already have Sludge in your tank.
You will find some links on Google for Dieselpest, one pdf by mikrofiltertechnik

Betreff: Re: [Amel Yacht Owners] Diesel fuel problems and additives

 

Good morning hesitated to reply since I have limited knowledge fuel additive.

For my Diesel, I used to use only: Star Tron Diesel
Recently I decided to add Biobor JF based a Practical Sailor research.

For my (for outboard 2 Cycle) I use hammonds biobor eb gasoline treatment

Personally, I change (just did it 2 weeks ago) both the Racor and the fuel filter on the engine (and generator).
Compare to the overall cost of owning a vessel, I feel these are very cheap not to be changed and potentially take a risk, especially single handed and usually only motoring when entering/exiting a harbour or marina.
In my opinion, loosing an engine (due to bad fuel) just once in 10 years could potentially cost $1000s of dollars being pushed by the wind or current in other boats or rocks ashore, possible issues with insurances and so on, unnecessary stress, etc. I don’t think it is worth it.

When I fill up my diesel tanks, I fill up (5) 20 Liters Jerry cans then fill up my tank through a Baja filter, I do it for the entire tank.
2 weeks ago, I fill up my diesel and doing so directly still I filter through the Baja filter.
It definitely took a lot more time and the marina employee was very patient, I feel better doing so (again in the fear of loosing the engine).

Kent,
The following is my opinion(s) and some
facts:
Fact: Valve lash is the adjustment made to the
intake and exhaust valves on your diesel engines to ensure
that the valves open and close correctly.

Opinion: The valve lash should be adjusted on your
enginenand generator about every 1000 - 1200 hours of
operation. Incorrect valve adjustment (lash) will cause
unburnt fuel to enter the exhaust, causing some smoking and
leave a diesel stain on your hull.
Fact: Regarding your Racor filters, the filter
material will deteriorate with time.

Opinion: I change Racor filters at 400 combined hours, or 1
year, which ever comes first. I think you should change
those 5 year filter elements.
Opinion: When buying fuel, I like to pick a
very active fuel dock. I always run the first 20-40 liters
through a fuel filter/water separator funnel. If it is clean
with no water, then I put the fuel directly into the tank. I
have had only one occasion when I told the fuel dock to
forget about it, and paid for only the 30 or so liters.

Hello Aty &

Had a big
problem on previous boat… however, we had the tank sucked
out, fuel polished, changed all filters then no more
issue.
We’ve not had
any problem since installing the following upgrade on
Eleuthera: a pair of Racor 75900 with a 4 way valve.
 (1-2-both-off)
We
also use a bacteria killing agent at all times.  Also, for
those who use the low sulfur diesel… we do… (no choice
in most places) we add 1 liter
of 2 stroke oil to
each 500 liters.  Makes up some lubricity for the drier low
sulfur stuff though it contributes to extra hull cleaning
chore aft of the exhausts..

Hello

In talking to several different cruisers in the

I'd like hear others experiences and

Valve lash/clearance

Mike Ondra
 

Since this seems to be a hot topic, I checked in the Volvo TMD22 manual and this is what I found under Technical data:



Valve clearance, adjustment cold engine: Inlet 0.20-0.40mm : Outlet 0.30-0.50mm

Valve clearance, check cold engine: Inlet 0.25-0.35mm : Outlet 0.35-0.45mm



What is the meaning of the 2 sets of data, and does this imply that there is an acceptable range of values rather than a specific value?

Thanks, Craig, I believe that you are absolutely 100% correct.

Opinion: The consequences of out-of-adjustment "valve lash" are numerous, but the most common reason for diesel smudge on the side of the boat (which is what the original question was) is out of spec valve lash adjustment.

If I remember correctly, our 100hp and our Onan specs are around 1000 hours for adjustment.

Opinion: Regardless, I use 1000 hours on each of them. Unlike you, I believe that I have made very minor adjustments to the valve lash on at least one cylinder each time I have checked. I always do a complete check two times and a good mechanic will do the same.

Different engines have different characteristics.

Kent,

To add just a bit to Bill's reply, and not to be too picky, "valve lash" is not the adjustment, it is the actual gap between the rocker arm and the tip of the valve stem. Adjusting that distance if it is out of spec is a simple process and you'll adjust both the intake and exhaust valves. The effects of being out of spec are varied, and do not necessarily cause exhaust smoke, That is, don't think that the only sign of valve clearance being out of spec is smoking exhaust. That being said, this is not something to obsess about - I check mine every one or two thousand hours and they are always in spec. I'm sure the "book" recommends more often but that's to keeps the mechanics in business.

Kent,

The following is my opin ion(s) and some facts:

Fact: Valve lash is the adjustment made to the intake and exhaust valves on your diesel engines to ensure that the valves open and close correctly.
Opinion: The valve lash should be adjusted on your enginenand generator about every 1000 - 1200 hours of operation. Incorrect valve adjustment (lash) will cause unburnt fuel to enter the exhaust, causing some smoking and leave a diesel stain on your hull.

Fact: Regarding your Racor filters, the filter material will deteriorate with time.
Opinion: I change Racor filters at 400 combined hours, or 1 year, which ever comes first. I think you should change those 5 year filter elements.

Opinion: When buying fuel, I like to pick a very active fuel dock. I always run the first 20-40 liters through a fuel filter/water separator funnel. If it is clean with no water, then I put the fuel directly into the tank. I have had only one occasion when I told the fuel dock to forget about it, and paid for only the 30 or so liters.

Re: [Amel Yacht Owners] Diesel fuel smudge - cleaning hull

Bill & Judy Rouse <yahoogroups@...>
 

There is a cleaner available in the Caribbean and probably in the US and maybe Europe named H7.

H7 works very well, It is a very good degreaser/cleaner. Also, Citrus Clean works well. Both of these will also remove the wax. I think anything that will clean a diesel smudge will remove wax.

Thanks, Bill.  I'll do both the racors and have the lash checked.  I do have quite a bit of smudge on my hull.  Soapy water (Dawn dish soap) gets most of it, but if I wait too long it takes Soft Scrub.  The last time I washed it off, I put Maguire's paste wax on the hull between the exhaust and the aft end.  Very little smudge and holding its shine better than the rest of the hull.

This is not a smart-ass answer/remark.

When is the last time that the valve lash was adjusted on your engine and/or generator?  If the valve lash is not adjusted correctly, you will get a lot of exhaust staining on the hull.

Hello Aty & Mohammed,


Had a big problem on previous boat… however, we had the tank sucked out, fuel polished, changed all filters then no more issue.

We’ve not had any problem since installing the following upgrade on Eleuthera: a pair of Racor 75900 with a 4 way valve.  (1-2-both-off)

We also use a bacteria killing agent at all times.  Also, for those who use the low sulfur diesel… we do… (no choice in most places) we add 1 liter of 2 stroke oil to each 500 liters.  Makes up some lubricity for the drier low sulfur stuff though it contributes to extra hull cleaning chore aft of the exhausts..

I usually love to learn things, but how often do we do it... if it is every 1000 hour (10 years for me), plus I have to work 45 hours a week already...
Just like when my propeller was rebuild, I let the guy do it, next time due in 2000 hours or 10 years... but it is me.

I looked it up Alex.  It's the
distance between the valves and the rocker when the engine
is cold. If too small the valves don't seat properly
when the engine warms up. Beyond my pay grade right now, but
looks like something one could do with a little education
and proper tools.KentSM 243Kristy

Valve Lash is just another term for Valve Clearance. That is the distance from the Valve tip to the rocker. Google it for some good You-Tubeson how to adjust.. An easy and fun DIY project for a day in the engine room.
Cheers,

I looked it up Alex.  It's the distance between the valves and the rocker when the engine is cold. If too small the valves don't seat properly when the engine warms up. Beyond my pay grade right now, but looks like something one could do with a little education and proper tools.

Hello Aty &

Had a big
problem on previous boat… however, we had the tank sucked

We’ve not had
any problem since installing the following upgrade on
Eleuthera: a pair of Racor 75900 with a 4 way valve.
 (1-2-both-off)
We
also use a bacteria killing agent at all times.  Also, for
those who use the low sulfur diesel… we do… (no choice
in most places) we add 1 liter
of 2 stroke oil to
each 500 liters.  Makes up some lubricity for the drier low
sulfur stuff though it contributes to extra hull cleaning
chore aft of the exhausts..

Hello
everyone;
In talking to several different cruisers in the
med, it appears that some have had some serious issues with
bacterial or other types of growth in their diesel tanks
leading to the need for disposal and deep cleaning of the
fuel tanks.
I'd like hear others experiences and
solutions to the problem in order to avoid the
problem.
Thanks in advance

Re: [Amel Yacht Owners] Diesel fuel problems and additives

Craig Briggs
 

Kent,
To add just a bit to Bill's reply, and not to be too picky, "valve lash" is not the adjustment, it is the actual gap between the rocker arm and the tip of the valve stem.  Adjusting that distance if it is out of spec is a simple process and you'll adjust both the intake and exhaust valves. The effects of being out of spec are varied, and do not necessarily cause exhaust smoke, That is, don't think that the only sign of valve clearance being out of spec is smoking exhaust. That being said, this is not something to obsess about - I check mine every one or two thousand hours and they are always in spec. I'm sure the "book" recommends more often but that's to keeps the mechanics in business.
Cheers, Craig SN#68

Kent,

The following is my opinion(s) and some facts:

Fact: Valve lash is the adjustment made to the intake and exhaust valves on your diesel engines to ensure that the valves open and close correctly.
Opinion: The valve lash should be adjusted on your enginenand generator about every 1000 - 1200 hours of operation. Incorrect valve adjustment (lash) will cause unburnt fuel to enter the exhaust, causing some smoking and leave a diesel stain on your hull.

Fact: Regarding your Racor filters, the filter material will deteriorate with time.
Opinion: I change Racor filters at 400 combined hours, or 1 year, which ever comes first. I think you should change those 5 year filter elements.

Opinion: When buying fuel, I like to pick a very active fuel dock. I always run the first 20-40 liters through a fuel filter/water separator funnel. If it is clean with no water, then I put the fuel directly into the tank. I have had only one occasion when I told the fuel dock to forget about it, and paid for only the 30 or so liters.

Am I the only one here who's never heard of a valve lash?  What the heck is it?  Where is it? How is it adjusted?
Thanks
