Re: New Bowthruster unit - cost and in-stock?

Hi Colin,
Bad news indeed.
I would think that given you have no shaft, the if you put what remains of the bow thruster in the down position, the seal around the shaft and the foam seal on the motor side would probably keep most of the water out.
Good luck

Hi again Colin.if you didn't retrieve the thruster it would not be difficult to securely  plug the hole it goes through.

Hi sorry to hear of your troubles but as you rightly say it could have been much worse. 

I reckon that when pounding to windward there will be considerable pressure put on the seals with no plate there to take the impact. Going to windward in open ocean is not much fun at the best of times but with a niggling worry or a steady stream of water pouring in it could easily get out of hand. So you should do something. I made a similar passage in the 1990’s and Cap D’hombre on the north tip of Madagascar permanently blows at gale force. The southern Indian Ocean is a windy place, the trades tend to crank so even broad reaching the bow area will take a damn good hammering at times.

I would consider;

fitting a block of rubber/wood into the hole with silicon. The problem with wood is that it will swell and be difficult to extract.
filling the cavity with closed cell expanding foam.
How about, fitting plastic sheet to isolate the hole and then use expanding foam to fill the whole cavity, then cut it to shape and glass over the whole aperture area with epoxy and fibre glass. Then when you next haul out just grind it off  and pick out the foam and fit the new thruster, fill and prime and paint. You would need to get the bow out of the water to do the work. Perhaps going aground alongside somewhere and letting the tide drop a couple of feet to expose the area. 

I am sure that with a bit of lateral thinking you could blank off the aperture such that you would not need to worry about water ingress. Just make sure that you can extract and clean up what ever you do when you are ready to replace the thruster.

The above solution would be more watertight than the original!

You could also look at doing something on the inside but ………

Hello all, I just registered with this group because, after careful consideration of several bluewater yacht brands (we are past Pacific Seacraft owners), and time spent as crew on a Super Maramu, we have (almost) decided to purchase our own Amel.  Next week we are headed for Martinique to look at a few and I have a question for the group.

 

We will be looking at 2 Santorins and a SM.  

 

My question:  One of the Santorins, a 1991, was re-powered in 2011 with a "Midif MD 1760."  Looking this up I find it is a 50-hp turbocharged Mitsubishi-built engine, distributed by Midif in France.  I could find no reviews or discussion on this engine anywhere online.  Does anybody have any experience with or reliable info on this engine?  Reliability?  Is it suitable for a Santorin?  I assume all parts and support would need to come from the distributor in France.  

 

I will know more after a week on Martinique, but I am trying to be a well-informed shopper...

 

The other Santorin, a 1999, while "younger", has its original Volvo engine with 3300 hr (and original standing rigging), vs. the "older" Santorin which has the young Midif engine with 812 hr (and new standing rigging and seacocks). 

 

Don't want to post too much at once.  Thanks for any advice.

Mark,

 

Congratulations! This is really very good news for All SM owners that have electronic sensors on their bow thrusters.

 

If I still owned BeBe, I would buy one today for several reasons: 1.) The PCB on BeBe #387 was NOT protected by a fuse. 2.) Sooner or later, possibly every SM will need one of these and without Amel supporting it, we have few choices.

 

Maybe you should think about the Amel electronic chain counter as your next project.

Re: New member question

Thanks Craig.  That's reassuring to hear you say that about the 3300 hrs on the Volvo, because there are many other nice upgrades on the 1999 I am attracted to.  And sounds like the rigging replacement may not be as expensive as I imagined.   Anyway, I will keep an open mind next week.  No expectations--just gonna have a nice vacation on Martinique and, who knows, might end up with a boat...


Re: New member question

Craig Briggs
 

Very exciting, Paul, and early welcome to the DB.

Can't really say anything about the specific boats, of course, but, in general, 3300 on the Volvo should not be an issue if it's been well maintained.  You may well get two to three times that and if you do the same 150 hours a year that it's had that will last you maybe another 40 years!  My Perkins twin to that Volvo is at 7500 hours and shows no signs of needing replacement.  Plus the Volvo is naturally aspirated, which eliminates the turbo complexity. Then again Mitsubishi is a reputable brand, although I know nothing of the Midif.

The rigging on the original is coming up on 20 years so you'll want to evaluate the history. With only 150 hours on the engine it suggests to me the boat was lightly used (I average about 300 a year and only sail 6 months per year, which I'd consider maybe average usage.) If the boat was in the Caribbean all that time it may be due for a re-rig (about $5000 from Acmo in France and an easy DIY job). If it's been in a northern climate with light use, it may be fine.

It may come down to the overall condition, and the nod could go to the 8 years newer one. It'll be fun to learn what you discover.

Good luck shopping,
Craig SN#68 Sangaris

It runs more silent now and only uses ~0,5l diesel per hour compared to ~0.8l we used before.

Can someone tell me about if the OEM thru-hull fitting for the Airmar depth sensor is a 51mm housing?  


Mine is marked D800-P498 on the tag attached to the sensor wire, and "20-386-02" is printed on the top of the sensor.  I'm looking at the Airmar DX900+ and it says it will retrofit into the 51mm housings.  I cannot find any legacy product information on the Airmar website.


I remember a thread not too long ago on replacing the B&G Sonic Speed with an Airmar CS4500, and someone said they had to enlarge the hole to accomodate the new sensor.  The CS4500 also notes it will retrofit into most 51mm housings, that's why I'm concerned.


Thanks,

Craig, 

we have an Fischer Panda 4000i with a 1 cylinder kubota engine, 4kw.  Initial it had fixed RPM ~2900 but two years ago I upgraded it with a variable speed option (step motor that pushes the throttle depending on the load), now it turns between 2400 and 2900, depending on the load.  normally it runs with low speed because normal load is 1 to 2 kw, so it runs with ~2500. It runs more silent now and only uses ~0,5l diesel per hour compared to ~0.8l we used before.
