Hi Marco,

Are you still using the AutoProp H6 with the new engine?  If yes, did you have it modified in any way?

dears,

the TMD22 with the mechanical gearbox (2,8 reduction factor) and the autoprop h6 was probably  never reached in our 20 years of SM  more than 2500 2600 rpm ,

The TMD22 engine characteristic curve show that the 78 hp ( the max power) is obtained at 3500 - 4200 rpm  but at 2500 the curve show 40 hp and the boat has never reached more than 7.5 knots 

Now we have moved to the yanmar 110 cv,  the new version of the yanmar 100) with gearbox with 2.3 rduction factor   (midway betwenn the 1.97 of amel 54 with 110 volvo and  2.8 of the yanmar 100 )  that is  the new version  of the well known  Yanmar 100 cv  installed by Amel  after the TMD22. In Italy due to a severe restrictions of  omologation certificate we had also to afford the cost of new homologation certificate but we hare happy with this change . indeed the boat seems to go much better, it has a cruise speed of 8,5  at 2300 rpm over 3200rpm ( max engine regime)  and also in the manoeuvres she is more prompt than before . 

cheers and good wind .

This is question without a definitive answer. 

We also have the TMD22. When we bought our boat (about 4 years used), we could get almost 3,000 rpm at max throttle. Our local diesel guy suggested cruising at 80% of max, or 2,400. Our max started to lessen within about a year. 

Ever since then, we have usually not been able to max out at 3,000. Usually max is 2,400 to 2,600, so we cruise at 80% of that.

Issues affecting max cruise rpm include bottom, prop (even one barnacle can make a difference), turbo condition, and countless others. 

I suppose that, just like me, the Volvo has also lost a little mojo as it has aged.

Barry, I was reading this thread and saw your comment about the "Slap Silencer." You noted it was online, but where?
I have this problem with my 54, but mostly have become numb to the slapping in the aft cabin. The boat came with a very heavy canvas in a bag, and I suspect that is what it is for, but I have never tried it.
Can you provide more details about your solution? Is my bag carrying the right thing, and if so how do I use it?
Thanks,
Jamie

To,

Before you start chasing zebras, try these simple tests.

Does the engine start id you depress the valeo solenoid and someone tries to start the engine?

If you are able to start the engine then try the following.

Measure the voltage at the engine between the power + wire to the valeo solenoid and the battery ground when someone tries to start the engine.. IF you get 12.5 volts + then there is a problem either with the valeo solenoid or the yanmar black solenoid mounted next to the valeo solenoid.

 

If you do not get 12.5+ volts then there is a problem with the red wire from the panel. Look at the yanmar B panel wiring diagram.

 

The red wire is a wire going from the Yanmar engine panel to a 3 wire harness. The wire is Red but it might be spliced into a white wire.

Remove the Yanmar panel and look behind it for a solderless crimp connector joining the 2 wires.

It is about 1 foot from the panel down in the mess of wires. If you have that connection remove it and solder the wires together. That is the wire that both closes the valeo solenoid and starts the engine.

 

That wire runs to the smallest of the 3 harness connectors at the engine Starboard side possibly under the insulation. There is a red, blue, and white wire on the 3 wire connectors. Open it up and spray it with corrosion x. 

 

I would love to know what you find.

The valeo is just an expensive starter motor solenoid for 12 volt vehicles. . What makes it different is the back actuator button.

 

If you have an automobile starter solenoid make it is an isolated ground solenoid. If the negative wire is connected to the metal body of the solenoid it is not isolated ground and defeats the Amel bonding.

It could be an internal connection.  It is a great spare to have.

 

The 24 volt valeo solenoid if for the genoa furler mounted most forward port side forward cabin.

The Valeo 12 V solenoid is 160 euros and the Auto version is about $20- Thats a lot of money for a rubber button

Where are you located?

Ps do you have a switch mounted in a white plastic perforated box outboard of the engine stringer and forward of a Calpeda AC pump? It is for a high water alarm. If you have this switch please see if you can identify the maker or at least send me a photo with measurements.

somehow the top 1/2 of that switch disappeared on Kimberlite.

Tom,

 

In addition to the great advice from Eric, be sure to take a look at the stop solenoid. This is often overlooked when dealing with a start issue.

 

 

With best regards,

To,

Before you start chasing zebras, try these simple tests.

Does the engine start id you depress the valeo solenoid and someone tries to start the engine?

If you are able to start the engine then try the following.

Measure the voltage at the engine between the power + wire to the valeo solenoid and the battery ground when someone tries to start the engine.. IF you get 12.5 volts + then there is a problem either with the valeo solenoid or the yanmar black solenoid mounted next to the valeo solenoid.

 

If you do not get 12.5+ volts then there is a problem with the red wire from the panel. Look at the yanmar B panel wiring diagram.

 

The red wire is a wire going from the Yanmar engine panel to a 3 wire harness. The wire is Red but it might be spliced into a white wire.

Remove the Yanmar panel and look behind it for a solderless crimp connector joining the 2 wires.

It is about 1 foot from the panel down in the mess of wires. If you have that connection remove it and solder the wires together. That is the wire that both closes the valeo solenoid and starts the engine.

 

That wire runs to the smallest of the 3 harness connectors at the engine Starboard side possibly under the insulation. There is a red, blue, and white wire on the 3 wire connectors. Open it up and spray it with corrosion x. 

 

I would love to know what you find.

The valeo is just an expensive starter motor solenoid for 12 volt vehicles. . What makes it different is the back actuator button.

 

If you have an automobile starter solenoid make it is an isolated ground solenoid. If the negative wire is connected to the metal body of the solenoid it is not isolated ground and defeats the Amel bonding.

It could be an internal connection.  It is a great spare to have.

 

The 24 volt valeo solenoid if for the genoa furler mounted most forward port side forward cabin.

The Valeo 12 V solenoid is 160 euros and the Auto version is about $20- Thats a lot of money for a rubber button

Where are you located?

Ps do you have a switch mounted in a white plastic perforated box outboard of the engine stringer and forward of a Calpeda AC pump? It is for a high water alarm. If you have this switch please see if you can identify the maker or at least send me a photo with measurements.

somehow the top 1/2 of that switch disappeared on Kimberlite.

So, engine doesn't start intermittently. After corrosion x in the solenoid, cleaning contacts, problem re-emerges. Can start engine by pushing button but need to fix this. Broke out spares purchased across the years and noticed my spare solenoid is 24 volt (need a 12 volt). I have a Cole Hersee 12 volt solenoid (no button) but am not sure if the wiring relating to the "s" and "I" marked small terminals on the solenoid relative to the red and black wires on the existing valeo solenoid. Any thoughts ? Internet research suggests red to "I" but I'm not confident enough to do it. Of course will order correct solenoid when possible.
