You asked for opinions.....

With new solar, and lithium batteries the future of gensets has almost come to an end.  You can put 2KW of solar on deck with 900AH of LiFePO4 batteries (at 24V).  This would life better than getting a new GenSet.

Keep the genset though, you might use it about 50 hours per year, max, with the set up above.   And you might even get another 10 years of life out of that Onan.  Onan's are very good gensets!

I have just replaced the same motor and gear box. I sourced the replacement from Mauripro, at a good price and with excellent service.  The unit is heavy so be careful pulling it off.

Sorry did not mean to send that.

Bottom line is that I am sure you have found the problem. Carbon dust with oil leak to make it extra messy.

So far I am working with the motor in place. I have yet to learn if it can be removed from the winch without dismatling the whole mecanism. I live in hope.

Thanks for your input.

Hi Danny, 

The motor looks pretty much the same as the motor for the windlass on my 54. 

On my windlass I had a similar problem as you describe. The motor also got hot.

I removed it and stripped it down. It was clogged with carbon dust from the brushes. 

I then put it back and it runs perfectly.

I suggest you see if the motor itself gets hot,  if so it could be the same problem.

Danny,

These are so reliable that there is very little experience in troubleshooting and repair. I have no experience and few owners have very little.

I don't know how to help, other than to say most issues have been control issues and not motor and gearbox. Please let me know when you find a solution.

Hi Bill Yesterday the port sheet winch motor malfunctioned. When i tried to operate it  it would turn but in a few seconds slow to a stop as if it was overloaded.

The winch turns freely by hand and by winch handle so the problem is either in the motor or gearbox. Any suggestions. I have got under it and externally it looks fine. Do you know if its possible to separate the motor from the gearbox in situ. See photos attached

If you drop the motor and gear box be careful to keep it level as oil from the gear box can leak into the motor and then out and make a mess....been there!!

Thanks, all!  

I was not looking to install one, just get a feel for the setpoint.  A minimum setpoint of -200 mbar gauge (80 inches of water) tells me what I need to know.  That's a significantly higher vacuum setpoint than I expected.  I would have thought something like 20 instead of 200.

For our raw water system, (which is a lot simpler than a later model SM) the AC units quickly shut down on high pressure if there is insufficient water, the genset quickly shuts down on high exhaust temperature if it lacks water. Adding a high wet exhaust temperature alarm to the main drive engine will cover pretty much all the cases.
