The diesel engine governors that I am familiar with mechanically limit the engine RPM to a preset level by reducing the throttle setting. If you are getting full revs. in neutral but not under load, I doubt that the governor is your problem. I am sure that you will get more specific help here from others with the possible causes of your low revs. Best of luck, James SV Sueño Maramu #220

James,
Thanks. The mystery continues, but we have a mechanic recommended here so we will see what he has to say about it.
Incidentally, there is a Volvo customer help line to which you can email an issue. I've done that. Silence so far.
Ian

Hi James, ( or anyone else )
If you are on board and have the same 75hp Volvo as I have, can you put on full revs in neutral and let me know what revs you reach ?
Thanks,
Ian and Judy, Pen Azen, SM 302, Athens

Sorry, I don’t have the same engine but hopefully someone else will answer that question for you. In general, if your engine is reaching your normal full throttle loaded rpm in neutral but you are 700 short under load of what is normal, either the load is higher than it used to be or the power output has dropped for some reason. You indicate that the prop is perfectly clean but perhaps it is not auto pitching properly for some reason? There has been a lot of discussion on the Auto-prop (which I do not have on my boat) on the forum that you could bring up by searching. Best of luck and I hope that you get more help with this problem, James SV Sueño Maramu #220

Thanks, James,
You may have seen my exchange with Bill. I think I may be getting somewhere.
We've always had a great experience with our Autoprop which is spinning freely. I have been amazed that it was able to work at all on a couple of occasions when we have left the boat in foul waters, once in Brasil and once in Spain. Both times you couldn't see any metal for mussels, but we still managed to limp along at 3-4 knots to a cleaning place. In Brasil, which has a lot of shark attacks that are kept out of the news, that meant spending too much time under the boat about 10 miles offshore. You would be amazed how quickly you can clean a prop.
I hope to post a happy ending to this story soon.

I am really glad to hear that you feel you are making progress with solving your engine problem. I think that we are certainly lucky to have knowledgeable and helpful people like Bill Kinney on this forum! He has taught me a lot and I always enjoy reading his posts. Do let me know when you cure the engine problem. My wife and I should be headed up the Adriatic in about 3 months so who knows maybe we will cross paths. It would certainly be interesting to hear more about your experiences in Brasil. Best, James SV Sueño Maramu #220 Arbatax, Sardinia
