Ya mar recommends running the engine full throttle 5 minutes every hour or 1 hour a day. The want you to heat things up to burn off carbon deposits.

So my engine is a Yanmar 2GM20F. I find the vibration "sweet spot" for motoring is about 2200 rpm. Sounds like I should be pushing it harder trying to find a sweet spot at a higher rpm? I can't recall what the tachometer range is on my boat. I've also had someone mention pushing the engine up to a high rpm before shutting it down for what reason I don't know. Lastly, I notice truckers never shut off their engines immediately after a highway haul. Should I idle my engine before shutting down after a long motor. Thanks for your thoughts.

I believe this to be a result of regulatory keeping the engine load as high as possible.

I had a moment yesterday to do the replacement with parts which I have had for some time. The rubber exhaust hose was stuck on and a considerable amount of wrestling was required to separate it from the riser. In the effort it went unnoticed that some of the rust blisters had broken away. Once I finally got it off and had a chance to inspect I found that the rust had opened up a dime sized hole. If this had let go unexpectedly I would have started blowing exhaust and water into my engine compartment. My "what would I have done" thoughts started rolling and I've decided that a tube of epoxy putty would have been my first effort at an emergency repair. https://drive.google.com/folderview?id=1aC6-4V8P3BufZhZsusYFmMlmHknk-Ftv Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD _______________________________________________ Thanks everyone for supporting this list with your contributions.
