Re: [Amel Yacht Owners] Re: Yanmar 75HP - Cannot go over 2300 RPM

As I stated above in this thread, I also have low engine RPM. It was 2500 RPM maximum when I bought my boat. I have 75 HP YANMAR with transmission 2.8:1 ratio. I contacted US Autoprop representative. He forward my question to the factory. See below their reply. I copied and pasted it below.
My boat is on the hard now. I plan to check torbo when boat is in the water. I will conduct some other tests. If I could not resolve the problem I will remove the prop and send it to US Autoprop representative for a pitch change.
