Greetings Petter powered C27 Owners:
My '73 C27 has a Petter AB1W - 6hp. Its slow and and hard to start - but works well once its underway if conditions are fairly reasonable.
I'm wondering about peoples' experiences with this engine.
Have you ever been in a position where this engine could not push your C27 against wind and waves?
Have you ever experienced abrupt high RPM (engine runaway)?
What's your cruising and top speed? RPM at these speeds?
Prop diameter and pitch?
Starting routine and/or tips?
I'm considering replacing this engine with a Yanmar 2GM to get more power. Talking with another sailer leads me to wonder if maybe some prop work might move me a bit in the same direction with much less work.
He said his engine (bigger engine, bigger boat) would sometimes seem to runaway (abrupt high RPM from prop cavatation, he thinks) when being pushed hard. He had the prop reworked (more pitch) and RPM dropped for a given speed, he could reverse better, and the engine no long ran away.
I'm thinking that if other people have had better experience with this engine that me, perhaps I should give this engine another chance. Any thoughts from other Petter AB1W owners?

Any suggestions on engine mounts for the Petter?
The engine mounts for my Petter diesel are probably going bad.
The PO allowed fuel to drip on the current rubber ones, and so they are
going bad.
The Petter manual recommends solid mounts. But I'm worried about that as
the engine vibrations will be transmitted to the hull more. I don't know
how the engine was mounted originally.
