Hi Walter, your engine is indeed a 2GM20F. Max RPM is 3600 but only for short bursts, your cruising sweetspot will be 75 to 80% of your max RPM, so figure around 2700 to 2850 RPM.

Hi Allan
I'll start by saying hope you get this. You are right on with the sweet spot. I now have a Kiwi Feathering prop. It has lowered my sweet spot. Are you the wikipedia of C&C 30. Ha Ha Thanks

Hi I'm back again I've had 10 sail todate. I've have an asymmetrical spinaker. It came with my C&C mark ll and I have no idea how to rig it or sail with it. Is there some site or someone out there that can help. Thanks

Hi Walter,
I've never flown an asymetrical, best place to post this question is on the cncphotoalbum.com, you'll get many replies. Enjoying your new boat?
