We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".
3000 to 4000 rpms even in a large vessel is still not that big a deal as they are under constant and steady load. Providing the oil supply is kept constant and cool and the engines have a compression ratio that will not allow detonation. Marine engine manufactures use 4000-4400 rpms as the redline as that is where the engines produce a good balance of torque, fuel economy and oil and water tempature control and recommend the boat builder to gear and prop their boats accordingly.
