So I bought a 1981 21 ft cuddy cabin and it came with a 15" x 17" prop. Worked fine but seemed rpms were pushing 5000 when WOT said 4600 so I put a 14.5" x 19" prop on it and it ran like shit. Still was saying my rpms were high. Any suggestions as to what size prop is best for bigger boats ?
Hi I have a 1981 cuddy cabin with 260hp OMC motor and noticed gear lube leaking just a little out of the check oil level plug after the first time i used it. Took it out twice since then and it ran great. It still seems to be leaking a little gear lube from that plug. Any advise would be greatly...
