It's a 1990 Rinker 236 cuddy cabin. Engine is a 454, but I'd like to figure out the horsepower if possible. Engine serial number is OC766088 and the drive serial number is OC843744. I know it's a Bravo 1, but does anyone know what the ratio would be based on that serial number?

Eddie, Mercruiser can probably help you if LaRea's website doesn't have the information. Mercury Marine 1-920-929-5000. Good Luck. MT

The serial number begins with a 0(zero) not an O. The boats.net site shows it as a 7.4L Bravo setup.

Eddie, if it's a 1990 stock 454 I'm going to say you have 330 hp. Al may respond to correct and as usual I'd certainly yield to his advice. MT
