I have a 1985 Bayliner Trophy Cuddy Cabin that I just purchased the previous owner installed a new engine in it. The numbers on the GM block is 10066036. Then I found another number stamped on the motor 04 i think that may be the year of production but not sure. it was stamped on the top rear of the motor. My question is how can I find out what starter needs to go into it. I have taken the old one out but it does not have any numbers on it.
