I have the tilt trim assembly without the motor from a 1989 force 50 that I'm going to convert to my 1989 force 35. The serial on the 50 is 507y9b. I've looked at some motors but havn't found anything before 1990 for the lower 35,40,50 force motors. It looks like it has 3 mounting bolts. I just need to know what motor to put on it. thanks
