I have just recently purchased 1990 supra sunsport classic.
The motor starts and runs. Sounds ok but likes to start with choke on at first...Although, I dont trust anybody when it comes to boat motors. I like to do the maintenance and service myself if I can. This boat comes with a 454 PCM motor with about 850hrs on it and my questions are as follows

1) what problems should I be most concerned with this motor?
2) maintenance recommendations? Ie: known issues with specific part wear.
3) best place to find parts for the motor.

I can tell I will have a long relationship with this boat assuming everything in the motor checks out and I look foreward to keeping the forum updated with how it goes. I'll be posting pics of before and after once I get it all cleaned up
Thanks in advance
