1993 fountain 35 speed
 

Just bought it 93 35 with 502 black motors spinning 25p mirages bone stock. How fast should it run. And what would be the next best performance thing to do. Thanks in advance

Run in the 70s. Get some seat time before modifying anything. Learn what is working on the boat, for example if your spinning max rpms with the props on it. Has complete maintenance been done to engine, drives, etc? When were the drives opened up and inspected last? Did you have a survey done, how are the stringers and the transom?

solid boat stringers and transom 1 new motor due to valve drop. planning on doing other this winter 500 hours on hull
