62t superjet

Hey guys! Newer to the standup world but I'm going all in on this build. This ski is one I want to try and keep for a long time, if not forever. So I want to build it right and have it be my work horse. Its a 1990 superjet that is stock currently except an aluminum handpole (factory length)...

problem need some solution I had an overheating on 701 engine, 81.5 piston , factory B pipe dual cooling system , TDR water box , and ADA head the problem started after 1hr riding and the cooling system was ok , once the engine got overheating I switched off and now the pressure on the rear...

I don't know if I'm not using the correct search terms, but I could find nothing on this topic. Purchased a donor Raider a while back, pulled the engine, purchased a JM735 kit, B Pipe, etc.. Always been curious about what people do with the "Mount Rubber" on the bottom of the engine... I like...
