Bought a 1988 js550 for $240 dollars that needs some love. The engine was full of water so i decided to throw in a 650 I have laying around. I plan to tear everything down and repaint and re-assemble everything. As of right now I need a 550/650 conversion plate, steering cable, am waterbox, 650 pipe and maybe a different pitch prop (unsure on what size works best). Will post pictures along the way. Thanks, Zach
