Hot Rods – PWC / Jetski, including connecting rods, crank assemblies and thrust washers for Kawasaki 750, 900 ZXI and 1100 ZXI/STX, Sea-Doo 650 and 951 carbureted and DI, Yamaha GPR and Polaris 700, 900, 1050 and 1200 SLX engines. A watercraft engine is the hardest working two-stroke most people ever own. It runs at wide open throttle for minutes at a time with no load relief, it breathes damp air, and any water that gets past a seal goes straight into a rod bearing. Riders usually hear it first as a rumble at idle, then a ski that will not hold rpm on the top end. Hot Rods rods and cranks are built for that service with correct bearing packages and pressed assemblies that stay true under sustained load, so a rebuild lasts seasons instead of a single summer of hard riding. Doing the job properly with fresh thrust washers and matched components keeps the crank straight and stops the vibration that eats couplers and motor mounts. Parts are engine and model specific, and several of these fit only certain build years. Tell us the ski, year and engine and we will confirm the right part before you order.
