Here are some areas of support to help keep your Sea Doo alive:
Rebuilding and adjusting the Tillotson HR 36A Carburetor.
Maintenance, repairs, and performance modifications for the Berkeley 6JA Jet Pump.
The factory wiring diagram and legend for the 1969 Model 372. I've added arrows to show the direction that
current is flowing within the wire, and the wire color codes.
The crankshaft seals are very important on a 2 stroke engine. If they leak the engine will run too lean
and will be damaged. Also, leaking seals result in an engine that becomes increasingly hard to start, especially when
hot, and eventually won't start at all. Leaking seals also cause an inability to idle properly, if at all.
Here's an inexpensive adapter so you can hook up a garden hose to your 372's engine and run it in the driveway
for testing/tuning purposes.
If you need a nice cover, this is one of the best available.
