    Once the motor is out, you could get it Bench running. A 20" x 20" plywood, two 20" long 4 x 6's. Lay the 4 x 6 on side and set your tablesaw at 29* and rip it leaveing 1" of that rectangle. Secure the three with 2" course drywall screws. Buy four motor mounts and secure with #14 x 1 1/2" wood screws. I have a crane to slowly set an engine with belly-plate attached and m-mounts on the box and mark where the motor mounts fasten to the 4 x 6's. I keep a spare 720 E-box complete, also with a start/stop switch & buzzer. I use a small jar with two 1/4"id x 20"l fuel lines as a gas tank. I go thru the magnito, rotary, intake flange oil pump (do the shop manual flow test), new 3/32" injection to RV cover spigot tubes so as your drill runs you watch oil flow, rebuild carb(s) attach tuned pipe And Start the Motor. Usually 30 seconds for testing. I also test the over-heat system buzzing.

    Rinseing your gas & oil tanks is fine if dryed completely. Read the Carb Adj STICKY in its entirety, obtain metric socket set as Seadoo = metric, a pop-off tester, 24' x 1/4id ethanol resistant fuel line, can of carb cleaner, impact driver, obtain a Shop Manual. ONLY buy genuine Mikuni Carburetor kits and replace the Needle(s) and Seat(s). http://www.seadooforum.com/showthrea...or-Adjustments

    I cut two spark plugs at the porcelin base and weld a large 5/8" thick eye-bolt to them for lifting the motors out of ski, or in.

    A very large washers would work, as shown in your shop manual tool section.
