Wave venture 1100 main seals
Can anyone tell me how to change the main seals on a 1100 63m motor. I've started a new job and going to have my dad put back together the 2nd waveventure I just picked up. The manual isn't too clear. Hoping someone could give me an idea. Does the case need split?

The motor HAS to be out the hull and on the bench.!!
1/. Rear coupler removed.
2/. Front cover removed (with electrical box), flywheel removed, (starter bendix also)
3/. Exhaust removed at ring joint (manifold can stay on.)
4/. Carburetors removed (inlet manifold stays on)---> (it's possible the carbs can stay attached.? flame arrestor only removed.??)
5/. Secure engine upside down.
6/. Remove bed plates.
7/. Remove all bolts holding the bottom cases halves together.
8/. Split case halves.
9/. Slightly lift the crank upwards and remove the seals. (lower the crank back into position for now)
10/. Now, Thoroughly clean both mating surfaces of the case halves (including the seal groves)
11/. Get your new seals and fill the center channels with a good waterproof grease (put aside for now)
12/. Give your case halves mating surfaces a final wipe down with acetone or similar.
13/. Next get your case sealer out (threebond 1211 comes HIGHLY recommended) and lightly coat both mating surfaces.
14/. ? some folks like to put a thin smear of the sealant in the seal groves.? (your choice here)
15/. Now slide your new seals onto the crank ends.
16/. An assistant comes in handy now, get them to slightly raise the crank enough for you to slide the seals into position.
17/. Once the seals are in position the crank gets gently lowered back into the case (it is critical the crank bearing pins are aligned perfectly)
18/. When everything is aligned, the bottom cases half is then refitted and torqued to spec.
19/. Reassembly is then the reverse of the removal proceedure.
20/. Allow a minimum of 24 hours for the case sealer to cure..!!
Do NOT go the cheap route on the seals or sealer.!!!
- Seals will run about $40 or so for OEM, threebond is around $15
Further to the above...
Here is OsideBill's fantastic post on how a set of cases "should" be sealed up..
