Hmm, when my engine came out, ONE guy just lifted it up and out...so might be worth it to do - you could have someone help you...many guys work for beer, I discovered! ;-)
My engine was rebuilt, and I asked them to do everything else at the same time, but the young, angry kid who I now know worked on it (since fired) likely did not even check the tranny seals...(see my July 15 post under "Sad News for Rhiannon")
Leaky cockpit covers: get flat rubber washers for the bolts, and then buy cheap stick on foam sealing that comes in strips for doors, etc....but fridge gasket is the best...but I just used the black foam stuff until I could find time to go get fridge gasket stuff....
Good luck...it's kinda important to have gears...however, when engine does not run, I feel we should toss them into the water and laugh as they sink?! ;-)
