Sounds like the rotary valve shaft seal or the center seal went out. I had like this problem with a 95 speedster eirly on this season. It did the same thing....a cylinder jug got full of oil while it sat, and jumped the cylinder compression up really high (230 psi i think it was). Anyhow I had to start & run a few times to clear it all out.

after you cleared it did it run fine?

Yeah it ran normal after that...but the problem was still there. I was told to pull the plugs out on the problem engine & turn it over a few times to clear some oil out...then fire it up. Also if you have to charge the battery..do not do it while its connected to the boat & dont try jump starting it...you can fry your mpem. <(just some general info there)

If it happens again soon, you'll need to do a leak down test, it could be the rotary valve seal(not likely) or your crank seals, if the latter you'll need a rebuilt crank...

I have a similar situation on a 96 Speedster. Every day when I start it, a plume of smoke leaves one of the engines (a huge cloud of smoke). I didn't think I was hurting anything, but I think I might pull the plugs from now on & clean out the cylinder. So far, it has ran fine for the rest of the day.

I've changed rings a few times on my sleds, but I'm no motor genius. Any advice on where I should look first? Thanks for any help. I'm new to this site, but I'll probably be a lifer. Bought a house on a smaller lake last year & this speedster is perfect!!!

Mark the oil level in the oil tank the next time you put away the boat and see if the oil level is the same when you go and restart the boat. After the winter storage, my Sportster was puking oil out of the exhaust. I removed the plugs, and place a heavy piece of cardboard over the engine so that when you crank the engine, all that oil won't be thrown up on the boat. You can also use a garbage bag, but make sure it a large garbage bag. Make sure all the ignition wires are grounded or else you can ignite the gasoline/oil mixture that will be coming out of the spark plug holes (have a fire extinguisher ready). I now use a hose pincher clamp to clamp the oil line to the crankcase whenever I don't use the boat.
