anyone run Seadoos?

Aha! That explains the use of the word Bombardier.
As to Sea-doos, they look like they would be a lotta fun.

But the ones I have worked on, only a few , I'm sure glad I was being paid to. The engines are buried down low, and do not like to come out. Whatever you do, I highly recommend to stay away from a fuel-injected turbocharged 4-stroker.
KISS;
stick with a 3-cylinder normally aspirated job.

Before you put your money down, you just gotta do a compression test, and make sure the jet-drive works.
And before you put it in the water, go thru the carbs.
And before you head out, make sure you have a tow-rope and a paddle, a can of beans with an opener, and one of them space blankets.
