Difference Between Rotax 200 and 250

[ScottyOK]

I've seen 44mph on a glass smooth lake with my twin 150's. Never had any regrets while pulling folks in tubes and such even with a several people in the boat. The child in me wishes I could hear a supercharger whine and 56mph!

Guys I am a Seadoo NUT and have been working on them for 25 years. I have owned 3 Jetboats and love them all. The Rotax 1503 is a 1.5L 215hp motor with a internal Intercooler and also comes in a 255-260 External Intercooler model with Upgraded SCer, Injecters, and ECU mapping. They are the exact same Motor. The new 1.6L ACe and 1.5 ACE are a bit different. Also horsepower ratings have been said to be 200-212 and also 240-250. The new 1.6ACe horsepower rating is pretty much on par at 295hp for the 300's I wish they would make a boat with the NEW ACE 1.6L 300 motors..... Zing.
