I am a bit new to posting here at the site. I have read all of the posts, and have learned quite a bit. I purchased a 99 Speedster last year in September, twin 110's. Late in the year for Michigan. Everyone was pulling their boats and docks out, and I was just getting started with the Speedster.

My questions for the group is, what type of injector oil do you run in your Speedsters? I also own a 98 Seadoo SPX, with a 110hp motor. I run either Amsoil synthetic or Sea Doo synthetic in it. The Speedster has two of basically the same motor, so my thought is to use Amsoil in it as well. The original owner that sold the boat to me, had topped off the oil prior to me picking it up, and I never did ask what he ran in it.

Any help would be appreciated.

I use the regular Bombardier oil, not the synthetic. I found some Quicksilver today, that is made specifically for PWC's, and has the API-TC specification that Seadoo calls for for my specific Doo.. This is not the Quicksilver for outboards, however. That oil is NMMA ashless (tcw 3).
I have read about the Amsoil before, but haven't seen it anywhere in 'bama...
As long as the supply of Walmart Bombardier oil holds out, I'll use it.

Thanks Tigger..

When I run the regular Bombardier Rotax oil in the '97 SPX, with the 110, it fouls the plugs every time. Have to run the synthetic in it.

You think the regular Bombardier is fine in the Speedster with the 110's?

Dunno....the engines are the same, so it might not like the non-synthetic.
The 720's (85HP) like I have don't specify or need full synthetic. Your 110's may. I haven't fouled a plug yet. Which plugs are in the Speedster? I use the NGK BR8ES....
