You can buy an electric idle stepper from a 1980's GM car for cheap, put an idle up switch on the dash when cruising in the dock area, simply flip the switch for an adjusted idle rpm.

Used it on both jet boats and rock crawlers.

Makes you look like a real pro.

That's a great idea, thanks for the suggestion and the link. I think this would be a much better idea than adjusting it directly at the carb.

People might disagree but I can say I added the large rudder in my 20.5 it to me it was a pretty big difference.

got a link for that by chance?

My dad just bought an early 90's Carrera Elite 20.5', 454, jet w/ jetovator and trim adjustment. We've figured out the proper trim to maintain good control at high speed but at low speed it is very difficult to keep pointed in the same direction. We had a similar boat 15+ years ago and even though it did not have a jetovator it is much easier to control at low speed....at least as far as we can remember.

So, what could we be missing that is causing it to be problematic at low speed? Is this normal function of a jetovator? Are we missing fins under the boat or the jet? Could this be sorted out with the trim (we've tried playing with it but it doesn't seem to make a difference).

I've searched this forum and Google so any help you can give us would be greatly appreciated. Thanks!
