Thread: Weekend results
04-30-2007, 09:29 AM #1
So I spent the weekend down at Lake McQueeny with Yellow93 and I took my new ski. Best run all weekend per the GPS was 55.1 mph on the stock 01 XLT 1200. It was a fun weekend, but we had a constant problem that needs to be addressed.
You'd be cruising around between 15-20 mph and then when you'd hit the throttle, it would rev up, but not go anywhere. You'd have to release the throttle all the way, then you could get back on it with no problem. We noticed that when you were doing those speeds, you could see the back was a little too far out of the water, leading us to believe it was getting too much air and not enough water. Ok, so adjust the trim and drop the back down, right? That's when I realized the trim handle would hardly move. You could move it one click down, but not up at all, hopefully this makes sense. So we're not sure if it's in neutral, or where it's at. Any suggestions? Also, could there be another issue we are missing?
Thanks for advice!

55.1 with a messed up trim, 1/2 tank of fuel, and a fat guy driving isn't too shabby for a bone stock XLT if you ask me!
I thought we just had a bad cavitation problem and needed to seal up the pump shoe until I saw the trim wouldn't move... you could see the nozzle angled too far up because of the spray it was giving at speed. I wish I would have had the GPS with me on that last run when going to put it on the trailer because I hit some decent water with the fuel near the buzzer and in superman (That XLT rear hump is no fun on the nuts!) I know I was quite a bit faster than on the 55.1 run.

I would look at the pump & impeller. It sounds like it is cavitating, badly.

anyone else have a suggestion?

Here is what I would do.
1. Find out why you cant adjust the trim up and down all the way. Check all of the cables and mechanisms.
2. With the trim handle in the neutral position, use a dial caliper and measure from the end of the reduction nozzle to the end of the trim/steering nozzle on the top and the bottom. Adjust the cables until the measurements are the same.
3. GO ride it and see how it does. It may be trimmed too far up not creating enough thrust to move the boat.
4. If it still does it check the clearance between the inpeller and the liner.

Pull the ride plate and look at the rear of the shoe, the little black piece of foam in there has probably started to blow out. I had this happen on mine before I sealed the pump shoe. Mine was blown out a little and it did this, then it blew out completely and it was a b*tch to get it on a plane. Seal the shoe and your problem will be solved.
