Changed the mechanical trim on my jet nozzle.

[rcguy]

My mechanical trim was set in the down position and I changed it to the up trim position. Since I never go out with more than two people onboard I may get up to plane faster and more top end. Going out today and we'll report my findings. I used a 13 mm deep socket to remove the the top and bottom bolts that hold the nozzle in position. Reversed the bottom insert and reassembled. It took a total of 5 minutes to do the job

My Sea Doo's top end with the nozzle in the down position was 7780 rpm's and a GPS of 45 mph. Will report the difference this afternoon.

Interesting topic. I didn't know you could do this. Not exactly sure what you are talking about but I will wait for results before I add anymore interest, lol.

You flip around that spacer thingie.

I wish I knew more than I did. I would make videos for everything to help anyone else!

Flipped the spacer around, now the bolt is closer to the engine and in the up position. The nozzle (and I'm just guessing) is now about (2) two degrees more in the up position or level position. Now for the results. When I hit the throttle slowly at first the bow does not come up as far as it did in the nozzle down position. Top end stayed the same 7780 rpm but the GPS registered a 2 mph increase or now I'm going 47 mph. Two mph increase with an investment of zero dollars and 5 minutes labor is well worth it. I have heard owners of Sea Doos have spent thousands of dollars for this small amount of speed increase. Go figure?

If you are going to carry 5/6 people on board I would recommend you keep the nozzle in the down position. For me and my GF the nozzle will remain in the up position. I now get better visibility and a bit more speed. A win,win situation for us!

Went out yesterday and opened her up and was able to get to 48 mph according to GPS at 7750 rpm. This Seadoo never went that fast. Gained 3 mph on top end by flipping the spacer around. Beautiful day in November....even for Florida. Air temp 88 and water temp 83.

That was a cheap fix for speed! Water temp 83 and rising... Looking forward to the weekend, myself.

I just got a variable trim nozzle for my Speedster. If I can acquire the rest of the parts inexpensively, I'll have variable trim next spring.

haha try doing that job without pulling the pump out. It took me over an hour to line up the bolt again working between the nozzle and the ride plate. very frustrating haha

I've never had that much trouble installing the pump. I will admit I've found it easier to remove the entire pump as opposed to trying to fish out reverse cable hardware I dropped in there.
