Electric Trim and Pump Wedge
So now that my 99 SLH is up and running, I notice that it needs to be trimmed almost all the way down for top speed.
Would it not make more sense for the top speed position to be near the top of the trim range? It seems that any position above this would be a waste. Yet being able to trim down more would help with stability.
I believe based on the markings on the trim gauge that the trim has a maximum range of 10*. I also believe my ski has a 5* wedge.
I was thinking I would like to find a 2 or 3* wedge and flip it upside down, which would put my max speed position near the top of the trim range. Looking to see if anyone else has changed their wedge on an SLH?

What kind of water are you riding on, smooth or rough?
Try a 4* (stock) wedge and see what you get.

Mostly light chop. Depends on the day. As much as I want top speed, the ski is unusable some days when the bay is busy.
I figured if the markings on the MFD are in-fact approximate degree markings, then I know I need to lower the trim at least 3-4* to put max speed in the middle of the trimmable range (if that makes sense). So by that train of thought, I figured a 2* would be great. Put me in the middle of the range installed correctly and near the top if flipped upside down.
BTW: I believe my wedge is stock, whatever it may be. Quick look using a framing triangle was about 5*, could be 4*.

I have driven many Polaris SL's over the years, being around 200lb then, I could never put the trim more than 1 mark above center for top speed, with the exception of my 93 which had no pump wedge, I don't understand why Polaris put a wedge on a machine with trim in the first place, you dont' need both. a smaller wedge would be better for you, cause right now even in the middle position your pump is trimmed up a bit with the wedge. No wedge would be best, but that change affect the position of the trim rod, you will have to be "trimmed up" on the gauge a little, your steering will have to be adjusted slightly because you are moving the nozzle in a bit & be very careful if you try with no wedge to make sure the water supply outlet going to the tube connected to the hull has enough clearance or when you tighten the pump bolts you can crack the nozzle!

A wedge is much more effective in "trimming" the bow than the trim. The trim has to bend the exiting stream of water, where a wedge does not. It is only meant for small corrections.
To the OP, are you sure you have your trim adjusted correctly? When the gauge reads 0, is the nozzle perfectly straight? My 2 seaters wouldn't ever take much trim at top speed, but they were always over 0 in smooth water, even with a 6* wedge...

I agree with Polaris Nut. Make sure the trim nozzle is centered when the gauge reads zero. I can ride my SL's with the trim up quite easily, however the smoothest riding on rougher water is with the trim down. If you want better rough water riding, get an Ocean Pro ride plate.

It sits just below center when the guage is centered. The trim guage is in sync with the trim motor. My buddies 00 SLH is reacts almost identicle to mine. On his, you need to be trimmed 3/4 down to achieve max speed and mine is 7/8-3/4 down. I would love to remove the existing wedge, but would infact, as mentioned, require a shorter water tube.
My Tigershark operates as you would expect, trim up is max speed, trim down is stability in chop. just supprised polaris put a wedge on somthing that had no use for it.

If you want a smaller wedge, there were a few 2* ones in the classifieds a while back. Not sure if they were ever sold.

Ive checked the rear end. All tight, stock grate and rideplate. It just goes slower. What confuses me is that my buddies does the same thing (1 year newer). Im going to try to grab a 2* from Jeff tonight and see what happens. At least its an easy swap and not a ton of money invested.
Considering the MFD read 60 MPH trimmed down on a 700, I would assume that I was infact trimmed correctly with no major problems.
Thanks for the responses!
