I really love these boats, has anybody had any experience with adjusting to trim it just feels like at high-speed if I could get the bow up an inch or two the ride would be incredible. I remember years ago I had a JetSki that had trim on it and the performance was phenomenal . Any input is greatly appreciated

Nope.
Been discussed and consensus is that the money spent would be better used elsewhere.
I will say though, trim tabs to put bow down can help but as far as picking nose up, nope. Trimming the pump up doesn't do much for speed but too much trim just shoots it in the air. Check out videos of old school jets throwing "roosters" and look at how the boat planes out. Boat stays the same but the pump shoots up.

I have pump wedges in at the moment but doubt they do much if anything. Brings me up to 5 degrees at pump vs the 2-3 stock. A little more wash and slightly larger wake perhaps but top end was so marginal it would be debatable as to any difference.

Jet pump wedges, that is interesting did you make them or buy them and where did you install them? It sounds like you don't think they were beneficial at all.

I think it would be awesome to have trimable jet pumps. If any manufacturer does it I believe the others will be forced to follow.

I have trim tabs on my boat. They will only trim the bow down. Doing so provides for a much smoother ride in rough water and when crossing wakes.

I doubt trimable jets could do much for trimming the bow up without increasing draft.

But imagine how much trimming the jets down would improve the wake for surfing. I bet lots of owners would be happy to burn more fuel to remove the jet wash from their wake.

Just steal the parts from a couple skis on ebay and start drilling holes and fabricate what is needed.

I actually don't think it would be too hard but cost, and doing it twice, is hindering. That and how/where do the trim levers/gauges/buttons mount?

Guy on greenhulk makes them.
I still have them in. I think they help with mpg more than anything else. And that is even minimal. I also seem to plane out at a slightly higher speed. With both tachs showing 7100-7200 and boat does 27ish. Can't do an actual 25 and stay on plane unless i bring the throttle on one side up then back down again once it catches itself.

With trim tabs I can plane at 14.

I could take video of my wake but don't think enough difference to notice. If i had a ski i would manufacture.
