Re: Trim Tabs .. 14' jet drive
I've run them on a 14 foot jet boat, sj 95 powered... (sugar sand heat) They made a HUGE difference. I can't really even explain how much they changed the boat! Without them, getting on plane was sluggish, and with 4 people in the boat, there wasn't even a chance of getting on plane.
After adding them, it pops up nearly instantly onto plane, and stays on plane at a much slower speed. The only drawback is that it makes it substantially more stable. It will not spin easily, if at all. I rigged up a wire hook system on mine so if I wanted to go play I could hook them up in a full 'up' position, out of the water. Unlike prop boats that gain a little speed from them, I maybe lost a very slight bit of speed, 1 to 2 mph max, but it was easily worth giving up that.
(btw, i got the ST980-40 model, seemed like a fairly good fit.)
