    Mech. Trim Tabs and Nozzle Trim Too!

    There were doubters, but I did it. I hope the pictures come out.

    Pic 1 is of the handle - I had to remove the plastic spacer and remove the locating pin on the start switch, but it works. The only interference is at neutral nozzle trim, and it is negligible. I set it there because if you pull the nozzle trigger it automatically goes to neutral anyway due to the exit nozzle pressure.

    Pic 2 is of the thru-hull fitting - It took a leap of faith to drill a hole in the transom, but I did it. That is the only flat surface available back there. You are supposed to remove the nozzle trim and use that spot for the trim tabs, but I wanted to have them both.

    Pic 3 is of the trick turn buckle - When I relocated the thru-hull fitting, the cable was too short, so I found a nice stainless steel turnbuckle to make up the length.

    I know the set-up doesn't look very pretty, but it works well. When going on a top-speed run and the porpoise shows up, a quick squeeze settles the ski out nicely and then a slow release puts me right back up to top speed. Great for the holeshot, too - I can leave full throttle with full trim up as long as the lever is pulled with no unhooking and quicker planing.

    Anyway, I just wanted to share...

    Thank you. I didn't think anybody cared... (sniff).

    They proved their worth today. I was out testing intake grates, and an RXP came up to me when I was on my way back to the ramp. In 2 foot chop, we were both bouncing around and it was fairly even. Then I pulled the lever, the ski stayed hooked up, and the RXP was left behind. They really do make a huge difference in the chop.

    Nice job Eric... I bet that does shove the nose of the ski down as soon as you pull the trigger on it.. I guess you found your electrical gremlin?

    I just put a resistor in to fool the ECU. I now have resistors in place of 3 sensors. Technology is wonderful...

    I still have a low output from the pick-up coil, but the ski runs fine, so that will be a winter project.

    Gotta love outrunning an RXP with my smokin' 64 MPH top speed! Mechanical trim tabs, 3 degree nozzle, single bar intake grate and Skat prop are great in the chop but don't make for a great top end.

    Oh hell, I care!!! That is simply awesome. Anyone who has used mech tabs in rough water (not that 6" chop, but the real stuff) knows what a Godsend the mech tabs are.

    Great job.
