lowering stock sponsons.. how to?
i saw a post where guys said lower stock spons 23mm i think for better corning.. I haven't measured but it looks like I only have about 17mm from bottom of spons to hull line.. do you lower then below the hull line?!? (my guess is based on about 2/3 inch space and 1 inch is 25mm).
also, Any porpoise advantage to stepping the spons like we did the gpr's?

Then with high quality polyurathane adhesive/sealent fill the old holes and re-seal the sponsons onto the hull.
Yes the back edge hangs down in racing they have to be filed flat to the angled part of the hull.
Yes this cured the porpoising on my ski. Maybe loses a bit of top speed but for cornering it is hands down the best setup for the rxp platform. R88
