97 gp760 hopping out of water
my friend has a gp760 no mods at all but it comes out of the water very easily. even in flat conditions when he hits a super small wave it just starts pounding now would a intake grate and ride plate fix this? and adjust the sponsons up more??
what should i do?

by the way if anyone can confirm that those mods will help then if anyone has a plate or grate to sell that would be greatly appreciated.

Trim tabs help...and shimming the back down will also help ya out bro!

the 97 has the factory long plate.. which is good.. shim this down in the rear aprox 3/8 to 1/2 inch with longer bolts and stainless washers... get the trim tabs designed for the 97/early 98 (they are different than the late 98/ ).. these are no longer made commercialy but you may find a set custom made..look in posts by obx jeep refering to a member here..slaw (his friend custom makes them..)search trim tabs in the old school section and you will find some info..
a two bar top loader grate will keep your pump full and help aleaviate cavitation which is a contributing factor in the bounce your experiancing..
o/e sponsons do more for handling than in controling the ski's attitude... you will read various recomendations on a gp hulls... with the 760 twin, you need down force on the nose... on a gp1200tripple the engine adds about 50 lbs to the front, those fellows with high hp motors and tripples run in a more nose high attitude because the weight helps to let the hull ride a touch lower in the water...they benafite from positive shimming ( washers in front on the plate not the rear)...my 2 cents from owning a 760 twin gp..

thanx alot guys
i will be sure to let him know that.

Bah... Lowering the plate scrubs too much speed. Just spend $85 on a set of trim tabs. It will be the best money he has ever spent on that ski...

He will need both the tabs and the o/e plate adjustment's.....you forget, you have the ultimate speed scruber plate installed on your skiand besides he does not want to get his friend faster than he is, lol.. just safer!!!
