    GPR seat holes

    I know I've seen a few people with holes cut in there seats for better air flow on the gpr's. Does this kill your structural integrity of the seat? Any suggestions for letting more air in without cutting holes in my ski? I don't think it makes much diff but mines a 01.

    alot of people drill holes into the storage compartment for better air flow. I removed the bin in the storage compartment and saw no gains with it off on our friends radar gun

    If you drill holes in the storage bin you have to drill holes in the lid as well
    just removing the bin with out any way for air to get in there will not do anything. You need to remove the visor and dill holes in lid, then reinstall the viser. this will alow air into the bin area and if the bin has holes or the bin is not there more air will get to the moter.

    I found on my 1300 I was able to gain rpm by adding more air. But after a certain point there was no additional gain if you added an additional hole - in my case to test this I actually added a blower and I saw no additional gain when I added the blower

    here is what I did to my ski

    nope just flick the catch over then place screan down resting ontop of catch,very good air flow that way ...

    but i cut both lid and bucket on my ported boat...

    as phill says after a certain ammount it makes no diffrence,try with seat off to see for yourself

    I think it depends allot on when you ride and the temps etc.. If you are riding @ 70 degrees all of the time you prob dont need anything. I did a bunch of testing with the seat completely off and found absolutely no diff in rpm's (I am in Chicago and there are very few 80+ days I am on the ski).

    I think the guys in Tx and Fl etc.. .Need more air / holes.

    I drilled some holes in my seat and stuck some builders small 2.5" roof vents in there. It worked fine with no loss of strength
