    Newbie?? Why Modify?

    I have a stock 07 FXHO with 90 hrs. Just bought. Mainly will be used on 100 acre lake pulling kids and skiers. I hear a lot of talk on "must do modifies" Things like changing ride plates because you can get thrown off a 55 mph. Were did the engineers over at Yamaha go wrong with the stock parts? my dealer never mentioned one time things I should change out for safety reasons or for performance reasons. The ski itself is plenty powerful for this rookie and seems to run and handle flawlessly.Thanks Gregg

    There's nothing to worry about with that model. Only the GPR & FZR/S are known to overstuff with the stock intake grate.

    It's basically when more water is being forced into the jet pump than it can process. It creates overly high pressure in front of the impeller & causes the back of the ski to jump out of the water, which makes the bow dig in & causes the ski to suddenly hook. The stock grate is designed mainly to keep debris out of the pump, while aftermarket "top loader" grates have a wing that forces water to the top of the tunnel so there's more even tunnel pressure in front of the impeller. The wing also makes the ski handle better & hookup better in rough water because it helps suck the ski to the water.
