We acquired an 800 grate for ours. Over Memorial weekend I went out and the lake was busy AF. Granted, it’s a tight chop, but I was wide open in 1-2 footers and the pump never unloaded. Needless to...

An 800 grate will get you past 71mph , your choice but an 800 grate is still very good in the ocean .

Check out the speed database in the sticky section.... lots of tried and true tuning.

Also, have you milled the head,? .020 can bump your compression up and wake up the ski.

VFIII reeds will give you another 100 rpms on top and better acceleration

It will lower compression so any gains will be lost. Plus there's a lot more to it than just swapping out gaskets. (Timing,fuel air ratio and such) there are other bolt on gains. (Prop,ride...

Good things come from New Zealand. and not just beef and lamb :-)

I have ran over...

Can you please provide more detailed information on the Rideplate mods which you have done.

can you explain a little more in detail. the FF/island racing 4 rideplate mod. I'm lost.

Clean up all the surfaces that need to release the water (trailing edge of ride plate). Make them nice and sharp 90° angle to the water. This goes for pump nozzle, turning nozzle, trim tabs and...
