re: dollars Bought all from Jerry at the Green Hulk site, so you can see prices for each there.
He's the best in the country for PWC and Seadoo boats. Listen to his advice.
curious what kind of money you had to spend to get 10mph increase?
how fast does your boat go?
have not been able to get it WO due to chop on the lake. Going to Table Rock Lake in Branson, MO, so will have some slick water to find out top. Have been over 60 mph at 5k altitude lake and only 7,600 rpm or so, so more is there. However, in chop, 60 mph feels really fast and lots of air. Bigger difference in acceleration, which is where you really need it for the most fun. I have outran stock Seadoo PWC W/260 hp engine on this lake and from a dead stop, several boat lengths, so it's more than you can use on this lake and I used to run it wide open most of the time before the mods.
