Seadoo HX speed question????

[speedracer01]

I've got a 1995 seadoo hx that in my opinion is pretty quick. It is bored .40 over, has light exhaust porting, a factory pipe with ecwi, micro touch rev limiter, xp 40mm carbs, primer kit, tau ceti flame arrestors, jetworks flow control valve, etc.... Everything else is stock as far as mods. It ran about 60 +or- yesterday on the water. What mods would anybody recommend next for a little more speed? Rideplate, impeller, bigger carbs, aftermarket head, etc?????? Any help would be awesome! Thanks!

if you hit 60 you have it all plus 5mph for the mods listed.
my 785 mod race hx goes just over 60.

[speedracer01]

I hit 60 with just the mods that I listed.

Best mine would go is 58 GPS'S on flat water with the same mods except aftermarket carbs so I think that is good speed and I would be happy if my HX runs 58 with the stock 787 but waiting on a waterbox to try it out. How much do you weigh? I think someone that's got 50 pounds less might go faster then a guy with 50 pounds more. Either way thats running good and if it ain't broke don't fix it.

I had a 800 with pipe,head,carbs,mag pump & it went 60 & would beat my 720 SS any day.

My guess is the gps is about 4 mph high

exactly dan,but what would we know?

miller stage five 785 superstock engine
48 mm novi carbs
factory spec 2 pipe
set back magnum pump 16/22
60-62 mph at 7800 rpm.

try another gps.

and then try a skat impeller .

I was also sitting right beside a bass boat doing 60. I did it just to the gps, because I didn't believe it either! I weigh about 162 or so.
