What prop should try next

[Seadoo1xp]

I have a 2005 rxp
et 137+4
50psi injectors
external ic
riva straight pipe exhaust straight out
riva block off opas
rrfpr
supertech valve train
Vtech tune to 8375
solas 15/20r


I hit 75mph at 8325. Is that as close as I'm going to get or can I get another pitch to maybe get closer or get there faster then I am ? An does 75 sound right or should I be faster

stock timing is a joke over 7psi
I bet its holding you back

Really ? I'm only 2 years into messing with these 4 strokes but I feel my setup should be over 75

75 is about all you will get at that rpm with your setup. Springs & retainers and then a higher rev limit & injectors will allow you to get to 80 mph range. You need to run 8600+ rpm to get to 80+ with your setup.

I have super tech valve springs an retainers. Do u think I should get a higher rpm tune and 60psi injectors ?
