Just got an FX SHO
My old 01 seadoo gtx di too a dump so we got an sho.
first question about this thing is does it pick up power running 93 octane?
i havent ever really messed with jet ski's but i have been building turbo/supercharged imports for about 8 years. ( my shops race car... 94 acura integra runs mid 9 sec quarter mile at around 160mph )
i know alot of the newer cars out there will run fine on 87 but on they will pick up power if ran with 93 octane.
and the other question.. whats the first mod you guys would do. I'm reading the forums and seeing that all the bolt-ons dont really gain a whole lot.. I'm more interested in acceleration than top speed. My contacts start to peel out of my eyes at around 60mph anyway haha

save your money and run 87, you don't need higher octane untill you incress boost. I tried it just for jiggles and did not notice any differance. And if you want arm ripping aceleration get the R&D CFM kit. It made a huge differance in mid range on my ski.

there are alot of cars that are tuned for higher octain fuel but can run lower octain with a drop in performance due to knock sensors retarding the timing
the sho is tuned for low octain so there will be no gain with high octain

most hondas are "tuned" for 87 octane but putting 93 in will result in a few more hp once the ecu figures it out.
it seems odd to me, any time forced induction is involved more octane is always better.
higher octane does not mean less energy, octane only refers to the fuels resistance to knock.
both the seadoo ski's we had before were so slow i never botherd trying to mod them.
and if anyone wants a 01 seadoo gtx di with possibly a bent rod let me know.. im tired of looking at it in my yard.

Welcome to the family.
Like everyone else stated, no gain with higher octane with the relatively small boost (5.5 psi) this bike sees. Once you get up above 7-8 psi there may be a need for it.
I hope to have mine up to 10-11 before the beginning of next season. I'm in the midwest so yes we have seasons. lol
