Thanks. Do you think a stock 701 would turn the 9/17? The lakes are frozen here so I can't try yet.

I have a stock 2016 Superjet. I just picked up a used 140mm 12 vane Magnum pump with a 9/17 and a 16/23 impeller. How much horsepower do I need to turn each of these?

This new SX-R looks very close in size to the Seadoo HX (390 lbs dry). To be fair the SXR is listed with a wet weight, but dang, it's still a solid 120+ pounds heavier than the old SX-R :o

My guess is that moving the pump back adds straigjt line stability, and would help back flips (if trim were added). I'm not very interested in shortening my hull.

What are the effects of setting back the complete pump, say 2"? I mean actually cutting out the intake and shoe and moving the whole oem setup back 1-2". Has it been done before?

Thanks guys, it's hard to search this board when I'm only browsing on my phone. I assume my jets are stock since they have probably never been off. Any guesses on my top speed with an old school Skat 10/18 impeller?

I haven't run this setup yet so I'm seeking opinions on the jetting. I have a completely stock/original 64X "760" engine (out of a 'raider) and a Factory Pipe "B" mod pipe (the kidney chamber). FPP doesn't offer instructions on this setup... Am I crazy to try stock jetting? Stock hp is 90...

The oem exhaust is already on it, plus it is tuned, bulletproof, and best of all FREE. I do have a b pipe on order but it wont be in for at least 1 month.

I have the 760 engine and exhaust. The exhaust is huge and I know it would require a rear water box. The question is, will the exhaust fit? Also, will the oem flame arrestor (dual 44) fit?

Anyone know if a stock 760 pipe will fit into a blaster 1? I'm planning a 760 swap / conversion (removing a complete 760 from a 'Raider and putting it into a B1). I did a search and didn't see anything about the OEM 760 pipe fittment.

Anyone ever try one of those Mako brand 650 sx / x2 impellers that are on flebay? I'm interested in replacing the oem impeller on my stock X2. The price of a new Mako looks good, but the last time i purchased an off-brand impeller a blade ripped within 10 hours (eye roll).

The price doesn't matter - do you want that ski?

I would guess it's open at the resting position.

There's no piston mark though.... if the markings represent something about the bore sizes, then it seems fitting that the pistons would also have to be marked in a special way, or they'd get mixed up. Yamaha marked the 66E and 66V pistons, I believe (GP800 and GP1200R engines). Those...

Didn't Yamaha make them all? My guess is Wetjet said, "Hey Yamaha, we only want your '00' cylinders".
