Sounds like a really good price, I paid 12.5k for my 2015 SVHO with a 2 ski trailer. If you want one of the fastest ski's on the water then go for it and enjoy it. Buy a blow off valve first thing and hit the water.
Thats a good deal. If i was in the market i would buy it.
BTW there is no periodic maintenance on a Yamaha SC like BRPs . If you dont go over crazy over modding it, it will last. The clutch takes a beating when on and off the gas quickly, thats where a blow off valve saves the clutch

I don't think anyone buys a jetski for the gas mileage IMO..

Dumb question, but what is a blow off valve and why should I buy one. I've own jet ski's before and never heard of buying one of these for one. (I've owned an FZR and VX Deluxe in the past)

Just trying to learn here but it sounds like a blow off valve is a safety relief valve in the event that the supercharger or turbo charger overboosts the motor.

It's more then just a safety valve. Every time you come off throttle and close the butterfly valve in the throttle body, the rotation of the engine continues to spin the supercharger causing high pressure to build in the charge tube and intercooler. This pressure will cause stress to the super charger clutch (not a cheap repair BTW, YES took care of that one), the added pressure can also crack the intercooler from the inside, casing water to be forced into the engine (this is a more rare case and usually happens on more modified engines). The blow off valve is connected to the engine via vacuum line to the intake manifold, when there is vacuum (throttle closed) the valve opens and relives the pressure in the charge tube, when on throttle there is positive boost causing the valve to remain closed.
TLDR, its cheap insurance to protect against a supercharger clutch failure and possibly more, you can beat on the ski more (heavy WOT to closed runs and not have a problem). Something only supercharged ski's/boats have to worry about, FZR and VX do not need them as they are n/a engines. Don't by the cheap kits off of amazon or ebay, they squeak and will likely have a short life. HKS makes a decent kit with Riva, one of the best was R&D racing but they went out of business last year, you can still find their stuff around it just won't have a warrantee.
Did my 2010 FZR have one of these
? If so I wouldn't have even thought of buying the safety valve and never even knew it was an option. I guess its discretionary
If I am correct, the FZR was supercharged so it could have one installed. Yamaha dose not include a BOV out of the box, it would have been installed aftermarket. It's completely up to the user but good to have IMO.
