Yamaha Wave Blaster 1 Bolt-On Upgrades

Oil Block Off Plate:

A must and really easy to install and remove all the old oil injection parts, Got it from Blowsion, as well as a lot of other parts.

A must if you don't trust oil injection (as I don't)

Bilge Valve:

Also very important, but be wary of these if you leave the jetski moored or sitting on the beach for an extended period of time. Also from Blowsion.
