Hose is slightly stiffer than OEM hose. 1/2" Id hose is for cooling system, 5/8" Id is for all oil hoses. 1/4" hose is the size of the bypass tube that feeds to the right front of the ski from the exhaust manifold. All hose is sold by the foot. Ex: for 10 feet put 10 in for the quantity upon checkout.)

Hull Fittings

(Ever had a plastic hull fitting break and dump water in the hull? More than likely it was not due to the fact that the fitting is plastic, the original design has issues. Kawasaki used a steel nut and washer which over time swell up and crack the fitting. The engineer who designed this should be fired! Our setup includes a 304 SS nut and washer, so you do not have to worry about them breaking any longer! Color may be different than what you have, choose cooling or bilge from below.)

Bilge (5/8")       $18.52 ea.

Hose Barbs

‚Äč(Hose barbs fit all models. Brass is a direct replacement of stock fittings, but hold on to more of the hose. If you have ever had a hose pop off, these will prevent that. Made for racing and saltwater. We recommend thread sealant here.)
