Alright, easy question I know someone has the answer to. I need to know if there are 2 cooling lines coming in from the pump on a stock GPR. I know one goes to the exhaust manifold but is there also one that goes right to the exhaust pipe?

There is only one water inlet and it runs from the transom to the rear of the exhaust manifold. The large water line connected to the exhaust chamber is an outlet.

There is a water manifold attached to the underside of the stock exhaust manifold. You can easily add dual cooling to this by tapping a fitting into the front of the water manifold.



There are instructions on how to do this in our Big Bore Dual Cooling Kit (part# RY10013-BB).

Thanks for posting that pic RC

No problem.
