Hi All. This is a great source of information. My thanks to all who contribute.
I am in the final stage of building a mini jet boat using an 08 Waverunner XLT 1200 power plant.
I need to decide what to do with the pissers. Are they necessary for cooling or can they just be plugged and the water will flow through the exhaust? I suspect that I should plumb them overboard but would like to know for sure. Thanks.
A couple of pics for the curious.
