ID:	283217Water cooled. Look up "pisser" on this site. That may be clogged. The pisser is a small hole on the side of your boat below the rub rail where hot water comes out after cooling your exhaust. Many times mud wasps or other crap gets stuck in there. You can stick a wire up there like a coat hanger or stripped single strand wire that is stiff enough to make it all the way up the hose. I like to disconnect the hose on the top of the exhaust and blow through it to see if the pisser is obstructed before I even try. All it takes to re-assemble is a zip tie in most cases. If your pisser is not clogged and IF you had a couple inches of water in your hull after your 2 minute run, your main fresh water intake may be disconnected from your muffler box.

    I hope thats the case, however if it is not and it pisses good your looking at going through the carbs, if its bogging, its probobly the carbs not putting enough fuel into the pistons and causing it to heat up more then it should.

    The jetpump creates a pressurized water stream. the cooling water for the motor is tapped into that pressurized water and runs up to the engine. Water enters the bottom of the exhaust manifold 1st, then into the cylinders and out of the cylinder head. From the head it goes out to the exhaust pipe and out the pisser and out with the rest of the exhaust.
