Water cooling on boat question
When bench running, you have to force feed the water. What I used to so, is rig a gallon jug as a feed tank and hang it about 5 to 6 inches (measured from bottom of the jug) above the top of the engine, and then left the water discharge line from the engine set up normally.
The water pick-up depends on the boat's speed through the water to force the water through the tubes and head. The pick-up line being bent or beveled to face forward, and the discharge being bent or beveled to face aft form a high/low pressure force feed system. (All kinds of math we could get into... It just works.)
Just determine which is the pickup line, and hook it to a water source that will gravity feed while bench running. when yo get the boat to the pond... put the tubes back as they are supposed to be by the boat's instructions and they'll work fine.
