JonBlarc,
probably cheaper than what I have in mind, but the kit I was looking at puts a hose
connection out the back of the boat - you don't have to run a garden hose
into the engine compartment at all ... might be a LOT cheaper tho.
One potential disadvantage - if you forget to put the valve back, your boat will not
draw lake water, and could get REALLY HOT! the kit I am looking at only opens
the "garden hose" with water pressure -otherwise, it's open from the lake, I think even
designed that if the spring fails - it still draws lake water.
Just a thought.
