Ran the boat for the second time this year and started having problems with the boat overheating when idle. When moving the temp dropped back down to normal operating temps. Soon as we stop and idle it starts to warm up again. We pulled the boat out and hooked up a garden hose to the water intake. Ran it out of water fine idle for a good 30 min no problem at all. The temps stayed right where they should.
Does this sound like the water pump going bad? or does anyone else have any ideas?
