I have a closed cooling system on my v-drive (raw water pumped into heat exchanger only). When I start the boat, no raw water is being pumped. If I idle too long, my engine will start to overheat. After the initial start-up, I have to go fast ~20 mph for the impeller to start pumping water. Once the impeller is primed, I don't have any trouble for the rest of the day. I can turn the boat off for awhile and start it back up and it will idle with no problems? Anyone know what could be causing this problem. Also, is this something I should be concerned that it could be causing damage elsewhere in the engine? I start the boat up and run it fast withing the first 5 minutes of it starting.
Thanks!
Thanks!
