I'm going to install a closed cooling system on a Mercruiser 4.3 Vortec with an alpha 1 drive. The motor does not currently have a seawater pump, except for the one in the outdrive. Do I need a separate belt-driven seawater pump in addition to the impeller that is installed in the Alpha 1 drive? -It seems redundant to have two pumps working on the same water supply line.
Thanks,
Mike
