Robert;
That looks like a standard car water pump, they use the housing, but the
internals are different. *Different materials, different bearings.

Some people use a replacement from an auto parts store. *It will work,
but for a short time.

Costs a lot to break down, use proper parts.

Agreed on the water pump. The sutomotive type is cheaper, but it has
different , more economical type bearings. why? because on an
automotive enclosed system, the anti-freeze coolant itself is a
lubricant/ rust inhibiter, for the bearings sake. so they don't have
to be "special". PLUS the automotive style will usually have a cast
iron impeller, where the marine is stainles steel.

automotive will bolt on and work, but you'll get much longer service
life out of the O.E marine unit. even though it costs more up front,
it's cheaper, and more reliable in the long haul.
