What make is the raw water pump?
I was told that a measurement is required of the current water pump cover.
Most 3208's use a jabsco pump. Measure the cover plate and note the placement of the screw holes and call them back.
If it is a Cat pump you may be correct.
I have a Jabsco no my 3208 and a Speed seal.
If you can't repair it maybe it shouldn't be on the boat
