Was changing out the water pump housing and gaskets lastnight. After removing the lower base, I noticed that the gasket had a gap in it and that the lower base was cracked. I noticed a housing on ebay for sale for a 80-150 Merc outboard. Picked it up for cheap. My question is will my motor, a 69' Merc 800 be able to use this pump base? In the picture, it resembles the one I just pulled off, but I'm not sure what type of motor it came off of with the exception of the 80-150hp description in the ad. Also scored a hopefully working switchbox for my motor for 25 bucks. If it works, I'm happy. Is anyone familiar with an ebayer by the screen name speedo384. He's the one I got the switchbox and pump housing from. As always, thanks for any help!

I hope it's the right one, but I really think you should have bought a new one at your Merc. dealer...<br />You say you bought a housing.. But you actually need a base? (was that just a typo)<br /><br />Does Mercury not offer a new water pump kit for your motor?

It is the housing and the base(the ebay deal). Mercury offers it and I bought it, the upper housing and all the gaskets from Mercury. I never intended on buying the base until lastnight whaen I saw it was cracked. Can you just buy the base? If so, does anyone know where I can?

Did a little research and came up with 46-48747a1 as the pump base for your motor.Still a good number,about $32.As an aside,most Merc/Mercruiser bases LOOK alike,but sizes vary.DHP
