[lexi60]

Hi! New here and a fist time boat owner.
On to my problem..
I have a 69 mercury 1000, 100HP
Sn 2573845. The part number on my base is 46-48747.
removing the impeller, to find out both the upper and lower housings are split!
I've been googling new housings... Only to come up with sierra # 18-3317

http://marinesupplydirect.com/Sierra-18-3317-Mercruiser-Water-Pump-Kit--1-Lower-Unit-P702606.aspx
But it says for sn 27xxxxx And up.
I'd love some help.
Thanks!

Re: 69 mercury water pump housing.

I was searching your serial numbers on **********, and it seems you might have a 1000BP? it is August 16th and I'm not sure if you've been helped, but I'm hoping I can. if this is the set-up you have, it's sad to see most parts are Obsolete for this motor. Wow! that's bad. search boats DOT net under 1000BP
