Full StarEmpty StarEmpty StarEmpty StarEmpty StarPart does not fit
by Ed from Essex jct, Vermont on July 27, 2015
There are two different size bases for this water pump.The dealer knew exactly who I bought this from. He said they never ask what size the base was on old pump. The one I got was smaller than then old one and leaked outdrive grease when installed. The two different size bases are close enough that it is hard to tell there is a size difference unless held close together. I ended up taking outdrive to dealer to learn this at a cost of $135.00.

by Jarold from Henderson, Nevada on October 21, 2014
While it did come with all the gaskets you could possibly want, the base however was to big to fit in the MR/Alpha housing. Not sure when the size change occurred but if you order this unit be sure to save the old pump housing base to reuse or you will be screwed!

by Robert from Livingston, California on August 16, 2012
Never again will I substitute another brand impeller to save money.This inferior product never made it to the water.When I started the engine WITH WATER HOOKED UP the impeller housing reached 300 F.After replacing the old VOLVO impeller it ran at 72F.This was an expensive lesson.

Q:
I have an ALFA1 SN# 0B662125 is the Sierra 18-3320 the correct part for me. What does 'MR' stand for?

This would be the best replacement for your Mercruiser engine. MR generally stands for Mercury or Mercruiser.
Q:

Yes the Alpha 1 (pre Gen II) went from 1983-1990. So this kit will work for that outdrive.

A:
18-3320 is called for Mercruiser MR/Alpha outdrive. MR/Alpha ranges from 6854393-D594568.

This is not the right kit. Alpha 1 Gen II motors began in 1991. MR/Alpha outdrives were from 83-90. So 18-3320 is the correct kit for your outdrive: http://www.iboats.com/Water-Pump-Kit-18-3320-Sierra/dm/view_id.187582
