Well, I dont have the Mercury bottoms, so instead of buying four pumps to make two I think I'll put the block off plates back on and go electric

Airtex 60932 fuel pumps for the sea water mount are just $55.88 thru Amazon: Link: http://a.co/9FlecL7
Many people believe this is whom makes it for Mercruiser.

You could then also get the pumps mentioned above to swap the lowers.

Just a thought.

Edit in: most parts places sell Airtex stuff also...therefore Amazon isn't the only place...I just used it for reference.
Also, I have not done this....just relaying info I've studied. When I did the bottom swap years ago, the Aitex pump was not available outside of Mercruiser.

found this one, thoughts

carter and Airtex Merc used for their stock OEM builds

Norm got your carb done today, going to make two base pulls with his 4150 monday then bolt yours on!

No arm wrestling needed ??

Bring this back up as I purchased a Airtex 60932 last year from Amazon and its leaking fuel out the back diaphragm. Not good, as it just drains in bilge and not the clear hose luckily I haven't put the hatch back on and noticed it. I'm going to try and find a Carter or Merc (I know Airtex and Carter make them from above.) I'm afraid the ones on Amazon are not as good of quality or something, as lasting only 10 months is insane.

I've had better luck with the Airtex brand pumps than those purchased through Mercury. Airtex claims that their pumps are now ethanol resistant. Airtex is also half the price of Mercury so you can have a spare on board when it does fail, and the uppers all fail, with this mounting configuration.

If you have a merc pump, you can bolt on this fuel pump upgrade. 120gph. -8 inlet/outlet
