emmmm Merc dealer cost there is not any profit at 375 period. You must mean the cheap China Brand knock off Sierra brand -------- like this in the link ( Its a Sierra Knock off ) .

https://www.ebay.com/itm/Mercruiser-...-/263025040866 .

This is not OEM Merc and believe it or not the dimensions are not the same -- Sierra does not even know it and wonder if anyone else does either.

If in fact one finds 100 % OEM MERC at $ 375, I would dive full in at that price no matter what because that is less than dealer cost.

Teague what he is showing as well -- He can not even sell it for 375 because he would be losing money on his buy in cost.

Also the online game has no warranty and lets say your great price of 375 item breaks in a month or 2 - from a defect or it was a reman version inwhich the seller never disclosed or was sitting on the shelf for 7 years -- ( great for the impeller) guess what did the buyer save any money - cause that online great pricer is not going to warranty any part of it period. If Teague or myself buys that part thru the OEM and it fails within the warranty period you can bet the OEM will warranty it completely. Link bellow for what some online forums are selling them for.

Can you provide me with the 100 % OEM part currently brand new and with the 100 % full warranty discloser all intact for the 375 price tags or even less. Seriously I am buying 25 of them after you post the link.. Thank you for doing this if possible. No joke cause I can not even buy them for that.

Genuine Mercury & Mercruiser parts. 46-72774A32 PUMP ASSY-WATER Genuine OEM Mercury Marine-Mercruiser part

Look into a dual stage from CP or Teague. And of course the proper set up. Transom water pickup could be on the list for the set up as well. Have no idea your drive and water intake set up

I have transom pickups with arneson's I was just a little uneasy about bleeding water off the cooling system for the intercoolers and effecting the engines cooling to much

I ran stock merc pump with a procharged 750hp setup for years and was fine, barley ever got to 150
