All good buddy, crystal clear many thanks cheers from Belgium

[@KeysBoatingChannel]

Hi Renz, thank you for watching our video! Peace!

[@2BearsOutdoors]

Pretty simple??? Loll . This is a good video.. I bet a lot of inboard owners could benefit from it . Very detailed video.. awesome

[@KeysBoatingChannel]

Lol...Thanks Bro! My intention is to show new boat owners that there are many things that can be done by DIY, and the less you have someone else touch your engine the better it is. By my experience they will always mess something up, you saw the bent on the old fuel pump...this shows you that no one cares to be careful inside the engine compartment. Thanks again for your support! Blessings!

[@2BearsOutdoors]

@@KeysBoatingChannel yes and I totally agree.. This one is an eye opener and a great benefit to those who watches this video .. big hugs and blessings brother.

Hi ! Very well done video ! I have the same engine, I am looking for a fuel pump replacement and wondering what is the part number you got, seems to be hard to find, thanks for your help

[@KeysBoatingChannel]

Thank you for watching our video! Its is hard to find, but this is the one I bought on Amazon Vikter Low Pressure Electric Fuel Pump Compatible with Mercury Mercruiser Marine Boat 4.3L 5.0L 5.7L V6 V8 Replace# 861155A3 935432, or you can go to www.mercurymarine.com/en/us/parts-and-accessories/parts-catalog, and click on Launch Parts Catalog. there you can look up by your engines serial number. Hope this helps.

Hi, here's one of our videos that shows you how to look-up part numbers for Mercruiser engines, hope this helps! Thanks for Watching! kzbin.info/www/bejne/p5bPkIWkZa-Sfsk

[@stephenwachter8171]

Great Video. What is the part number of the pump you are using?

[@KeysBoatingChannel]

Hi Stephen, thanks so much Brother! I will look for the part number and will respond here with it. Thanks for Watching our video. Peace!

[@stephenwachter9689]

@@KeysBoatingChannel Thank you, having a hard time locating the right pump for my 2003 mag mpi and looks exactly like the one you installed

[@stephenwachter9689]

@@KeysBoatingChannel any chance you have that part number?

[@dawsonrossman155]

How reliable are those chinese pumps? just put one in my boat and it died in less then 1 year.

[@KeysBoatingChannel]

Hi Dawson, the pump has been working perfectly so far...but only time will tell. I saw the reviews and some said that it worked fine, and some said it lasted months. Thanks for your comment and support to the channel. Peace!

[@bodyshotjake7475]

Any idea if this is about the same for the 7.4 mpi

[@KeysBoatingChannel]

Hi, thanks for your comment. It should be the same. But check the parts catalog at Mercury.com to see if the fuel pump assembly illustration has the same components as ours. Thanks for Watching! Peace! www.mercurymarine.com/en/us/parts-and-accessories/parts-catalog

[@bodyshotjake7475]

Ahoy! The 2000 2855 with the 7.4 MPI is very different indeed! The pump has the cool flow set up. The 7.4 pump and cooler are buried under the right side of the engine (port side of the boat). It’s a nightmare in the 7.4 MPI 2855 Bayliner. It’s an in-line pump, they could have put it anywhere! The pumps are the same other than the outlet being threaded for some applications and smooth for others.

[@allendabold5611]

your video would be 100% better without the background music very annoying

[@KeysBoatingChannel]

Hi Allen, Thanks for your input. We have done the music adjustments to all our newer videos, the older videos we will in the future update them too. thanks so much for watching! Peace!

[@marchhair01]

I like the vibe of the tunes….

[@markcutshall833]

That obviously was not a new fuel pump, mechanics that pull that crap need to go away !!!

[@KeysBoatingChannel]

Hi, thanks for your comment! Yes, I noticed that the fuel looked the same as my old one, they charged me $430. They will pay for their dishonesty! More and more boat owners are doing most of the work themselves, and they will soon be out of business. Especially in the Florida Keys, its a very small place and the word will get around pretty fast. Thanks again for your support!

[@03SilverMustangGT]

There’s a high pressure and low pressure pump, no?

[@KeysBoatingChannel]

Hi Jonny, yes there is 2 pumps. One on the starboard side of the engine and another in the port side bottom inside a box with the fuel cooler. Thanks for Watching! Peace!

[@03SilverMustangGT]

@@KeysBoatingChannel thx! 😁

[@KeysBoatingChannel]

You're welcome!

[@Nofusscomputers]

@@KeysBoatingChannel Hey mate do u know which one is which? Is the one in the box the high pressure?? Do they boith make a priming sound?

[@jnissy9171]

hi @@Nofusscomputers I have a mercruiser 8.1 HO 496 and I think only the high pressure pump makes the priming sound, yes the one in the box with fuel cooler. PS does anyone know where to find a video of how to replace the HP pump? its hard to get to

[@allendabold5611]

10 to 1 the guy who replaced that fuel pump hit it pretty hard to push it back into that grommet and it bent the neck on the fuel pump. finding a good mechanic in the keys is practically impossible nobody wants to pay them enough to keep a good one living in the Keys seems to be a problem all throughout in most businesses in the Keys

[@KeysBoatingChannel]

Hi Allen! Thanks so much for watching our video! Yes, some people just don't care. In the FL Keys it is a big problem, and after covid, its been even worse. Peace from the Keys!
