Just did my 2017 40hp jet. Got the amazon pump, new filters. Friend of a friend told me mercury are bad for hoses deterioration and it clogs the pump. My boat doesn't set very long so everything was clean. Pump sh!t the bed though. I went ahead and replaced all the fuel lines anyway. Warning, the short fuel lines on the vapor separator are preformed hoses. I had to loop my hose around to avoid kinking it.

Well done, love these type of videos as it gives me a preview of what to expect as I take things apart.

I feel confident you’re on the right track. That pump and screen looked horrible. The rust is probably also a by product of it sitting without running, the heat of it running at regular intervals burns off condensation. Good excuse to get out more once you’ve got it pull together 👍

Good job Mr Wallace.Thank you for sharing.Cooling off a little here in North Ga😃thank goodness.

Good luck Mr Wallace

Looks like you got a little work to do but your getting it. Looking forward to seeing you taking Mrs. Wallace out for her first ride in it

Looks like your coming along nicely with it, damn fuel these days messes up everything for sure!

Good luck hope it's a easy fix!!!

Good luck getting the engine running, just be glad you can do it yourself. It is hard telling how much it would cost to have it done. Phil

Check those fuel lines also. No pain- no gain. Can’t wait to see y’a on the water. I’d get a Bimini top. That little bit a shade helps!

Nothing wrong with some new parts start as fresh as ya can. 👊💀

You'll get her fiqured out Mr Ricky ! That's a little different then them old Johnsons with the diaphragm pumps! But once you get that going, that four stroke is the way to go!

One more step closer! :-)

Ethanol ruins everything and letting gas sit long periods does too. Hope it's running good

These pumps are just like those in your fuel tank in your truck. Be careful with the pumps as some are knock offs and cut corners making them...get one which has some reputation do your research. Also replace those fuel filters AND the fuel lines from the tank...many of these lines will NOT like alcohol in the gas and deteriorate rapidly. Any good gas line will work...not one that is coated with a lining. Once you replace the pump make sure that the low pressure pump is not leaking as the diaphragms go to pot after a few years of use. If those leak it will allow fuel into your engine...and we know that is not good. Pretty cheap to replace them...as they are pretty cheap on line.

Thank u

I see you found the canister. Next video mention how important fuel stabilizer is. Our fuel nowadays can do that over winter. A bottle of stabilizer will prevent it. If you have any concern with the injectors, you can get a fuel injector test kit cheap. Some Injectors have screens also. If the injectors are clogged it will still run, but not have as much flow which can lean out that cylinder and burn a piston. Just a little FYI why you are in it.

The good thing is that you caught it now before trying to go out on the water with it. Best with anything used to go over it all, take your time, and get things right. Everyone is too "go, go, go" these days and then get surprised when something goes wrong because they didn't take their time to work out any kinks.

You better spend the money on mercury.. those Chinese parts drain over 5 amps!! Only suppose to pull like 3.2 amps

I need to locate my 2020 merc 150 4 stroke high pressure fuel pump an clean mine out! Any body know anything about em i need help.
