Re: mercury 50 hp problem

Try to rebuild the fuel pump. It's an easy job and it's cheap.

Re: mercury 50 hp problem

I dont think this is fuel pump because when i push the choke, engine slows down it means have too much gas, instead off accelerating, when the fuel delivery would be bad
what do you think?

Re: mercury 50 hp problem

Have you adjusted the carbs in the lake in gear as it takes both back pressure and load to set them properly.

Re: mercury 50 hp problem

ok I just cam back from the lake I adjusted carbs and motor was running quit nice then when I approach idle speed and then neutral starts stalling again then I push choke for a sec and goes ok then stalls again I think it is steal something small clogging carbs or maybe fule pumo but this one seams to work ok
I will try to clean carbs again abd than I will see.
Thanks for comments.

Re:2001 mercury 50 hp 2 stroke fuel pump rebuilt

ok I followed your advice and I went to marine store to order rebuilt kit that should be cheap and labor easy. So when I asked, the guy said $ 21 for diagraph kit and $ 50 for gasket kit(total $ 71) Than I am thinking if this is cheap let me check how much is brand new fuel pump. It is 114.17. So now I am confused, should I buy only diagraph or maybe add gaskets ( together $71) or just buy brand new fuel pump 114.17 what kinda make sens it is only 40 bucks difference and I don't have to deal with cleaning and putting stuff back together. How this is working can I just buy diagraph and then reuse gaskets, the engine is 2001 so I am thinking they can be pretty worn out or just buy new fuel pump for $114.17 ?

First of all, don't ever go see this guy again, NEVER.

All you need is in the diaphragm kit (21-857005A1 @ 21$). First pic.

The one at 50$ that he's talking to you is the master gasket set (27-828553A97), used for a complete powerhead overhaul, wich also include the diaphragm kit. Second pic.

Okay long time I did not laugh so much. I bought diaphragm kit only $21 and you right I will go to see this guy only one more time to tell him or his manager how unqualified and stu.. he is.
Thanks.
