Evinrude 50 / Fuel problems

[Big Brother]

I have one Evinrude 50 HK 1990 VDO. <br /><br />On my last trip out, my motor was running along fine and then it cut out and died. I soon discovered that if I pump the bulb it run fine even at full speed. When I stop pumping it stalls. I have open the fuel pump, but can't find anything wrong.<br /><br />HEEELP !!!!<br /><br />Big Brother from Norway

Hei!<br /><br />Sounds as if your motor can no longer suck sufficient fuel from the tank.<br /><br />This will happen if your fuel pump is too weak (although al parts seem intact), if the fuel line/filter/bulb is clogged or if the air-vent in the tank cap is blocked.<br /><br />The air-vent is easily checked by removing the cap. The hose etc. may be checked by blowing air through it. My guess is you end up with a defective fuel pump and have to buy a kit for it. This happens and the kit for it contains all you need.

BB,<br />It has all the indications of the fuel pump gone bad. If your ball goes soft while under a load , she's not pumping any fuel.I just replaced my pump on my 70hp evinrude and that was the same problem I was having.Now it is running great. <br /><br />Deuce
