Loss Of Power When Warm!

[KARL LONEY]

Hi, i have a merc 175 efi and it runs fine when i start it but after a few minuites of motering i loose power and it cuts out as if there is no fuel!
There is fuel and i cleaned the filters out, can anybody help?

Re: Loss Of Power When Warm!

First confirm that it runs out of fuel by priming the bulb when it starts to lose power. Sheesh, I don't even know if efi's have bulb to prime. But make 100% sure that fuel is reaching the engine. Even if you have to add a bulb or something. If the engine gets better when you're force feeding it fuel, you've eliminated a hellova lot of other "maybes".
