Sudden loss of power - new 30HP Merc 4st.

Hey all,<br /><br />We bought a new legend fishing boat last year, came with a 30HP ELPT 4 stroke outboard motor.<br /><br />A few hours after getting it in the water, the motor would stall under load. It ran fine at idle and at regular speeds - but when pulling a tube at top end it would cut in and out (off/on, off/on) or stop and start. Back off on the power and it was fine.<br /><br />The marina said it was a fuel pump part - made sense to me. So they replaced it. It didn't fix anything. So they put in a whole new fuel pump. That seemed to fix it for the duration of last year. <br /><br />This year it's doing exactly the same thing once again. So either Merc has ongoing fuel pump problems, I got sold a lemon motor or it's not the fuel pump. My limited knowledge though, fuel problems seem to make sense. <br /><br />Any thoughts on what the problem likely is? (I'm also not so sure I want to keep this motor if it's having problems. Any comments on what a marina would say if I suggested I'll pay the upgrade difference to a new 40HP and they take the 30HP back?).

Well, the 40 would definitely be a better choice, however I think the marina would nix the idea of taking the 30 back. They will want more than just the price difference I would guess. If you became a pain in the @$$ to them though, they may be more inclined to make a deal to keep you from coming back and complaining! <br /><br />Stay on them and make them get it fixed, a new motor should not be giving you such trouble. I don't know of anything with new mercs having fuel problems, but a 30HP pulling a tube is going to get taxed to the max.
