What are the signs a fuel pump is going out on a boat?
My 2001 Larson 265 Cabrio has a Volvo Penta 4.3X engine with high pressure electric pump (O.E. # 3857650). I took the boat out of storage two weeks ago, changed the impeller and battery, and off she went. Ran great. The next day I ran her for 45 minutes, took her up to high speed only to have the engine stall DEAD. No sputters. No coughs. Just nothing. However, prior to it stalling the engine seemed to silently miss, like it was turned off for just a split second and restarted full force. Anyways, it did restart. I got home very, very slowly. It died a few more times along the way, each time being more difficult to restart. So I asked the Yahoo community for answers. They said fuel. Nope. We tested it. Pure, not a drop of water. Change the fuel filter. We did that next. No difference. So after that, I took it out this week. It idles GREAT! Starts right up. Lets me rev it to high RPMs without any trouble. So we actually get under way. We made it less than 1/8 of a mile before it dies again, right after I tried to give it some speed. And again, it starts right back up clean but like before we had to crawl back to the dock. What gives? I am now thinking the fuel pump. Does a pump go out all at once? Or does it allow a little gas in but not a lot? It is getting warm… I want to get to my dock on Lake Michigan… and this is driving me nuts. Thanks in advance.
