    Weekend from hell...Need a fuel pump

    Anyone have a good place to get Mercruiser parts online? I had a fuel pump go bad this weekend. (after we had driven 4 hours one-way) Three Mercruiser dealers did not have the part in stock.

    The worst part was that when it first died, I was anchored with about 5-6 Mastercrafts. My Tige was the one boat to not start. The call over the radios went out "Hang on guys, Joel has a Tige".......how embarrasing.

    To top off the weekend, we got a flat on the trailer 10 miles away from the hotel on the way home. Wrecked the rim. Trying to find a new rim and tire in Minoqcua on a Sunday is next to impossible. Had to drive 180miles+ to find one.

    From poking around on the web, it seems that for my boat (1997 PRE2150wt) which has a Mercruiser EFI 350 Magnum Gen+, you can't buy a fuel pump. You have to buy the cooling kit along with it, which I already have. So why do I have to pay an extra $100+ to get something I already have??

    Does anyone know of a different setup I could use? Anyone know of a place where I can get a pump only??

    I know you are going to ask, but I have not checked the volts at the connection, but you could hear the thing going. Was making noise you could hear above the engine before it died, so I'm pretty sure its the pump.

    It seemed that it only failed after it sat for a while and got hot. If I could get it started, it would run fine once the water got moving through the pump to cool it off. Once it sat there, it would not restart, or it would restart and just burn off the gas in the line and then die.

    Check my post "FUEL PUMP?" as I just had a similar problem last week. Although I'm happy to say mine ended up being a fuse only, while trying to diagnos it I did find the fuel pumps (without the colling kit) on ebay out of Maine. Good luck-hope your fix is as easy as mine was.

      Check this link. I found it while trying to decide whether to fix my alternator myself or have it done.

        I am experiencing similiar symptoms with my 99 22i with the MerCruiser 350 315 MPI. Your anti-siphon valve may be contributing to your situation as well. I found if you take the cover off the fuel pump once this happens and shoot the pump with ice chest water (from the melted ice) with a water gun it solves the problem and you are back in the game.

        If you remove the pump assembly, if the pump has screws underneath going into the water cooler than you can replace just the pump. I am going to replace the assembly as I suspect that something may be blocking the cooling rails on the cooler not allowing it to cool the pump properly. I mean it worked great for 7 years and 440 hours, I figure I will take the hit although I am price shopping the unit. It is $293 up here at Lake Powell.

            Sorry to hear about your problem. I experienced similar problems with my 2150 as well at Lake Powell earlier this month. You might want to read this thread.

            The part fuel pump part # should be 861156A 1 but is No longer available by itself from Merccruiser. Here is TSB I found.

              I think I will replace the whole assembly as well like teachercop.
              Maybe they don't make it any longer for a reason?
              Maybe it's an upgrade?
              Maybe the pump fails because of overheating due to a problem in the cooler assembly? If you replaced just the $185 pump it may have a shortened life?

                Might be true that there is a problem with the cooler I suppose, which originally caused the pump to fail. According to one dealer I talked to this weekend, the reason a lot of them fail is because the pump CAN overheat when the cooling lines get blocked. So maybe replacing the whole thing isn't such a bad idea??

                Stoneman, I did read your post last night. Good thing it was just a fuse (they're CHEAP )

                TeamAllen, thanks for the other thread, I'll read up on it.

                We did pull the anti-siphon valve off (right on the tank) and it was free moving, si I don't know if thats the problem.

                One other thing....could this be a result of water in the gas tank? The fuel overflow valve IS below the waterline. The fuel/water separator had fuel in it, couldn't tell if there was water in it w/o dumping it into the lake....bad idea....

                One guy who was there and does a LOT of work on boats and cars thinks there could be some sludge in the bottom of the tank.

                More thoughts?

                  Since I am right here with you regarding the fuel pump, continuing with my thoughts, gasoline sits in the pump during the off seasona and periods of extended inactivity. Fuel stabilizer aside, the pump may get exposed to the gasoline varnish, a bit of water and such. I figure this exposure has taken its toll. In addition, if you have ever fried an impeller, particulates may have migrated to the cooler rails and partially blocked. Unlike a vehicle that tends to get used frequently, the fuel pump on the boat may have a shorter life and replacing the fuel cooler assembly is the way I will go to hopefully return to the reliability we had.

                  My thoughts on the matter. The boat mechanic up here in Powell believes you could probably go with just the pump. Then the second mechanic suggested the entire unit. Flip a coin....

                    I think I'm going to not mess around here. I am going to get the entire assembly and replace it, plus I'm going to replace the anti-siphon valve. I have another trip with the boat coming up in 2 weeks, certainly don't want to be sidelined then too.

                    Is that 350 considered a big block or a small block?

                    Also, anyone know what size that anti-siphon valve is? 3/8? 1/4? (1997 PRE2150 w/t)

                      Big block. Check the link I added earlier and you will get the part numbers. If you go back to their main site, you can look your engine up by serial number.

                        That link says the 350 is a small block. In 1997, it seems the only big blocks made were the 7.4L and 8.2L.

                        Otherwise, order is placed.....now I just hope thats the cure

                        Thanks to everyone for their help. I'll report back what the end result is.

                            Lot's of good info in this thread. I never thought of it getting too hot and burning out the pump. That is a possibility.

                            ...sorry about the Tige' comment on the radio... At the time I didn't realize that you were actually broken down
