    Low fuel pressure on a 5.0 MPl Mercruiser

    My 2003 Mercruiser Alpha 5.0 serial number Om626769 has me stumped. I replaced the fuel pump with a Quantum E11004 recommended by one poster on this forum. I also replaced the fuel pressure regulator inside the Cool Fuel 2 module plus the one on top of the rail. Two fuel pump regulators? Oh...

    Fuel outlet connection on Cool Fuel 2

    Just replaced my pump and pressure regulator on the 2003 5.0 MPI. When inserting the hose assembly (8M0122042) that runs from the fuel cooler up to the fuel rail I noticed something that seems odd. Where the hose plugs into the copper fuel cooler this apparently is a swivel or a loose fitting...

    5.0 MPI warm start issue

    Update on my two year old intermittent warm start issue with my 2003 5.0 MPI. When restarting a warm engine it acts like it is not getting fuel. Will barely run for a few moments then quit. Re fires immediately but dies. I have experienced this 3 times now since 2022. I now carry a fuel...

    2003 5.0 MPI problems

    Update on my problem. I bought a fuel pressure test gauge and hooked it to the port on the engine. Fuel pressure initializes to a little over 40 lbs and then drops back to 35. Engine running it holds around 33 lbs. This problem has not shown up again since that one day on the first weekend out...

    2003 5.0 MPI problems

    This is an Alpha Drive 2003 model. Engine serial number is OM626769. When looking at online parts diagrams it shows two fuel pressure regulators. One is inside the cover on the port side of the engine close to the pump. The other is located on top of the engine on the intake manifold...

    2003 5.0 MPI problems

    Had intermittent problems on water yesterday. Boat ran good the day before but after taking a short run up the lake and returning to the dock to wait for guests I experienced a problem getting the engine to run. It would start up immediately but run very rough and would not take the gas...

    Bravo 2 with chatter noise when turned full left

    Just replaced the gimbel bearing and both u-Joints on a 2001 Bravo 2 and we noticed a chattering noise when turned full left. When the steering wheel is move slightly back to center the noise goes away and also we do not hear the noise if the drive is moved to full right. It's only in full...

    Alpha One Gen 2 strange noise

    While running the engine on the trailer with the ear muffs and water hose, if I put it in gear and advance the throttle I hear a strange screeching noise if I pull the throttle back quickly. If I pull the throttle back slowly I don't hear it so much. It's only when I rev it up some. My son's...

    single point water draining system

    I have a Mercruiser 5.0 with the single point drain system for draining the engine. Last season I constantly noticed water in the bilge after each outing. Since I trailer this boat I suspected a leak somewhere in the cooling system. It was not bad so I did not address it immediately. Now while...

    New Mercury 4 strokes

    I've been told the Mercury 40,50 & 60 four strokes are made in China. Can anyone confirm this?? I'm in the market for a new engine for a new pontoon and will probably go with a 70 or 90 hp since these are supposed to be made in Fond Du Lac. Looks like this engine uses the same block size...

    EZ Load trailer issue

    I have a tandem axle EZ Load under my 21 Sea Ray Cuddy. It seems everytime I load the boat now it is not level on the trailer when I pull it out of the water. The boat sits level in the water, the rolls and arm assmeblies are all the same distance apart on each side. This is something that...

    Power trim and tilt question

    I have an 1989 50hp Evinrude with power trim/tilt problems. The motor runs but needs assistance to tilt upward. Tilting down is no problem. I have checked the fluid and it seems to be nothing but auto power steering fluid. I added some to bring it up to the fill hole level. I have...
