    Does the house boat have thru fittings or does the intake hose come from the outdrive?

    350 mag water pump impeller change question

    The thru hulls should go to strainers and then to pump motor. If they do something different let us know before doing anything

    350 mag water pump impeller change question

    Serial number of motor? With thru hulls just close them. When the pump hoses are disconnected water will pour into the bilge but only a gallon or so. Check valves are used to keep the hoses more full at all times instead of letting them drain back each time the motor is shut off. Need to...

    2005 5.0MPI fuel pump not powering on

    Most have just one, but could have 2 but will need motor serial number to verify. Probably has a 555 ECM The FP relay is powered ON by the ECM applying a ground to one side of the relay. The other side is powered on by the Main Power Relay (MPR).

    The diodes are close to the relay and inside the harness in most cases. There small and can be over looked

    1999 mercrusier EFI 5.7 fuel pump not powering on

    Code 14 is for the ECT (engine coolant temp). See page 5G-15 in your manual FP relay on 5G-14 I mentioned the MAP only because it uses the same ground connection. The AC Delco parts are fine to use and the MAP is a 1 Bar sensor so 1 atmosphere

    Mercruiser 3.0

    Saying going into gear and not out of gear. The interrupt switch on shift plate should only work when boat is in the water and only when coming out of gear Does "removing feed from the switch" mean the shift interrupter connection was removed? The pickup and module does not need to match but...

    1996 Volvo penta 4.3 not getting power to fuel pump

    Being a carb then FP is powered thru ALT when running and Yel/Red when cranking. Both of the wires have a diode inline so one circuit does not back feed the other. Might just be the diode. Use a meter to check resistance on the diode scale if it has one. Put leads on each side of diode and...

    AQ131A I'm at a loss

    No power to fuel pump or choke 5.0 gl pefs

    Once the carb is filled it should keep running even without the pump running, so we have 2 possible problems. All of the early GL's used Yel/Red from the key to energize the start assit relay and the FP relay thru a diode. Once running power comes from the Alternator Green wire thru another...

    1999 mercrusier EFI 5.7 fuel pump not powering on

    The serial number comes back as a 7.4 L29 Using the same prefix 0L086 I'm close enough to comment. The alarm is controlled by the ECM so just turning the key ON will not keep it sounding off. The ECM is what will turn the alarm ON if there is an issue I think you have the MEFI-1 Code 14 is...

    1987 4.3l 205 high oil pressure

    ok, but the my pic is the block where either the oil filter is attached or remote is attached. Look in the area and you should not see a plug, you should see something with a ball in the center. That is the relief valve location

    1987 4.3l 205 high oil pressure

    Depends on the motor but in the +.002 area more Also with a HV pump the heat is increased so will need a larger oil cooler. A cruise I'm hitting 240 to 250 and lake water is 85*. Have a 3 inch x 18 inch cooler

    1987 4.3l 205 high oil pressure

    The HV pump is what's causing the pressure increase, and from the sounds of it they blocked off the return. Mine has a HV pump but the bearings clearances were adjusted accordingly. Cold idle 70 psi, warm idle 60 psi, above 2500 cold 85 and warm 70 and running straight 40W Check the remote...

    Mercrusier 350 MAG MPI - RPM issue under a load

    Starting fluid (Ether) has a lower flash point then propane. I don't even light using it to start a motor. I wouldn't use either for what you want to try, but would try propane before Ether Would like to use something like Diacom software and get a recording of what's going on. Unplugging a...

    Saying check balls I'm assuming this is you system. Do you have just exhaust mans and elbows, or is there also risers?
