    J115PL4SR Fuel issue.

    Ok guys we have the manifold off. Inspection reveals that there is a rubber seal between the output of the HP pump and the housing feeding the hose to the filter. This seal is split but it is not shown on the drawings. Can you help us?

    J115PL4SR Fuel issue.

    This 2004 4Stroke motor appears in good condition. Will fire and run if fuel sprayed into intake. Fuel will shoot out of low pressure pump. Have replaced the low pressure filter. Can hear the high pressure pump but only a small amount of fuel comes out of it to the injectors. Not easy to get at...

    Merc 2003 25hp 2 stroke, sad 😢

    If you do need a rebuild don,t try machining Mercasil. Best to bore and sleeve or replace the block.

    60hp Mercury 2-stroke oil injection pump leakage

    If you intend using the pump to cap off the casing hole be sure to remove the drive shaft. If the shaft is left in driving a pump with no oil the pump will seize and the shaft and will tear the crank shaft drive gear to pieces and the bits rip up the cylinder. I found that my drive shaft would...

    Recently acquired and looking for an oil leak at the bottom of the tank, noticed that the lock nut on the oil pump linkage is loose and backed right out, The threads on the rod are exposed a good 1/2 inch. How much of the thread should be showing to ensure good lubrication. Does anyone know the...

    I will look at the kill circuit but at this time I have the following. I removed the carb and checked it, spotless. I re did the cleaning and reassembled. noted that the tubing which bleeds the lower cylinder to the intake manifold had seen better days so I replaced it. Ran the motor and...

    1977 25HP Evinrude cutting out.

    Having mulled the issue over I am going to remove the carb again and go through the cleaning one more time. I could have missed something although I have done dozens of carbs in my time. I will let you know the results. Thanks for your encouragement.

    1977 25HP Evinrude cutting out.

    I thought a lean sneeze as well so I tried opening the Idle jet screw a bit at time until I had got to about 2.5. Smoked a bit more and I got more reside in the barrel but it still went pflut after a while, just as I thought I had it, and it cut out again. I have the ignition advancing before...

    1977 25HP Evinrude cutting out.

    Starts easily and runs for a short time in idle or at higher revs then "pflut" and stops. Restarts without any changes and does the same thing. Carb has been cleaned and rebuilt. Compressions at or near 120. New plugs. Sparks jump a good size gap using tester. Tried fuel pump by squeezing primer...

    1995 Mercury 25hp 2 stroke issues

    It may be something as simple as fuel delivery. For example try leaning it out. Could be the choke is leaking. The primer could also be leaking. It does sound like excess fuel is clogging up the works as has been referenced with the recirculation lines. I admit I am a bit rusty on this model but...

    2003 Johnson J90PLSTC Starting issues

    These motors and all of the similar design seem to be very sensitive to battery condition and cleanliness of connections. Might try there.
