    90HP Mercury 4Stroke EFI Stalling at Idle and Surging

    DB, how is this done? I have VesselView on a 2013 90 EFI 4Stroke, but was disappointed to not find a parameter for fuel pressure. No sensor I assume.

    RPMs fluctuating wildly

    I rechecked the FSM and I don't see any issues. Now I'm thinking it could be spark related instead of fuel. Perhaps plugs or ignition coil. Would you see the symptoms above if 1 of the 4 cylinder was misfiring? Would I expect to see an engine fault?

    RPMs fluctuating wildly

    2013 90hp Merc EFI 4 stroke. Problem began after I changed hi and lo fuel filters, replaced float switch in the FSM, and vac tested the fuel pressure regulator at 5psi for a crack in the hose. Now between 3k - 4k RPM, rpms will jump around, sometimes every few seconds. At 4k and above, it's...

    Thanks for the reply. What's a strong cleaner? Something like "fantastic" ?

    2013 90 4 stroke EFI - ECM errors & Gas in the Oil

    Follow-up for someone that has similar issues in the future: Removing & opening the FSM is easy if you take your time. Label or make a note of all the hoses. Before pics are good to have. You don't need to remove the water hoses (starboard side) unless the case needs to be replaced. I...

    Badly weathered engine cover

    I've got a 2014 Merc Outboard. I don't think the cowl was ever cleaned. What would you use to clean/buff/wax the plastic to restore some shine to it?

    Thanks for the comment. I have the service manual, and it's a help along with 1st hand accounts. The video you pointed out is a big help. For others that have FSM issues: https://www.youtube.com/watch?v=hTRo5ffebYo https://www.youtube.com/watch?v=D6kFiTxL8RI Merc Service Bulletin...

    2013 Merc 90 EFI leaking motor oil when tilted way up

    Some more info on this - The engine oil is coming from where the input shaft enters the engine. If the lower was in place, the oil would be flowing down the shaft, unless the shaft is supposed to stop the flow. Could some seal or O ring be the problem? The oil pours out faster than a loose O...

    2013 Merc 90 EFI leaking motor oil when tilted way up

    The 4 stroke engine oil is under the cowling, but I've never seen it leak. Thanks for the idea tho.

    2013 Merc 90 EFI leaking motor oil when tilted way up

    I tilted the motor way up today to make pulling the lower easier on the back. When I looked at the shaft of the lower, the top 8" was coated with motor oil dripping downward. I went back and checked the outboard, it had dripped about 6oz of oil over the tilt tube and into the motor well. The...

    Tilt Tube maintenance

    I can't get the steering cable off the tube to get a jam nut on. I think I'm left with holding the threaded starboard end of the tube with channel locks or vice grips. What's a good way to protect the threads? If I damage them, I'm in trouble deep.

    Tilt Tube maintenance

    That's exactly what I'd like to do. Unfortunately the port side cap nut with O ring is tight on the threaded tilt tube and when I turn the nut, The whole tilt tube turns. Some how I need to hold the tilt tube while I turn the nut.

    Tilt Tube maintenance

    A 2013 Mercury 90 Four stroke. The grease fitting in the middle doesn't go through to the tilt tube. The grease only gets to the gap between the swivel bracket and the transom bracket.

    Tilt Tube maintenance

    Thanks for the reply airshot. On mine, the O ring in the nut just wipes the grease off.
