    Tohatsu electrical problem

    Well, I checked the engine grounds and found no problem, guess I'll just put a battery disconnect on it for now.

    Tohatsu electrical problem

    Hi all! I have a 2019 MFS40 that recently is giving me trouble. It has always performed flawlessly until yesterday. I noticed upon start-up that it didn't beep when I turned the key, but started like it should. A few hours later I went to start and the battery was dead. Boosted it off and all...

    '19 115 Merc water in fuel

    This is a CT, no spin on, only a small inline.

    '19 115 Merc water in fuel

    I think I found it, a quick Google search shows it's probably a loose wire that's gotten wet or shorted. There's no water separator for a sensor.

    '19 115 Merc water in fuel

    Hi all! I work for a small state park. We're trying to upgrade our older pontoon boat and have acquired a 2019 Aloha barge with a 115 Merc. We were told by the previous owner that a mechanic told them it needed a fuel pump to the tune of $2K. We backed it into the water and it fired right up...

    MFS25 fuel in oil

    Ok, changed out the low pressure fuel pump two weeks ago and so far, so good. I changed the oil again when I put the new one on and have been checking the oil every few days, still right at the full mark. Thanks guys, I hope this one is fixed.

    MFS25 fuel in oil

    Talked to my local dealer and he thinks it's the low pressure fuel pump too. I'll pick it up in the morning. Thanks all for the responses.

    MFS25 fuel in oil

    That's what I'm thinking, don't think there's anything else that'll put that much gas in the oil, but then again, I'm not sure how long this has been ongoing.

    I am a mechanic, just not familiar with outboards.

    MFS25 fuel in oil

    Hi all. It's been awhile since I've been here, these Tohatsu motors are mostly trouble free. With that said, I noticed my 2020 MFS25 smoking blue at startup a few days ago. Figured I should check the oil and maybe change it. When I pulled the dipstick probably a quart of oil came out, needless...

    '23 Merc 15hp EFI alarm

    I'm still curious as to why the overfill causes this problem, any ideas?

    You sir win the prize. In checking closer the oil on one motor was approximately 1/4" above the full mark on the dipstick. I drained about 6oz. out and so far it has run flawlessly. The other motor hasn't had problems the last two rentals, probably used just enough oil to get to that sweet level.

    They are, but the dealer is backed up, maybe get to it next month.

    I'll run that by my superintendent, doubt the state will go for it.

    With the motor level the oil is on the full mark of the dipstick. Do you think that it's actually overfilled? Not sure how this would cause the symptoms I'm having.
