    Good hack for a throttle lock on an older 15hp?

    I've got a late '70's 15hp motor on my sailboat and I recent got myself an auto tiller for the boat. This is a pretty cool device that will allow me to step away from tiller read a book, have some food, do whatever while the boat is under sail. What it could ALSO do is self steer when motor is...

    JONHSON 25HP 3 CYL 1995

    Well, many will automatically say that your CDI is defective from a previous overheat condition and needs to be replaced. It's an expensive part so if it's possible to borrow a test unit I'd try that. However, if it overheated, I'd either remove the thermostat altogether or replace it to make...

    Help please

    if you still have spark on the other, just take a tester and compare continuity results for each component right back to the condenser (including the plug itself). If that reveals nothing, then I'd replace the condenser and points to start.

    Motor turns when I let go of tiller handle

    Nothing will come apart. It's just a friction screw. I think I may have an extra one of those that I can send to you if you run out of options. I'm in Toronto.

    Telltale installation on a 1965 6hp - on exhaust housing?

    Hi, Yes, I know, there’s no need for this, lots of water comes out the exhaust which is clearly visible but, well I want a telltale anway. I’ve seen some videos suggesting installing a telltale right on top of the thermostat housing which I’m not a huge fan off - anyone see any concerns with...

    30 HP Johnson ... Major problem during reassembly.. any thoughts?

    That doesn’t make any sense. The parts on the stator plate should fit back on nicely and snuggly. Dumb question, are you sure you’ve got the sensor coil on the right way around? If it’s the same sensor coil and the same stator plate you’ve put something on incorrectly or you are using the wrong...

    Johnson 1996 Triple 25hp - can I get better compression if…

    Working on this 25hp triple (1996). Actually, really no longer working on it because it’s now running fine. Compression is 110/110/115 which I find to be on the low side of acceptable. There are signs the engine did overheat previously: whiteness / paint chipping at seam of head and block. If...

    J25reda not starting

    Just switch them - send #1 to #2 and vice versa just in case the original install was backwards.

    1977 johnson 25 hp need help!!!

    The Oracle (Racerone) knows, Michael. But based on what you are describing, me thinks you need to first pull carb, take apart and soak parts for 24-48hrs in your favourite toxic substance (ex paint thinner) paying special attention to condition of bowl, float, needle and needle passages. Finish...

    Johnson 6hp 1962 - Replaced prop shaft seal and now it’s popping out

    Trying to do a good deed for my nephew: his gearcase had a bit of water in it. Got all the parts cleaned and replacement parts put in. When I put the prop shaft seal back into the gearcase head/bearing it went it more easily than I expected. I checked the dia against the old seal and they were...

    1998 25hp Triple - not running past 2000rpm

    Thank you. I will take my troubleshooting efforts elsewhere.

    1998 25hp Triple - not running past 2000rpm

    Also: Compression is “ok” at 110/115/115 and spark is jumping a nice big fat gap. Carbs were removed, taken apart and soaked for 48hrs before being sprayed then thoroughly dried with compressed air.

    1998 25hp Triple - not running past 2000rpm

    I’m working on a 25hp 3cyl 1998. I got this thing only so that I could swap the lower unit with my 35 because I need the 35 to now be a long shaft. Well, nothing is that simple. The 25 I want to sell won’t fully rev. Having experienced this before with my 35, it seems to have put itself in SLOW...
