    Flywheel magnets destroyed in Tohatsu M40C

    Flywheel jammed the other day in my Tohatsu M40C, which has been having ignition troubles. Removed it to find the inside magnets destroyed, magnetic flakes everywhere (see pics). Any idea how this could have happened?? Certainly want to avoid this happening again... https://imgur.com/LWBYIFn...

    Tohatsu M40C Popping/Surging Rhythmically

    I recently purchased a non-running Tohatsu M40C. I got the motor running this morning, and it seems to run smoothly, but every second or so the engine pops and surges in RPMs a bit, repeatedly and rhythmically until I shut it off! To get the motor running initially, I diagnosed that it had no...

    Frozen Driveshaft Preload Pin- 1988 Mariner 45hp

    Finally got the lower unit off my Mariner to replace impeller, but the preload pin on the end of the driveshaft seems to be frozen in place. I’ve been soaking it in penetrating oil and whacking it with a hammer.... no luck so far. Am I right to assume this pin should spring back up when...

    I feel like I’ve tried everything with this motor... model #J25RLESB. It was running fine a few weeks ago. Tried to start it up last week and wouldn’t start. Noticed the primer on my hose was breaking down so replaced that. It’s got the manual pump-to-prime system, and I noticed a backup...

Looks like mold or something. Can anyone identify this? Is the starter salvageable? I’ll try and get...

    Mercury 9.8 high revs at idle, fuel spilling out from carburetor

    Hi everyone, I finally got my 1983 Mercury 9.8 running for the first time (I bought it non-operational). Thanks for all your help. A few days ago, the motor was coughing a bit but wouldn’t start, so I took apart the carb and cleaned all the valves and such out. Now, the motor is running but...

    Do I need a new stator?

    Been working on a 1983 Mercury 9.8hp with no spark on either cylinder. I did Stator resistance tests, and the resistance was within the specs for one of the stator-coils but not for the other (the other one was off-the-charts too high). Does this suggest I need to replace the entire stator? Is...
