    Default Nissan ns70c flywheel magnets

    I have a '99 NISSAN/TOHATSU NS70C 70hp 3-cyl outboard that has thrown and destroyed the magnets under the flywheel (FP6496,3F3-06091-2, magnet #361062902M) and am looking for a replacement flywheel, magnets, a flywheel with salvageable magnets without success so far. The "pan" is 136 mm dia. and 38 mm deep, the magnets appear to be 7 mm thick. The original magnets were held in place by magnetism and a bead of glue along the edge which according to TOHATSU fails on all old motors. There are three magnets with maybe 10 mm separation between them. Does anyone have any experience with a possible replacement for magnets or flywheel? Does anyone know of another make flywheel that would fit? Or another 3-cyl engine that uses the three magnet magneto system?

    This engine probably doesn't have 40 hours on it and any information that would get this outboard running again would be greatly appreciated.

    shocked you have not had any replies.
    lots of people race the tohatsu motors of all hp ratings.
    maybe have to ask on a Malaysian site, they race them big time....

    Apparently no one wants to be helpful or can't? So far everything I have tried has failed. No salvage parts. No NOS parts. No replacements. No alternatives. Anyone want to bid on a "parted out" 3 cyl 70 hp NISSAN?

    I'd try sourcing another flywheel from the wreckers and see if you can get some better epoxy or something to glue the magnets on better.
    Or maybe ask about it on a thundercat facebook page

    I have had the same problem happen with the same engine except a 1998 Nissan 70hp. It's on a sailboat and also didn't have many hours.

    Did you have a solution? Did you check to see if there was a recall on the motor?

    It was 2017, if he didn't find a solution, he never will. You could glue some neodymium magnets under there and have it re balanced.
