    90hp Merc 3cyl reaches 3000RPM but takes awhile to go over 3000RPM

    13.25X17 pitch prop have not changed prop and it’s not spun. 16’ smokercraft pro mag. Gear ratio 2.31:1 trying to find out what the ohm reading on the windings should be and where to put the leads to test. I’m pretty handy with things but no expert on boat motors.

    By the timing light I do have spark just not sure how strong it is under high speed load

    So I have a 95 90hp Merc 2 stroke. Not under load it revs no problem but under a load speed and RPM's quickly pick up to 3000 RPM no problem. But it takes 2 min or more to go above 3000 RPM, and will peak at about 4300 RPM. It should peak at 5500 RPM. Compression good 120 +-1 on all 3 cylinders...
