    Does the switch box impact the rev limiter?

    The rev limiter should be set at about 5500. 5250 is the top rpm of the motor to prop for.

    Does the switch box impact the rev limiter?

    Do you have the factory manual for your motor? Pretty sure that motor can run without the Rev limiter attached.

    1993 9.9 hp/15 hp power head to 1991 15 hp bad powerhead outboard.

    By the time you get done doing that you could buy a whole other motor. Look on Craigslist 9.9. Motors go for cheap

    Does the switch box impact the rev limiter?

    Pretty sure only the jet models of that motor had a rev limiter and it was a separate module.

    1993 9.9 hp/15 hp power head to 1991 15 hp bad powerhead outboard.

    No. Recoil and everything else are different. You need a 74-92 powerhead.

    Is the knob on the front of the motor turned all the way to the right? Is this motor new to you? And stop revving it in neutral on muffs.

    '78 Johnson 75HP will not return to idle.

    One gear ratio is for a short shaft One gear ratio is for the long shaft. The long shaft is MUCH more common. All the long shafts use the same ratio regardless of horsepower. The short shaft uses a completely different lower unit, with a different gear ratio. Good luck with your motor

    '78 Johnson 75HP will not return to idle.

    Highly doubt you have a factory manual. Difference between a 75 and 70 in the 49 cid block are porting and the head. Bore and stroke are identical. In 1986 the 70 hp went to the 56 cid block. The 75 stayed on the 49 cid block. Buy a good manual. The short shaft motors had different lower units...

    '78 Johnson 75HP will not return to idle.

    Doubt the 85 lower unit is a 15" lower. All the 3 cylinder 20" motors used the same gear case 78-87. Don't know how a gear case will make a 75 hp run better. The 15" mid section used a much less Robust lower unit. Not worth using for the average person.
