1988 evinrude 60hp

[mav6759]

I have a Evinrude 60hp 1988, thats has no power on the water but planty of power on the muffs. When I put a load on it or (put it on one of the local lakes in my area), the engine dies, when I have it on muffs, it runs perfect. Do anyone have any ideas as to what this can be.

check your compression, and spark. compression should be 100+ psi, and with in 10% of each other. also could be link n sinc.

Multicylinder 2 strokes will seem to have plenty of power with no load even when they are actually only making power with one cylinder, Mav. It is a lie that fools many a boater.

Check to see that all cylinders are making power. My guess is that one or more are dead.

You can do this while idling on the muffs by disabling each spark plug. If the idle does not change when you "kill" a cylinder, that cylinder is dead.

dead meaning, it is not getting spark, or fuel or low compression.

I check the compression on the motor, I was told that the compression was 110, 90, 60, I can take it that I need to rebuild this unit. I'm very new to this and very weak when it comes to rebuilding a outboard. What do you look for when rebuilding a motor with low compression. What do you change out on the motor.
