Regulator Rectifier for Johnson/Evinrude 173692 583940 581778 582304, GLM 72350, MES 1781M - Sierra

The yellow wires can be installed in any order... makes for super easy installation. My motor charges great now. Idle is about 13 volts, driving down the lake it's 14.5 of higher... charges so well i am thinking of installing an isolator to charge my trolling motor battery with it between fishing spots.

Put it on and it works. It was a perfect fit.

the parts fit perfect and took care of the problem

After 8 years of being told that my boat didn't have a charging system, I find it just had a bad rectifier. Got this one and it charges.
