Johnson J150STLCDC 1986

by Bill
(Florence, Al)

The tach stopped working and the battery not charging (only 12.5 volts). I replaced the regulator/rectifier and both problems were fixed. Tested the boat on water and gave a miss and it won't plane off. I checked all cylinders and they are all firing. I am at a loss for the correct diagnosis.

Any help or suggestions are greatly appreciated.

Thanks Bill E.
