The motors --------WITHOUT ----------power trim and tilt did not have a voltage regulator. Just a rectifier.

the rectifier should be a round thing about the size of a quarter mounted on the side of the block....probably the left hand side as viewed from inside the boat....this is a known problem with high voltage out of that regulator with modern batteries....you should not run a maintenance free or a gel battery with that engine....the fix is to replace the rectifier with a regulator...maybe someone will jump in with the part number for it as i dont have it....the rectifier will eventually fail and the first indication will be a cutting up tach along with the voltage reading....the problem will also occur with a normal battery if it is rated too high for that engine.....the good marine battery from auto store for instance....you may get away for a while by increasing load on the battery...running lights or a 12v cooler for example..
