150 four stroke trim stop

Actually it doesn't do that. Adding the resistor just allowed me to trim to the 22 degrees that the Mercury specs for this motor said it would have. I was trimmed to 17-18 degrees to get the fastest speed. I don't want this boat to be unsafe or to break I just want it to do what they said it would do. Without countless hundred mile trips back to the dealer.

I was out in my shop testing voltages. 0 volts is all the way down and it looks to me to be about 1.5volts D.C. is when the trim shuts down. I'm not telling anyone to do this but it sure looks like a resistor can be added in series with the white wire to make it trim higher than it does now. The 3-wire triangular plug on the left side of the motor red +5vdc, black 0vdc, white wire is the variable 0-5vdc. I've got plugs exactly like that in my shop so would be simple to make up one that would fit right in there and also be able to be removed easily.
