I am having an issue with the TNT, when the engine is running under load I cannot use the trim button on the throttle to trim up and down. I need to do into neutral then it works fine. ASny ideas where to start looking for the issue?
Make sure all the wire connections are good.
Check fluid
Check to see if motor is strong enough to power when the motor is under a load.
Is the trim switch in the side of the control handle? If so I would either try going slow or put boat on the trailer (and of couarse engine off) put in gear and see what it does. It may have a pinched wire??
