Trim issue under throttle


New Member
Hey y'all,

New to this forum; need some help

1992 VIP 185 Fish & Ski with 2 stroke V6 Mercury Blackmax XR4 150hp outboard

When I advance throttle past half way point, trim automatically drops down and wont come back up. At slow speeds, sitting idle, on the trailer, etc., trim goes up and down without any issues. Happened for the first time yesterday afternoon. Anyone else ever have this kind of issue?
