I have a Yamaha 25hp 2-stroke (electric start, remote steering) on an LT15. Long story short, the motor will not lock in the down position except when the gear shift is in the reverse position. The rod assembly that locks the motor down works appropriately when the gear shift is in reverse, but does nothing when the motor is in neutral or forward. If I understand what I'm seeing correctly, I think the rod assembly is working appropriately because the lever to put the motor in shallow-water drive or completely tilted up should be what keeps the motor locked down, not something tied to the gear shift. Problem is, I can't figure out mechanically how the lever assembly to unlock the motor to tilt up into shallow water drive is supposed to keep the motor locked in the down position. Almost makes me wonder if something broke without me knowing it. Any ideas?
