Re: yamaha 115 tilt/trim
If I'm reading this correctly, you are trying to operate in the Tilt range. They're made to do that. The two trim rams hold the motor at various trim angles. Above that the Tilt ram in the middle takes over. It's not strong enough to hold a motor under thrust. They don't want it operated up there anyhow. Steering gets strange, the water intakes can come out of the water, and the bracket is no longer tucked in between the lateral supports which could snap the swivel bracket.
