I have a 900 Merc. (1978 I think, can't find a way to confirm)That I can't figure out the way to hook on to the tilt pin without physically muscling the motor into a hole position. There is a clamp that will let it to tilt away if it strikes something but no way to just tilt it into position when preparing to launch. Some ramps let the rudder fin on the bottom of the lower end to drag before it floats. There is no tilt button that I can find. New owner and still learning. Thanks
