When I try to raise my outboard with the rocker "up" switch on my control unit, it comes up about 1/4 of the way steady but slowly, seems to stall and stick for about 4 seconds, and then rises rapidly. It was, according to the prior owner, always this way. I can see a reason for this, as it gives you better incremental adjustment with the engine in use and the prop in the water, but I still worry about the time it spends making noise and doing nothing. A sticking point or a transition in control? Down works smoothly through the whole range. Is this normal?
