motor trimming perameters

Question
cruising on my pontoon, my anchor fell off the front, came underneath and struck the propeller, tearing off the several blades, on repairing the propeller I could see no other damage. While cruising now, I cannot seem to get to the same speed as before. Engine is running great and I have on the same propeller type. Visually, I watch the motor and at full bore it seems to trim too far down, past 90 degrees. Is this right? or I am thinking that there might of been a pin to stop it from trinmming down too much.
I cannot figure it out.

Hi Eddie

Thank you for selecting the undersigned to reply to your question.

First of all, I'm surprised your anchor line was either thick enough or strong enough to fracture the prop's blades. So long as you're certain the pitch and diameter of your prop remains the same after repair, it would have no effect on the trim system. Achieving a particular speed is the problem, and it's possible there's some slippage in the propeller shaft, which will have to be explored.

As far as the angle of trim is concerned, the propeller has no effect. Consider where you're placing cargo, equipment, and/or passengers onboard, which can and will affect how the trim system reacts to the speed of the hull.
