What you describe sounds pretty common for inboard engines. I wouldn’t change props to try to fix those problems. Any change in props will reduce your tip end performance, hurting either speed or efficiency. For me shifting in and out of neutral is just how maneuvers are done. Any engine that can produce decent top end speed is likely to move the boat way faster at idle than you would want to hit the dock at. Maneuvers should be a combination of forward and reverse to get the boat moving, and coasting in neutral to turn. You’ll likely also find that, especially in reverse, the prop walks the stern to one side or the other. Learn which direction it does and how to use it to turn the boat the way you want.Here is some more information about it. The SolidNav motor is inboard.
At the lowest throttle setting, the speed of the boat is too high. I need to keep putting it in neutral and only putting it in gear for a moment when trying to dock.
In open water, the boat makes about 6-7 knots at full throttle, and accelerates well.
But what is really a problem is that when the boat is moving very slowly, like when leaving the dock, deflecting the tiller to turn, especially when in reverse, the boat does not change direction.
I am having to use a small outboard motor for all maneuvers involving slow speed.
And a friend said that he thought the prop was cavitating, but I can't confirm this is the case.View attachment 189210
