A string will be easier than a straight edge.
I'll look into that. I don't feel that's the issue since over half the engine is supported by the trailer but I'll rule out what I can. It's in the water now I'll check it next time it's outI know its an I/O, i.e. not as much weight on the transom as an outboard, but old aluminum hulls are known to "hook". This is where there will be a bend in the hull at the back downward usually due to not being properly supported by the trailer at the stern. Put a long straight edge against the bottom and check. Doesn't take much to make a difference.
Depends. Sometimes its engineered it to correct a bad hull design. But in most all cases it can be fixed... but how much time and or money do you want to spend on it?If it is a hook it it fixable or you just manage to it?
Actually a I/O is going to put a lot more weight in the stern than a outboard . 5-600 lbs vs 3-400 . The I/O is located about a foot from the transom . If trimming doesn't help you needs weight up front or some sort of tabs on the transom . I would stick with the 17" and if it's SS I might consider going to aluminum, that would up the rpms a bit . Or hit up a prop shop and have them bend you up a 16" prop .I know its an I/O, i.e. not as much weight on the transom as an outboard, but old aluminum hulls are known to "hook".
