Re: hydrofoil or trim tabs or both??
Your SE 3000 probably isn't the best option (tool), but it may help.
The problem with most foil installs is that people think it's a bolt on and head to the water product...and it's NOT. This is where 90% of the complaints come from, they bolt it on, head to the water, and then it handles funny or they lose top speed. Well of course it will, you just bolted a large devise on your motor that when used incorrectly, or if not needed, will do just that.
A foil should not be dragging in the water at speed when set up correctly, on an outboard you can easily raise it up, on an I/O you just need to live with the possible negative side effects if you like the other things it may do.
A foil is not designed to do what trim tabs do, at least not in the same way. What a foil does is allow you to raise the motor higher and not let it ventilate, that's it, it is not supposed to drag in the water and force the bow down, although they do get used in this way.
What it can do, that is if your boat, motor, prop and type of use can even benefit from one is.
1 Allow you to raise the motor higher and not have the prop ventilate.
2 Less bow rise due the motor being higher up and having less leverage on the boat.
3 higher top speed due to the motor being higher with less gear case in the water.
4 better MPG from less gear case drag from the motor being higher.
5 possible prop change for even better performance.
6 Possibly better handling.
There is also the possibility that there will be no benefit because your combination can?t be helped by a foil.
Possible negatives if you don't do the set up work.
1 Loss of top speed due to the drag of the foil.
2 Odd handling, sometimes even scary due to the foil dragging in the water at speed.
3 Fewer MPG due to the drag of the foil.
