Transom Bracket - twin outboards

[McGillicuddy]

I think John is dead on about the negative trim - you have excess and that need a way to govern that, wedges or a 2x4 - whatever keeps your prop shaft and cavitation plate mostly parallel to your keel. Like Dana Carvey mimicking Uncle George Sr., "Don't want to be \ nor / wanna be somewhere in between, sure..."

Fr. Frank's suggestion on measuring engine height is very important. Straight edge on bottom of hull in line with each motor skeg and cavitation plate parallel to hull bottom. Seacrafts run best with cav plate about an 1-1/2" above the hull bottom, additionally, Armstrong asks for 1" of rise for every foot of bracket setback...you do the math.

Finally, I'm with reelescape - ditch the foils. Use the the trim tabs for efficient planing and hull control.

Different props may help but I think the other three issues should be dialed in first. Good luck, and keep us posted.
