Transom Bracket - twin outboards

[lobo1]

neutral trim, the motors are in the second hole from the top - I used a straight edge and a level from the bottom of the hull, right under the drain plug....I measured to the cav plate just like in Bushwackers picture. 8.5 inches is what I get......my straight edge runs just about down the centerline of the lower unit - right thru the center of the prop.

Each hole only gets me one inch. I have one up and two down to work with- any ideas - now that you know what I have?

Sounds like I have a mess
