Patrick - You should check the mounting hole spacing you have on the transom.

I emailed you the measured drawing of the BIA standard pattern.

To mount the engine, I would start with the top bolt in the 3rd hole counting down from the top (assuming the top mounting hole is 1-7/8" (47.6 mm) down from the top of the transom.

When you raise or lower the engine it will affect WOT rpm's by 150 for each hole, plus or minus.
