The engine was mounted using the blind holes, and has been that way since I mounted the engine in 1985. That is old school using the blind holes as the motor cannot be adjusted up or down using that old method. That method is no longer used. All motors since the late 70's uses the Standard BIA mounting hole pattern. Here is how a motor should be setup for the correct height. http://www.veradoclub.com/smf/index.p...opic=137.0 Perry, Layout the Green holes (mark them with pencil) 6 1/2 inches from the top hole on your transom. See where they fall on the inside of the transom. Where are your top holes? 1 7/8" or 2" down from the top of the transom? Also measure and layout the 7 1/4" Yellow holes. See where they fall on the inside of the transom. http://www.whalercentral.com/articles...icle_id=82 Let us know if it is possible to drill the Yellow holes.

The engine was mounted using the blind holes...The cavitation plate is one inch above the bottom of the hull while the engine is in a vertical position (at the correct height) and the engine sits on the transom as well. No, the anti-ventilation (cavitation) plate is about one inch below the bottom of the hull.
