Stern drive usage
« on: January 10, 2010, 02:22:29 PM »
Hope I'm not bugging you Brian but I thought of another question. When using a stern drive (I/O) with the Great Alaskan, will there be a dog house protruding above deck level or is there enough hull depth so the deck will be flush against the transom?

I used to be indecisive but now...I'm not so sure.

Built exactly as specified, there is 27-5/8" from the top surface of the deck to the top surface of the sheer deck right in front of the transom.  Unless you choose a particularly tall unit, there should be no reason for the stern drive motor box to end up higher than the sheerline.  Example:

Cummins/Mercruiser 170-200 hp sterndrive is 31" from bottom of oil pan to top of motor.  It is 20" from bottom of motor mount to top of motor.  Given the mounting specifications, the motor mounts will be just below the top of the stringers.  The top of the motor would be at about 19" or so above the deck, so you have an extra 8" or so above the motor for the top of the box (and insulation).  I think you'll find this motor to be fairly typical.
