Harry,

He has a Yamaha 25hp outboard long shaft (20") for a 20" transom. His
Carolina Skiff is suppose to be for a 20" motor but when he hangs it on
there, the cavitation plate it is actually 2.75" below the bottom of the
boat. We run in shallow water and would like to have it mounted as high as
possible.

His manual says that the cavitation plate/disc should be either even with
the bottom of the boat or 1" below.

We were looking for an easy/cheap way to raise his motor 2.75"?
