Not sure what you can get for it,but my 23 Tsunami came with the same exact engine,and strangely it was also a Great Lakes boat(lake Ontario).It was in poor condition,never winterized,The freeze plugs were blown out,block looked ok but i never started it.
I sold the engine in as is condition for $450.00,and sold the 4bbl carb off it for another $95.00.

If i sold this engine in this shape,you should be able to do ok with yours as it's in good shape.Don't give it away cheap.
I fish the Great Lakes,and there's always guys up there looking for motors like yours.It might be a good place to advertise it.
