That 23+3=30 is fuzy math.

I have an I/O on the Elite 180. The front engine mounts to a plywood incapsulated base attached with wood screws. By the way when the wood screws turn freely Dont take any long offshore trips. Water gets down through the screws and rots out the base. Then the motor drops to the bottom of the boat. Then the engine gets out of alighnment and eats up your coupler. Then you pull the motor out and put in a new base. We used a high density foam and sandwiched about 10 pieces like a loaf of bread. We then put an aluminum plate on the top and glassed in the whole thing after tapping the aluminum. Should be a permanent fix.


I am sure not an issue on the outboards.
