My newly acquired 18' I/O skier had a custom ski post mounted to the floor and the front of the exhaust manifolds. I removed it and reinstalled the original reinforced aluminum post; to the floor and the 'bulkheads' on each side. This post is about 1"-2" above the motor hood top. On my 20' I/O skier it is at least 8" higher. Was the post height established on the basis that assumed it needed to clear outboard drives? Any experience with a low post out there?
