In some cases during transom repairs the engine can drop a small amount. This happens when the drive shaft is pulled out the engine hub. After installing new gimbal bearing the engine alignment tool may be required to line up bearing and engine hub in transom assembly. Boats that have soft stringers, were the engine mount has dropped down will require adjustment. Shims will be required to bring the engine mounting brackets back up to the original position. Engine drive shaft should then slide into new bearing and engine hub.
