Getting Your Boat Ready to Launch: Outdrive Maintenance

Bravo III Outdrive Corrosion 011
By the nature of their design, I/O’s are vulnerable to salt water ingress at the transom and especially susceptible to corrosion. Before your boat goes back into the water, you should remove the outdrive(s) and:
— Inspect the bellows and replace them if cracked
— Check the gimbal bearing for signs of wear
— Drain oil to check for evidence of water due to leaking prop shaft seal or water pump seal; replace with new oil
— Inspect raw water cooling system, checking impeller, cleaning strainer gauzes and removing salt and marine growth such as barnacles from water passageways; reassemble and paint
— Remove prop, inspect for damage and grease shaft
— Align and lubricate gimbal bearing, universal joint and drive shaft on re-installation
— Replace the zincs
