10 TRAILER JACK TIPS
Use these maintenance tips to prevent your marine trailer tongue jack from failing prematurely: • Always retract the jack so that the inner tube is at least halfway into the outer tube before attempting to move your boat around.
When the inner tube is exposed, it’s not supported by the outer tube. This will cause premature failure of the lift mechanism. • Lubricate the moving parts of the jack and its outer surface with a waterproof lubricant like silicone. If your jack has a grease fitting (zerk), lubricate it with waterproof marine grease.
• If you store your boat on the trailer, place a chock or board under the dolly wheel. This keeps it from sinking into the earth or pavement and deforming as a result.
