Frequently Asked Questions
-
Repack bearings annually or every 10,000 miles with marine-grade grease to prevent water intrusion and seizing. Check for play or heat after each launch.
-
Hubs are sized by axle spindle (1-1/16", 1-3/8", 1-3/4"); match brake type (electric/drum/hydraulic) and bolt pattern (4/5/6 on 4.5-6.5" centers).
-
Transom savers, tie-down straps, and fenders protect hulls during towing; LED light kits ensure visibility, while bunks/rollers reduce launch friction.
-
Use bow/stern straps rated for 2x boat weight, cross-strap hull sides, and check bunks for even weight distribution to avoid stress cracks.
-
Choose 1,200-2,000 lb capacity for tongue weights up to 10% of trailer GVWR; crank or A-frame jacks for easy boat positioning.
