Hull Protection & Propellers

Boat Hull Protection, Keel Guards & Propellers

Everything below the waterline takes the most abuse on your boat, from beach landings scraping the keel to corrosion eating away at your prop. CritPro carries hull protection and propellers built to hold up against real wear, as part of our full boating selection for boat owners who want their hull and running gear protected season after season.

What to Look for in Hull Protection & Propellers

Keel guards and hull protection strips need to match the material and profile of your hull, since a guard that does not sit flush can trap debris or peel loose over time. Look for UV-stabilized materials that will not crack or fade after a season in the sun, and make sure any adhesive-backed protection is rated for constant water exposure, not just splash contact.

Propeller material and pitch should match your boat's engine, weight, and typical running conditions, the wrong prop can cost you both speed and fuel efficiency even with the right horsepower underneath it. Sacrificial anodes deserve their own attention separate from the prop itself, since they protect your entire underwater metal system from galvanic corrosion and need replacing well before they are fully worn away, not after.

What This Category Covers

Hull protection and propellers at CritPro includes keel guards and hull protection strips, propellers and prop accessories, sacrificial anodes and zincs, and prop nuts and hardware. Whether you are protecting a hull that takes regular beach landings or replacing a worn prop, this category covers what keeps your boat running efficiently below the waterline.

Pairing Hull Protection with Other Boating Equipment

Boat owners protecting their hull and running gear often handle it during the same maintenance pass as cleaning, detailing, and protection work, since both are part of the same below-the-waterline upkeep. Our full boating selection covers everything else needed to keep the rest of the boat in shape.
