Overview

The Attwood Marine 11370-7 is a prop wrench set with multiple socket sizes for prop nuts from 17/32" to 1-1/4". It is made for routine propeller service, whether you are changing a damaged prop at the dock, swapping to a spare, or keeping one wrench set on board for general prop maintenance.

The size range covers a broad spread of common prop nut sizes, so this set works well when one boat, one engine, or more than one prop setup calls for different hardware. The composite construction keeps it light, and because it is not metal, it will not rust when it lives in a wet locker or gets used around saltwater.

Key features

• Fits prop nuts from 17/32" to 1-1/4"
• Multiple socket sizes in one set for propeller service across several common nut sizes
• Composite construction will not rust and keeps the tool lighter than a comparable metal wrench
• Floats for easier recovery if it goes overboard during a prop change
• Yellow finish is easier to spot on deck, in a tool bag, or in the water

Compatibility and fit

This wrench set is a fit-by-nut-size tool, so the main check is the size of the prop nut on your current setup. It is not tied to one engine brand or one propeller family as long as the nut falls within the 17/32" to 1-1/4" range.

That makes it a practical piece to keep with a spare prop, cotter pins, and basic service items on boats where quick prop work may happen away from the trailer or workshop. It suits owners who want one onboard tool that covers more than one common prop nut size without taking up much room.

Use on board

This set makes the most sense for boaters who handle their own basic prop service and want a dedicated wrench ready in the locker. It is a good match for trailered boats, small fishing boats, runabouts, and other setups where a compact prop service tool is worth keeping close at hand.
