Should You Buy This Used Stainless 3-Blade Propeller (14 1/4 x 21)?

This used stainless 3-blade propeller (14 1/4 x 21, part 389923) comes with some uncertainty, but the price is concrete. Here's what to weigh before buying.

Last updated Aug 17, 2026

Choosing a propeller for your boat often means weighing size, material, and budget. In the marine steering controls propellers category, a stainless 3-blade like this one can look like a smart shortcut. But when the seller says the part came from a storage unit and that they don't know its specifics, buying becomes a calculated risk. Here's what to consider before you commit.

Quick Verdict

If you know you need a stainless 3-blade in the 14 1/4 x 21 size, this used listing gives you a concrete choice at $129.95. The lack of history is the trade-off, so it's best for someone comfortable inspecting a used part on their own.

Who It Suits

This listing suits a hands-on boater who understands propeller sizing and doesn't need a seller to explain the part. If you're replacing a worn propeller and recognize the size, the stainless construction is a solid reason to keep reading. It's less ideal if you're new to boat maintenance or want a part with documented background.

What Stands Out From the Listed Details

The key details are straightforward: a stainless 3-blade propeller with part number 389923. Stainless steel is a durable material for a propeller, and the listed price is a concrete number to weigh. The seller's note that the item was obtained from a storage unit and that they are unfamiliar with any specifics is the key detail. You're buying the physical part, not a story.

Meaningful Trade-Offs

The main trade-off is the unknown. A used propeller can look fine in photos yet have damage that isn't visible. Because the seller says they can't provide specifics, questions like exact engine fit, prior use, and any repairs remain open. A buyer willing to inspect the propeller closely could find a solid deal, but the uncertainty is real. If you can't physically examine the part before buying, the risk is higher.

This used stainless 3-blade propeller gives you a 14 1/4 x 21 size and the durability of stainless in one part. The concrete limitation is the seller's lack of familiarity with the item's history, which means you take on the risk of hidden issues. It's a reasonable pick for a buyer who can evaluate the part firsthand.

Bottom Line

The Stainless 3 Blade Propeller 14 1/4 X 21 Boat Motor Propeller 389923 makes sense for a specific kind of shopper: one who knows the size, wants stainless, and is willing to assume the uncertainty of a used part. At $129.95, it's a fair gamble if the condition checks out. For someone who needs documented history, the unknown is a good reason to pass.
