Mercury – Thrust Holder | Propulsion & Mounting Components | Marine Alloy Finish | 8M0143215

Overview

Anyone who runs small outboards knows how much character they have. They may be compact, but when they are dialed in, they push a skiff or dinghy with a confidence that feels bigger than their horsepower rating. A tight, steady prop setup is part of that magic. The Quicksilver 8M0143215 Thrust Holder gives you that same sense of certainty you get when everything on the boat just feels right — no rattle, no hesitation, just clean, consistent power every time you throttle up. It is a simple part, sure, but it holds an important job in the heart of your propulsion system.

Performance & Practical Benefits

When you spend time navigating tight channels or running upriver with a light load, you can feel every little detail in how the engine responds. A secure thrust holder keeps the whole propeller system feeling tight and true, especially when shifting or powering out of a turn. You will notice how the boat tracks smoother and how the engine feels more connected to the water.

This reliable part helps prevent unnecessary wobble or slippage, which means more precise maneuvering around docks, sandbars, or shallow flats. It also boosts long-term durability by reducing stress on the propeller shaft and related hardware. Over time, you will appreciate the steadiness it brings — less vibration, cleaner thrust, and that small but satisfying sense that your outboard is working exactly as it should.

Installation is simple and straightforward, and once it is in place, you will hardly think about it again. That is exactly what you want from a core component in your drivetrain: set it, trust it, and get back to enjoying the water.

Why Buy OEM

An OEM Mercury Marine part is designed with the same engineering tolerances your outboard was built around. That means the fit is exact, the materials hold up season after season, and the performance mirrors what the factory intended. Aftermarket alternatives might look similar, but they often miss the mark on sizing or strength. With Quicksilver — the supplier behind Mercury Marine parts — you are getting years of testing, proven reliability, and the peace of mind that your engine is protected and performing properly. It is the practical choice every seasoned boater makes.
