Overview

There’s a certain comfort in turning the key and hearing your Yamaha fire up without hesitation—no grinding, no sluggish turnover, just a clean, confident start. For boaters who spend long mornings chasing calm water or late afternoons riding back with the tide, that reliability becomes part of the rhythm of the day. The Quicksilver 8M6007429 starter is built for exactly that kind of trust. It’s the kind of part you install once and don’t think about again, because it simply does what it’s meant to do—every time you head out.

Engine & Boat Compatibility

This Quicksilver starter is compatible with:

Performance & Practical Benefits

The first thing you’ll notice with the 8M6007429 installed is how tight and smooth the engagement feels. The gear reduction design delivers strong, steady torque, helping your engine spin confidently even on colder mornings or after long periods of sitting. This stability is especially noticeable when you’re offshore or operating in chop, where dependable starts matter most.

Its construction is clearly tailored for marine life. High-temperature epoxy helps protect internal windings from moisture and corrosion, while the bearing and bushing design keeps the rotation clean and secure over years of use. It’s the kind of part that makes your whole setup feel more solid—like a handshake from a friend who never lets you down.

Installation is straightforward for most boat owners, thanks to its direct-fit design and compatibility with original Yamaha mounting points. Once it’s in place, it becomes one of those components that quietly improves the boat without calling attention to itself.
