<h3>About Engineered Marine Products (EMP)</h3><p><strong>Engineered Marine Products</strong>, widely known in the boating world as <strong>EMP</strong>, has been a trusted name in marine parts manufacturing for over 40 years. The company supplies OEMs, distributors, dealers, and rebuilders worldwide with high-quality aftermarket components engineered to meet or exceed original equipment manufacturer (OEM) specifications. Whether you maintain a weekend fishing boat or a performance inboard, EMP&apos;s extensive catalog is built to keep marine engines running reliably season after season.</p><h3>A Marine Parts Specialist Built on Engineering Precision</h3><p>EMP&apos;s foundation is precision manufacturing. Their design and production processes leverage modern engineering technology, with a focus on dimensional accuracy, material quality, and long-term durability in the demanding marine environment. Salt spray, constant vibration, wide temperature swings, and moisture ingress are realities every marine component must survive — and EMP engineers its parts with exactly those conditions in mind.</p><p>The brand&apos;s catalog spans a remarkably wide range of marine engine subsystems. From cooling and fuel delivery to gearcases, propellers, transom components, and steering systems, EMP offers solutions for outboard engines from manufacturers including Mercury/Mariner, Yamaha, BRP (Johnson/Evinrude), and Force, as well as inboard/sterndrive platforms such as MerCruiser, OMC, and Volvo Penta.</p><h3>Ignition and Electrical Components</h3><p>One of EMP&apos;s most comprehensive product areas is marine ignition and electrical systems. Their <a href="/13199-engineered-marine-products-ignition-control-module-10488">Ignition Control Modules</a> and related ignition components cover a broad spectrum of inboard and outboard applications — from distributor caps and rotors for Volvo Penta V8 engines to ignition coil assemblies compatible with MerCruiser 3.0L through 8.4L GM-based powerplants and OMC configurations. Reliable spark delivery is critical to engine performance and starting consistency on the water, and EMP&apos;s ignition lineup is designed to deliver dependable output across the entire RPM range.</p><h3>Gaskets, Seals, and Engine Integrity</h3><p>Keeping a marine engine leak-free is just as important as keeping it firing correctly.

Product Details

The Engineered Marine Products 43-02786 Clutch Dog Spring is a critical component in marine outboard motor lower units, designed to maintain proper clutch dog engagement during gear shifting. This spring applies constant pressure to force the clutch dog assembly into the forward gear position, ensuring reliable gear engagement and preventing the clutch from slipping out of gear under load.

Key Features:

  • Provides consistent spring tension for smooth, reliable gear shifting
  • Helps prevent clutch dog slippage and gear jumping under load
  • Essential component for proper forward and reverse gear operation
  • Direct replacement for OEM part numbers 320311 (BRP) and Sierra 18-2398
  • Manufactured by Engineered Marine Products (EMP), a recognized producer of marine engine parts

The clutch dog spring works in conjunction with the clutch dog assembly to ensure the shift mechanism maintains proper engagement with the forward and reverse gears. When the spring becomes worn or loses tension, it can result in difficulty shifting, gear slippage, or the transmission popping out of gear during operation. Regular inspection and replacement of this spring during lower unit maintenance helps ensure reliable transmission performance and extends the life of other drivetrain components.

Unexpectedly rapid delivery. Extremely appreciative.

I wish would tell if it comes in pairs though!

First time using you guys. Hopefully your better then redline360. Bought a blox brake kit from them. Everything went on smooth. Then go to bleed and the bolt holding the bleeder snaps off. Spent 3 months. Sent back the caliper. Told me they would have a replacement mid june. Then they contact me telling me they are going to refund me. When that's what I asked them to do in the first place.

Easy enough
