All Sierra products meet or exceed the original equipment part it replaces. Sierra supplies many OEM engine manufacturers and boat builders hundreds of quality parts every day Review: exact replacement - works great - a little pricey for what it is but it is an exact replacement for the originals which were no longer rigid enough to hold the button in. the new on looks and works great. Review: Pricy, but fits older Merc safety switches - Fits Merc-Style ignition safety switch that the 'universal' safety switch lanyards (with multiple switch style fobs on a lead) doesn't. When my original clip broke after many years of use, I went looking for a replacement. My boat has a MercJet and the safety switch requires a very tall prong to fit over the switch. I bought a couple of different 'universal' lanyards that have multiple styles and sizes of clips, but none of them fit my boat. This is the only lanyard on desertcart I've found that does fit. It's pricy, but still much cheaper than what the boat dealer wanted to charge. ## Features - Part number: MP40990 - Fit type: Universal Fit - Included components: Lanyard - Package Dimensions: 6.096 L x 17.272 H x 9.144 W (centimeters) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000AXMFA | | Best Sellers Rank | #184,515 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #122 in Boat Tools #304 in Restraint Ropes & Lanyards | | Blade Material | High Speed Steel | | Blade Shape | Rectangular | | Brand | Sierra | | Brand Name | Sierra | | Color | White | | Customer Reviews | 4.6 out of 5 stars 247 Reviews | | Global Trade Identification Number | 00808282367206 | | Handle Material | Plastic or Rubber | | Included Components | Sierra MP40990 Marine Coiled Lanyard | | Item Dimensions L x W x H | 3.6"L x 3.6"W x 6.8"H | | Item Type Name | Sierra MP40990 Marine Coiled Lanyard | | Item Weight | 1.6 ounces | | Manufacturer | Sierra | | Manufacturer Part Number | MP40990 | | Manufacturer Warranty Description | LIMITED WARRANTY | | Model Number | MP40990 | | Number of Items | 1 | | Number of Packs | 1 | | Number of Teeth | 5 | | Other Special Features of the Product | Adjustable | | Power Source | Battery Powered | | Special Feature | Adjustable | | Specification Met | Yes | | Surface Recommendation | Wood and Metal | | UPC | 808282367206 | | Unit Count | 1 Count | | Warranty Type | Limited Warranty | ## Product Details - **Blade Material:** High Speed Steel - **Brand:** Sierra - **Color:** White - **Power Source:** Manual - **Surface Recommendation:** Wood and Metal ## Images ![Sierra International MP40990 Marine Coiled Lanyard - Image 1](https://m.media-amazon.com/images/I/81bO+0NYKjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ exact replacement - works great *by J***. on April 18, 2023* a little pricey for what it is but it is an exact replacement for the originals which were no longer rigid enough to hold the button in. the new on looks and works great. ### ⭐⭐⭐⭐⭐ Pricy, but fits older Merc safety switches *by J***N on February 7, 2025* Fits Merc-Style ignition safety switch that the 'universal' safety switch lanyards (with multiple switch style fobs on a lead) doesn't.
