Boat mechanics and marine DIYers, this PMFCA spanner nut wrench is exactly what you need for working on MerCruiser stern drives! This tool replaces part numbers 91-17256, 91-36235, 18-9803, and 90100, so you know it's the real deal. Designed specifically for removing that 4-3/8 inch retainer nut on MerCruiser Alpha One, Pre Alpha, Generation 2, and Bravo One models (note: won't fit Bravo 2, 3, XR, or TR). The 1/2 inch socket drive works with your standard breaker bar or torque wrench, giving you the leverage needed for those tough marine fasteners. Made from high-quality materials that resist wear and stand up to the harsh marine environment. Whether you're doing routine maintenance, repairs, or installations, having the right specialized tool makes all the difference. This isn't something you'll use every day, but when you need it, you really need it. Much cheaper than taking your boat to the marina for simple jobs, and it pays for itself after just one use. Serious boat owners know that having the proper tools on hand is key to keeping your vessel in top condition, and this wrench is an essential part of any MerCruiser owner's toolkit.
