Hey there, boat owners and DIY engine folks! If you're dealing with a dodgy oil pressure switch, this one's a direct replacement for a bunch of popular brands. This little sensor is your engine's guardian – it trips at 6 PSI to trigger a low oil pressure alarm or even cut off the electric fuel pump if things get too low. Super important for preventing major engine damage, right?
We made it tough with high-quality materials so it can handle the marine environment. The specs are spot-on: 6 PSI trip point, 1/8-27 NPT thread so it screws right in, and a 10-32 stud terminal for your wiring. It's a normally closed switch, meaning the contacts close when pressure drops (to sound the alarm) and open when pressure's good.
Wondering if it fits your rig? It replaces Mercury part numbers 87-805605A1 and 87805605A1, Sierra OP22900, Marine Power 457045, Stewart Warner 364L-F, Penta 872065, and Universal 299964 or 97767. Perfect for Mercruiser, Volvo Penta, and a whole list of marine and industrial engines where you need a reliable low-pressure warning.
We're so confident you'll love it that we back it with a 1-year warranty. Got questions during install or just wanna confirm fitment? Just reach out – we're here to help you get back on the water safely and without that worrying oil light!
