Solas MGRNT Mercury Bravo III Nut Rear #81141172
$22.64
$25.88
Solas 81141172 Propeller Accessories
The rear prop nut on a Mercury Bravo III counter-rotating sterndrive is the fastener that secures the rear propeller on the outer shaft. It's a small part with a critical job. If it's lost, damaged, or corroded beyond use, the rear prop isn't going anywhere it's supposed to go. This Solas MGRNT rear nut is a direct replacement designed specifically for the Mercury Bravo III drive configuration.
The Bravo III uses a counter-rotating dual-prop setup, and the rear nut threads onto the outer shaft to lock the rear propeller in place. Getting the correct nut for the rear position matters because the Bravo III uses different hardware for the forward and rear prop positions. This is the rear-specific part.
It's an inexpensive piece of hardware that's easy to overlook during a prop service, but having the right one on hand saves you from a delay when you're mid-job on the water or in the shop.
Fits: Mercury Bravo III sterndrive
Position: Rear propeller nut
Application: Secures rear propeller on outer shaft of counter-rotating drive

Solas 81051341 Propeller Accessories
The Solas YD-SP2 81051341 is a precision-engineered propeller spacer designed specifically for Yamaha outboard engines ranging from 60 to 100 horsepower. This essential propeller hardware component ensures proper propeller positioning and alignment on the propeller shaft, maintaining optimal clearance between the propeller and the gear case for safe, efficient operation.
