Quicksilver 8M0101603 Flo-Torq SSR HD Propeller Hub Kit for Mercury 200-400HP Outboards

The Quicksilver Flo-Torq SSR HD Propeller Hub Kit (8M0101603) is engineered specifically for Mercury FourStroke outboards rated 200-400 horsepower with 1.25-inch diameter propeller shafts. This solid hub system incorporates Quicksilver's proven Soft-Shift Rubber (SSR) technology to dramatically reduce shift noise and eliminate the harsh "clunk" commonly experienced during gear changes.

Key Features:

• SSR technology delivers 22-23% reduction in shift event noise, virtually eliminating shift clunk
• Prevents shifting vibration, harshness, and propeller rattle for smoother power delivery
• Complete kit includes SSR drive sleeve, 3-washer set (standard washer, thick washer, and cupped Belleville washer), tabbed lock washer, and locking prop nut
• Designed for 200-400HP Mercury FourStroke outboards with 1.25-inch prop shafts
• Quick and easy installation with Quicksilver floating prop wrench and prop block or common shop tools

Important Compatibility Note: Mercury FourStroke outboards with serial numbers lower than 2B244273 require an updated engine calibration from your dealer before using this hub kit. For 40HP CT through 225HP outboards with 1-inch diameter prop shafts, different SSR hub kits are required depending on application (general purpose vs. high performance/surface piercing).

Backed by over 65 years of marine industry expertise, Quicksilver delivers uncompromising quality through rigorous testing and design. This genuine Mercury Marine OEM replacement part ensures optimal performance, protection, and peace of mind for your outboard investment.
