New Inboard Transmissions

A Quicksilver exclusive, 100% new mechanical transmission assemblies offer the best value on the market by delivering: INCLUDED rigging content worth over $1500, mounting hardware, fluid‑filled and factory tested. This means everything is ready to go to install a complete inboard using a bobtail Plus Series engine.

These new transmission assemblies include:
• Transmission mounting brackets, trunions and hardware
• Transmission mounts
• Heavy duty copper cooler
• Transmission fluid hoses
• Shift bracket and hardware
• Gear indicator switch
• High temperature switch
• Fresh coat of phantom black paint

The typical application is for MerCruiser, Quicksilver and Mercury Remanufacturing gasoline inboard engines. Engine couplers may need to be changed based on the transmission and application. In general spring plate couplers are used for inline or co‑axial transmissions, and dual‑stage couplers for V‑Drive and Down‑Angle transmissions. If using on an existing engine, a new coupler is recommended when using a new transmission.  Please be sure to install and properly adjust new premium shift cables as the #1 clutch failure is from improperly adjusted shift cables that can result in severe transmission damage. Propshaft couplers need to be ordered separately. 

Now available for the first time, quarts of Quicksilver marine transmission fluid. A special formulation of marine transmission fluid for heavy‑duty marine transmission use that exceeds Dextron II & III specifications. New OEM transmission oil coolers can be found here
