Why choose Quicksilver
The Quicksilver brand has delivered uncompromising engine oils, parts and accessories to the marine industry for over 65 years. It is a premier supplier of Mercury Marine Original Equipment replacement parts, oils, and accessories, and also serves other OEM brands in marine and powersports. The result is a line built for durability, backed by extensive testing, and designed with performance and protection in mind.
While no single part guarantees outcomes, selecting an OE-grade thermostat can help keep cooling on track, potentially supporting smooth engine behavior and efficient operation across adventure and work days on the water.
Installation and care
For best results, refer to your owner's manual or service manual for the exact steps to remove a non functioning thermostat and install the new one. The kit includes the necessary gaskets and two thermostats, making it straightforward to complete the replacement with the engine cool and ready. After installation, recheck the cooling system for proper seating and leak-free seals, then run the engine per manual guidelines.
Practical notes
Consider keeping a spare thermostat on hand for scheduled maintenance, especially if you operate in challenging marine conditions or long sea trips.
