DABAZUALY Thermostat Kit 160° for Mercruiser GM Inboard/Outdrive 1987-2016

Overview

Designed by DABAZUALY, this Thermostat Kit 160° is crafted to support MerCruiser GM inboard and outdrive engines from 1987 through 2016. The kit centers on a 160-degree thermostat and pairs it with dependable gaskets and a plastic sleeve to help maintain steady cooling across a range of V6 and V8 configurations, including 4.3L, 5.0L, 5.7L, 7.4L, and 8.2L. The combination is intended to assist reliable cooling path sealing and consistent engine response during regular operating cycles.

Instead of a single component, this kit provides a complete package designed for straightforward service. By assembling the thermostat, sleeves, and gaskets together, you may experience a cleaner, more organized replacement process that aligns with MerCruiser service practices of the era. While outcomes can vary with application, the kit is meant to support proper cooling system operation when installed on compatible engines.

Usage and Benefits

Users may notice the kit’s emphasis on tight seals and proper flow through the cooling pathway, which can contribute to steadier engine temperatures during operation. The 160° thermostat is designed for standard cooling expectations on the specified engines, while the sleeve and gaskets help seal critical junctions during maintenance and reassembly. This set is not a guarantee of performance, but it is assembled to align with common MerCruiser service configurations and parts compatibility.
