🚤 Sierra International 18-2917-9 Marine Thermostat Gasket - Pack of 2: A Reliable Solution for Marine System Performance Review

After trying this product on my boat's engine, I've been impressed with its performance. The temperature is well-regulated and the engine runs smoothly. The installation was straightforward, with no issues encountered. The only downside is that it is a bit pricey compared to other options on the market. Overall, I highly recommend this product for any owner of an automotive marine engine in need of a reliable thermostat.

Perfect fit and functionality. Has brass lugs to ensure electrical continuity between the thermostat cover and the housing.

Fits perfectly as a replacement for my '00 Mercruiser 5.7 liter thermostat housing but be sure to remove any old gasket residue. The dual bars on each side should hold the correct thickness of washer while tightening the case screws. No leaks.
