Is work fine great price easy to install of course

Nothing wrong with this one, but I ordered the wrong one initially.Be sure you're engine temp sensor has 2 prongs and not one.There are 2 common types. For older models (specifically 5.7 Liter Indmar, 1996 EFI), the other one can be found here:https://www.amazon.com/gp/product/B00027GZ7I/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Works well

Exact replacement for my Mercruiser 4.3L Half the price of the boat store one.

Great

Good price but, as they say, you get what you pay for. Did an ohms test on this sensor when it got it. Merc book says 450 ohms at 160 degrees (F). The sensor was reading 425 ohms which means it will tell the ECU the engine is running hotter than it really is. I checked this on the temp rise & fall & it consistently read less ohms than the OEM spec. Still will give it a try & update this thread if I find unsatisfactory results.
