The temp sensor connector was starting to fail on my M25XP. The wire was breaking and it would barely hold on to the button connector on the sensor. After a few days of research I found a few temp sensors for GM sensors that looked the same. Westerbeke is known for using automotive components so I gave it a try. Shipping was faster than expected. I received a high quality connector with pigtail from the listing below. It even features what appears to be high temp wire on it. The wire is a smaller gauge so a step down butt connector is suggested. I'm posting this as I'm sure someone, someday will also need to replace their connector.
