I am looking for some assistance. I just purchased a 1999 215 Express Cruiser and the temperature gauge didn't work. I replaced the temp and alarm sensors with NAPA sensors, and the gauge started working and maxed out @ 220. I then replaced both sensors with OEM Mercruiser sensors, and the gauge still maxed @ 220. I replaced the gauge with OEM Sea Ray gauge and still @ 220. What can I replace next in order to get the gauge to read correctly? The manifold temp is 125 with a heat gun so I am comfortable that the engine is not operating at a high temp. Thanks for the assistance.
