Don’t get a Chinese Copy they don’t work.
So while on my Monterey 340SY 2014 I was having some Weird Guardian Alerts Issues and one of the issues was a Bad Block Pressure Sensor on my mercruiser 350 MAG Engine. In this video I will show you how to figure out if yours is bad it’s easier if you have a Dual engine like mine so you can compare your starboard engine vs your port engine and if one is way off then it’s time for a new sensor. At first i got a Cheap Chinese replacement on Amazon but that still gave me issues so i purchased a Genuine Part and that fixed it once and for all.
