Greetings from Oregon. We have a Side Power SE60 bow thruster on our ‘97 Nordic Tug. I diagnosed and replaced the Thermo Switch back in late ‘21. It’s needing to be replaced again - almost three years to the month. Is this the lifespan? I see that our local parts distributor has 10 in stock - perhaps that’s an indication? Is there anything I can do to extend its life or is this one of those consumable parts we should keep as a spare? Jason Resch Hot Sauce 32099 Scappoose Oregon
