Honda 135 HP engine shutdown-intermittent

I did check out the thermostat sensors and replaced one that appeared corroded after the initial shut down. Unfortunately, the engine shut downs continued.
Since arriving home and thoroughly checking out the situation per above, I have had no additional episodes. Ran the engines hard and erratically for several hours last weekend and the starboard ran perfectly.
Time will tell!

Ok thanks for the update.

Do you have a Honda shop manual? What is the SOP to check the sensors?
First check continuity ? Then place in water at different temps and check resistance?

I am surprised it didn't throw a code.

Maybe purchase an IR thermometer to check engine block temps
