How to install water pressure gauge tohatsu m40c?

[niki12]

Hello, I want to put the outboard engine gauge water pressure.Can be installed on Flushing plug?

I tried it. I didn't read any pressure on a gauge with 35psi max. I currently have a tube running to the cockpit to monitor water flow. I need about 3000 rpm to get any flow to the end of this tube. So, very low pressure here, maybe very low pressure in the system. I've searched for a gauge with a low max psi, but haven't found one.

Look at tire pressure gages and adapt the gage. Many of them have a pressure gage that crew into a 'handle' and can be removed.
