Saw this on amazon. Has dual temp gauge so you can do what @Scottie has outlined for us above but with a single 2" gauge.
Also comes with 2 temp senders.

That's a GREAT find. I may have even gone with that if I had seen it. Wiring harnesses included, should be a very easy install. I could free up a hole for another gauge at some point. I wonder what else would be useful?
Does not take long for t-stats to open on MR-1 engines. This can be confirmed by the extra exhaust cooling water port on the jet.
I think the higher rpm increases the exhaust gas pressure which forces the water out the indicators (pee holes). Acts as back pressure against the hose.
