Hello All;

Has anyone used a circulating pump system to run de-scaling solution through their heat exchangers to improve efficiency?

I have a persistent overheat at high throttle on starboard that corrects after reducing throttle a bit. I have been suspecting the heat exchangers as being kinda gunked up.

Initially I was looking at this as a kit:

But then they're out of stock and it doesn't look to terribly difficult or costly equipment to source myself. They're also available as 'tankless water heater de-scalers' on amazon for much much less.

Thinking this might be an easier solution than the whole dissassemble/boil with acid/reassemble bit.

Thoughts encouraged.
