Hi Chuck
I recall reading in one of your C&C posts that you have an M4-30 and that you dismantled and cleaned the heat exchanger. Is that correct and if so what did you find inside? I mean how it’s built and was anything clogging it? Also did you ever do any cleaning/maintenance where the salt water from the heat exchanger enters the exhuast gas line? My M4-30 runs great at 1600 rpm but when I run it at higher rpm’s it runs hotter than I think it should, like at 2500 rpm the temp gage climbs to boiling and sometimes 220 F but the engine is still smooth and strong, just hotter than I would like to see. I would like to see more water exiting the boat and I know my raw water pump is good since I have installed a new impeller with no noticeable change in performance and I know the raw water feed to that pump is not blocked, lots of flow into the bilge when I disconnect it from the pump. Can yo give me any advice from your experience.
