Recently I saw quite a few posts regardig overheating,Well today I decided to start up the Evenrude 225 VRO.fortunately I made myself a running tank out of a 200 litre drum,Now my motor had not been run for a while because we are now at mid winter.
I filled the running tank with water and started the motor I was only able to monitor temperature by using a multimeter and temperature probes. the motor run well and showed no signs of running hot at all I then decide to flush the motor using Salt away and muffs, I noticed that the temperature rose much faster and the temperatures were 15 to30% hotter on the muffs,this indicates to me that muffs and a hose pipe are unable to supply enough water to keep larger motors cool even at a idle. If I left the motor running longer on the muffs the motor would have overheated,so as far as I am concerned true temperature readings cannot be obtained during the running of a motor on muffs.
kind regards William Wright
