Friends and colleagues..recently i wandered many and collected lots of scraped machines in to cars, helis, aircrafts and lots more..most of the machines are equipped with ECMs, but my intention to use all such ECMs on boats...but over heating is a problem with ECMs..so i tried to coll it with usual water scoop and extra pumps on it..but all it took extra power and space..so i found a simple remedy by adding a simple heat sink on ECMs...it works well...here is a ECM, is 4200 Rpm at Volt..heats up quickly..but after adding this attachment it worked perfectly...

find an appropriate heat sink, from a computer power supply, or can buy such heat sinks for Rs 10/- from an electronics shop..

after marking and drilling , remove any extra fissures..with flat file..apply a little electronic heat sink compound, and screw the motor firmly...now can fix it in any craft..and no worry of over heating...have many nice crafts...
