    J40ELCR WOT needs key pushed and released for full power

    carbs... of course ! "The guy actually cleaned the carbs for me after I bought it. Didn’t see him do it but he seemed pretty honest." spraying carb cleaner won't do it it needs a full tear down with all the intricate passages (orifices - jets- needles cleaned and air blown then adjusted...

    I did not read the whole book but I believe that at Key on the start assist circuit (SAC) should immediately get the HPP going giving you some semblance of available PSI,s regardless if the engine strarts or not. that said and you seemed to have sparks ...... fuel injection does not seem...

    melting indicates very high current draw across a resistive path P=R Xi Xi bad -flooded switches would likely not carry such high current and likely just blow the 10 amp fuse ... used to energize the low amp relay windings used to mecanically close and feed high current to the...

    1973 4hp Evinrude

    these 4hp do run hot ....so what is HOT ?? the exhaust cover is NOT water cooled like bigger HP models and they frequently become discolored. measure the engine PH with a IR heat gun to detect any true HOT spots

    1973 4hp Evinrude

    maybe I am wrong but I do not think you need so much sealer on the impeller housing and in any case where would air enter the pump if it is under water ?? these are as simple as they get engine wise.

    1973 4hp Evinrude

    millions were made and still run perfectly. nothing realy wrong with the design. if colling flow is a problem on your 4hp then there is blockage somewhere and needs to be found. pull the PH if you have to and flush all passages with a cleaning agent...or just soak passages with hot...

    and fuel pick-up filters etc...including deteriorated fuel hoses ..a high pressure test and lift pump pressuretest will determine if fuel makes it to the VST properly then the injectors then it becomes a . question of proper injector operation if not crudded up , ignition control by the EMM.

    EMM does not see everything it only senses things like current flow to some parts, sensor outputs etc... it does not see cracked coils dirty injectors bad fuel flows poor injector pressure etc... having no codes just eliminates a lot of things to check out. before swapping...

    you are correct the 1990-2001 does not go up to your engine size but the fundamentals are there. As to the other link it also contains basic info. your engine has the infamous PDP known for cold solder joints on the main B+ entry into the panel. not saying it is the problem mind you just...
