Evinrude overheating question

Thanks guys, I have the test procedures for the stator from the manual, will check that out tuesday evening.

I’ll also check the carbs, air, fuel and spark right?

I enjoy working on the motor but some of the electrical gets beyond me.

You compression and spark. All you need is fuel. Carbs. Pull 'em and clean 'em. On an OMC of that vintage, carb cleaning is regular maintenance.

re water supply on muffs, just make sure you have enough flow that some is running out from around the cups. That way you know the passages feeding water pump are full.

if you have good spark on all 3 cylinders, it cant be a stator or any other electrical issue, unless you have the wires from the powerpack crossed, causing a timing issue.
sounds like fuel to me
and you probably need a carb job

Thanks, I’ll check the powerpack wiring, havent moved any wiring around other than the plug wires. Carb cleaning doesnt look to bad according to the service manual, I’ve done harder. :slight_smile:

Ok, thanks to the geniuses on here I pulled the carb bowl drain plugs. First the fuel lines, fuel flowed freely. Then the bowl drain plugs, top carb,fuel flowed, center and bottom carbs, no fuel flowed. Looked at them, thought it through, took pictures and pulled the bottom carb off. Everything inside was extremely clean, pulled the bowl off and found the needle valve stuck shut. Freed that, used carb cleaner to make sure the low and high speed orifices are clear and reassembled. Ditto on the center carb, pulled, found stuck needle valve, etc etc. Reinstalled everything, the inside if the carbs were amazingly clean, no evidence of old fuel at all, gaskets in good shape, all good.

Question though, the fuel lines had like plastic wire ties on them instead of metal hose clamps. I need to replace those, what kind to use?

Everything else looks good, will install fuel line clamps tomorrow and fire it up to see what it does.

Thanks for all the advise!

zip ties

Regular zip ties?

Zip tied em up, reassembled everything. Put gas to it and fired it up, all 3 cylinders running but the idle on my tester is around 1200-1400 rpms. Manual says the carbs have no adjustment on them and I didnt see any either. Any idea on the fast idle?

they make a special zip tie for fuel lines
they have a radius on the head to keep the hose pinched tight against the fitting

there is idle adjustment on that motor

I see a screw on the side that seems to limit movement of a lever thats connected to the shifter cables? I tried backing that off to the point it wouldnt make contact but it didnt make a difference. I’ll scour my service manual and see if I missed something tho, Ive been studying that thing for weeks it seems.
Thanks Chris V, I do appreciate the advice and suggestions.

idle adjustment is made by adjusting the timing

yeah . . . its going to the mechanic next week, a mans got to know his limitations :slight_smile:

Thanks Chris!
