hello all,

im having problems starting my evinrude 50 its an old engine but runs well once going.

last week went to mooring nice and early for an all dayer set every thing up for starting turned key heard fly wheel turn nice and quickly but by 3rd -4th turn started to slow down as if battery was flat.
got another batt not new from mates boat tried that same thing happened,decided to charge our batt for an hour to see if that would work.
after an hour just chhanced turning the key on the borrowed batt,started straight up??????.
after a days fishing starting and stoping engine going to different marks,no probs.
when we got back we had to wait an half hour for the tide .
once again bloody thing wouldnt start same as before.

its an old engine 1982 but i dont think there can be that much wrong as when running its sweet good tell tail flow and nice and quite.
could this be a battery problem?
mabey spark plugs anyone know the setting?
please help as i would like to do the things that i can do before calling in the ohh might have to replace that mate need a new one of these mate thats gona cost ya mate,man in.

cheers all

Ensure all the heavy leads have a good clean connection, worth remaking them with a smear of vaseline on the tabs. Battery and engine ends.

Try that first before you get complicated, if it doesn't work shout for more help.

hi chris

when you say remake do you mean replace with new cable or just clean and vas them.
ps how do i know if my engine is charging my batt not even sure if its got an alternator.

have you seen engines start like this before.usualy takes 5 mins to start after loads of slow turns of the fly wheel, then will suddenly start, thats whats making me think plugs????

sorry about all the questions mate.

under the ignition key there is a small knob which screws in and out slightly but doesnt actually come out,any ideas what this is :confused:

Loads of slow turns indicates a bad connection on the battery lead side. Turn the engine over and feel if any if the connections are warm. Corrosion equals resistance so they will get hot if corroded. Just clean all the connections between battery and starter motor and remake them, especially any you found were hot.

The small screw type thing could be a adjuster for tightning or loosening the throttle lever or some type of idle adjustment screw.

You can check if the engine is putting out a charge with a multi meter set to DC Volts. Check the battery voltage before you start the engine. Then when it is running check again the second reading should be higher than the first and in the region of 14 volts give or take.

hi des
welcome to the site mate try posting your question as a new thread youll get more responce.
many size engines will push your boat alot depends how quick you want to go and also depends on your hull type as to how fast you can go..also alot depends on how much £££ you want to part with

cleaned and vased all lead ends found loose earth thought id solved it no joy still the same.
the cable between the starter and the solinoid(i think thats what is is)gets hot and smokes a bit at the starter end after turning over a few times.
ive put new plugs in cleaned all the terminals.

whilst trying to start, it was turning over slowly.then on one turn of the key the fly wheel span fast as i would expect it to didnt start though.tried again slow turns again. :(

take the starter motor to. just alternators and starter motors at park gate.the owner will check it out for you while you wait.it may be the starter motor shorting out. the shop above is really good and they are cheap.
hope this may help m8 ;)

the starter may be drawing too much out of the battery when its cranking so there is not enough to fire the coils
