1991 evinrude 25 HP electric start -starter won't stay engaged

[rthalls]

my 91 evinrude 25 hp that I just purchase will not keep the starter engaged past the first compression turn [ had the starter rebuilt and still dose the same ] it has 12 V at the starter on cranking - the battery is good and also put in new starting switch .So it will not turn over long enough to pull fuel up to start with out a shot of ether and then it will start ok the rest of the day and will run great .<br />PS I found out with foot preasure on top of flywheel will keep the starter engaged ?? need help thanks bob

not too sure about starter, BUT Either IS BAD<br />on a two stroke motor, think about it there is no oil mixed in with either.<br />keep posting<br />Darian

Darien is correct. Starting fluid with ether and no oil is deadly on 2 stroke engines.<br /><br />Your problem could be in bad connections in the battery/starter cables. Remove, clean and reinstall all of them, with particular attention to the ground cable connection to the engine block.<br /><br />Good luck.

rthalls....two things....<br /><br />Make sure the flywheel is torqued down to specs and ....<br /><br />Make sure the "good" battery is indeed good.<br /><br />Your symptoms sounds more like a battery with low amps.

I think the Idle timing or lync and sync is off, causing the starter to kick out because the engine fires quickly and then dies off. In other words, it fires right away, but does not continue to run for some reason and the starter kicks out as it's supposed to. When you put your foot on the flywheel, you put some drag on the motor when it's cranking and it continues to crank with the load on it. Just a theory...

I know ether isn't good but squirting a little gas and oil mix dosen't start it [ don't have a manual for motor ] all battery conection have been cleaned and checked. Rick how do I check the idle timeing . thanks guys bob

Re: 1991 evinrude 25 HP electric start -starter won't stay engaged

no the motor will not rope start for its unable to pull enough gas up , if I take the motor cover off and turn the choke to manual and pump the bulb tigh it will then start on the first comporession turn ..........
