    Ignition stator repeat failure

    Question I have a mercury 25hp outboard engine that I installed a used flywheel due to ringear teeth failure. The flywheel I purchased had 4 magnets and my old flywheel has only 2. The marina I purchased flywheel from said that didnet make any difference. But had 2 stators installed since...

    Starter Bendix bounces up& down while cranking.

    Thanks just doesn't sound like any other motor I have worked on in past, that's all.

    Starter Bendix bounces up& down while cranking.

    Thanks for the reply and info. I also have had motors since the 60s. Never thought about hooking the negative on bolt meter to actual starter. Have had it on the block and the battery when I did all the above test. The other thing about this starter is I feel there is too much play between...

    Starter Bendix bounces up& down while cranking.

    Have a 1996 mercury Tracker that while cranking Bendix bounces up and down. Won't stay fully engaged. 96, 25EL, 0G309267, 2 new starters, new solenoid, new battery, 12.4 battery volts, 10.5 cranking volts. Any ideas some say nature of the beast. Has full engagement of teeth.

    Flywheel magnets

    Curious why do new updated part number that superceded have more magnets than original flywheels? 25 hp Mercury 2 Stroke Sn# 0G6309267, 25EL yr. 1996. And if I install a 4 magnet on a motor that originally came with only 2 magnets, does it hurt anything.

    Flywhee noisy when cranking over.

    Starter is brand new OEM from mercury with a 1 yr warranty. My customer installed starter, solenoid, and new battery. Then they brought to me because of no start, found bad low side ign coil (open). Installed engine started up but when cranking it sounded terrible. I bench tested, and amp...

    Flywhee noisy when cranking over.

    Thanks, just never saw the top and bottom flat areas of the ringear worn like that. Teeth actually look pretty good, they don't look worn?

    Flywhee noisy when cranking over.

    96 25hp mercury Tracker, sn OG309267. Flywheel. Noisy not engaging like it should. Bendix gear seems to have too much play back and forth. Ringear feels like sharp edges too and bottom you can feel running your finger over them. Can't send post video???

    No spark

    Ok I know the (LS) low side coil is open circuit and it controls the idle to about 2000 rpm if I'm understanding the system. So if it's open I won't get any spark to either primary coil correct.

    No spark

    I guess I'm curious on how a trigger fires a scr when magnet is fully magnitised all the way around.

    No spark

    Sorry motor is a 96 mercury Mariner 25hp electric start. Sn 0G309267.

    No spark

    My question is this how does the trigger work for spark. I understand it has a center magnet separate from the cdi controller. But how can it reverse poles to collapse a capacitor if this center magnet is magnitised all the way around it. How does the trigger sense the change . I would have...

    Evinrude 9.9 elec starter lock out cam

    Have a 1998 Evinrude 9.9 electric start. Like most in this era it has a starter lock out that as long as you are in gear you can not use pull rope to start. There is a small cam system under recoil that when in gear will not allow recoil to engage. I have searched all over but no one has info on...
