15 hp 1976 Evinrude flywheel hard to turn

[supercoolbabe]

My motor sticks in one spot when I turn the flywheel. I just cleaned dirt out of flexplate and put back together. I did not move anything so I could not mess up settings.

Have you tried pulling the plugs and attempt to rotate the flywheel? Compression in the motor could make the flywheel difficult to rotate.

Is the motor new to you and is it electric start.
When you turn the flywheel does the stator plate want to move with it?
Did this just happen when you cleaned the flywheel or was it there before?
If the stator does not look like it is hanging up on the flywheel pull the lower unit off and see if it gets better.

^^If removed or loosened stator or drive coil screws, either could be rubbing slightly against a flywheel magnet -- not lined up perfectly on their mounting bosses.

It is a rope start motor. Yes it ran great (A little hard to start sometimes).. Same thing happens when plugs are removed. How do I tell if stator plate is moving with flywheel? The motor has not run since it was submerged. I have done all the things suggested to get motor running. Just missed the the plates under the timing plate. Everything felt tight when I reinstalled the timing plate. Did Did not remove coil. When I remove lower unit is there a trick to get shaft, water tube, and gears lined up so it will go back together? I have been unable to get the lower unit on my 6hp reinstalled. I have the service manual and Leeroys ramblings as guides.
I will remove flywheel again to be sure there is nothing rubbing. Thank you

Being submerged was a VERY important piece of information that we needed.
How long was it submerged?
How long was it out of the water before being started?
Was it running when it went under.
They really need to be started as soon as possible to prevent damage. If it was more than 24 HRS you will probably need to tear it down to make sure the bearings are ok.

First of all,someone elses post is in mine. It was not running when it went down. It was in fresh canal water for about 10 hours. It has been about 2 1/2 week without running. I know it is important to get it running asap. I put wd40 in the block, then oil. Drained no water. Removed carb and cleaned it including jets and removed all water. I have been trying to start it with starting fluid, fuel with oil in block and carb. The spring in the pull cord broke and I had to fix it. One of the spark plug terminals broke and I replaced it. I cleaned gapped the points. I used a multimeter to check coils, etc. I replaced lower gear lube. It doesn't even try to start. Is it totally ruined? I worked on it everyday for 4-6 hours since in went down. IS it ruined? I have spent so much time and money on it I hate to give up. It took $200 to get fuel problems fixed and it ran for 1 1/2 years. I cannot afford $85 to take to shop just to have high voltage checked. I thought I had found the problem when I removed points plate and found muck in it and cleaned it. Now flywheel has a bad place in it. I have been working on motors(seahorse) since I was a kid. I call it "hatefull" because it is so mean. I am the idiot who sunk it but it is the first time in 50 years I have done something so stupid.

What bearings are you talking about?

 

[scout-j-m]

He probably means the needle bearings in the crankcase. Those are the tiny rollers which separate the connecting rod face from the crankshaft journals. There is also a main upper bearing which may have issues.

 

[flyingscott]

Those are exactly what I mean because of the way they run they are perfectly clean and polished so if they get water on them they rust VERY quickly. Try new points and condensors and have you pulled the lower unit off yet

I am giving up one that motor. I am tired of working on it and not getting any results. I have a 1980 that I was told was a 1975 that I used for parts. I think it is a better motor (electronic ignition). It is just missing a carburetor and propeller. I assume the prop from the 1976 will work.

 

[jimmbo]

a lot of people prefer the point magneto ignition of the first generation of the 9.9/15 series. Very reliable and easy to service. Have you tried disconnecting the stop button? It may still be shorting out

 

[supercoolbabe]

Yes. No problem there.

 

[supercoolbabe]

It is not easy to service to me. It has been a pain to work on. Have spent more time working on it than boating.

Plus it has been 2 weeks since it went underwater and still will not start. I do not want to take the time to rebuild the whole thing.
