The smallest nick on the side of the crankshaft is irreversible damage and will ruin any new seal in no time so methods 1 and 2 are VERY risky. Even in removing the rubber part of the seal with a knife (which helps but is not necessary) make sure your blade only runs agains the seal's metal inner edge and never touches the crankshaft itself. Finally, the OMC manual calls for smearing a thin layer of gasket sealer around the seal's outer edge before pushing it back in place. Salut, mon ami !
Great video, test & explanation ! That tool from Richards outboards is the way to go. Less chance of damaging the crankshaft surface than with methods 1 & 2. Thanks for sharing your time, knowledge, expertise & the tool source.
I used a Center Punch to knock a few holes in the oil seal, then I used your Screw trick to drill and push the seal up and out with the screw. Worked like a charm on my 1957 35hp Lark
If that seal removing tool is a standard size black pipe you could buy a pipe nipple and pipe cap to fit, drill and tap a hole thru the center of the cap, stick a bolt in it and use a pipe wrench to thread into the seal. Basically the same tool for about $5 and no welding required.
Very good. I learned something valuable. I've got a 57 Evinrude 7.5 hp that is a bit hard to start. I'll do this check on it. Probably going to buy the tool.
Love your videos. Saving me a bunch. My upper seal is leaking a bit and I’m betting my lower is also. I have a 1961 40hp Johnson. I can’t find a video on the lower anywhere. Is it a monumental task?
Hello mr Tmike,great video by the way,it’s Ben a while hope all is good,would appreciate if u can make a video of replacing the rubber motor mounts that sits on the sides of the motor,I have a 1956 7.5 evinrude fleetwind,and one of the nuts and bolts are snapped off,it would be appreciated when u get a chance for a new video if u would consider making one on this motor.
Thank you for this great video! I am presently restoring a 1965 Evinrude 3hp with a bad upper seal. Does anybody know the part number for this? I cannot find it anywhere 🙂
Is there any tricks to remove a very stubborn flywheel on 40 hp evinrude te40ele1a ? Have the 3 bolt puller on it and have tapped as hard as I dare with no results.
Well, smaller motors don’t have seals they have oil slingers. Larger motors have seals and I’ve tried to build plates to seal off powerhead but decided this way is better and easier. Gave up on pressurizing powerheads.
The simplest test for that crank seal I've seen, perfect!

Thanks Mike, my mq-10r is coming along fine with your videos
Great video! Appreciate the way you share info!
Great job mike thanks again for your info it helps me a lot 👍
Thanks Mike! Testing tomorrow but oil is everywhere under the flywheel so pretty sure it needs one. 65' Fastwin. Good stuff!
Great video! Very informative! Keep up the good work! Looking forward to next vid!!

It’s easy after you get into it. All my videos should apply. Parts are just bigger. Good luck.
is the part number for 1958 18hp Evinrude upper crank case seal The same 18-2018 I had oil all over my magneto plate thank you very much
Could you use a tool like that for prop shaft seals?!

Love the videos
I got a 53 johnson 25hp seahorse, what are the starting carb adjustments
Fantastic. Thank you
Enjoyed , Great video
I have a 5.5 5402b mine looks a little different a few more parts?
Is the upper & lower seal the same part number? I need to change my lower seal but am only seeing diagrams showing upper only. Thanks.
I think so.
Hi, would a blown crank seal prevent the motor from starting? My motor has good spark, but won't start. thanks
Normally not - would run rough at high speeds
'57 Evinrude Fisherman model 5514, looks different. Any ideas?
Will that seal puller work on a 1984 mercury 35 hp. Steve in youngsville, LA
Don’t think so
Thank you for this great video! I am presently restoring a 1965 Evinrude 3hp with a bad upper seal. Does anybody know the part number for this? I cannot find it anywhere 🙂
I have a 74 25hp Johnson and i want to know if you drive the seal all the way down tight. Or flush with the outer ring?
Flush
Is there any tricks to remove a very stubborn flywheel on 40 hp evinrude te40ele1a ? Have the 3 bolt puller on it and have tapped as hard as I dare with no results.
Leave the puller on it and pour transmission fluid around crank shaft. Tighten and spray every day for a week.
thanks. Have it sitting with pb blaster 2 day now, Will keep trying.@@michaeljsimon
TMike- what was your conclusion on pressurizing the crankcase to test for leaks?
Well, smaller motors don’t have seals they have oil slingers. Larger motors have seals and I’ve tried to build plates to seal off powerhead but decided this way is better and easier. Gave up on pressurizing powerheads.
Great !!
$50 buck is cheap in my opinion if you do this job very often
