Minty 1974 Johnson 70 HP Doesn't Run Once in the Water

[@nigelbeaumont1109]

Regarding the KZbin comment you talked about. The Person that doesn’t know how to repair his Boat/Car or Lawnmower might just be a Doctor or Scientist or Airline Pilot… a person like ME who can repair almost anything that’s repairable could never ever become a Doctor or a Scientist or an Airline Pilot… that’s because I could not do the studying required to achieve these professions, this I know. I hope y’all are getting my point. Everyone has their “Niche”.❤️

Could be a stay at home mom, or a astronaut. Glad we have people like Brandon to document how to maintain things that are forgotten.

[@coastalcleaningandmaintena2884]

Nobody i know fixes boats on the water. Maybe 5% keep even tools in the boat. You keep your safety gear and required items. Even me ive had the same boat for 12 years since new and know everything about it. But if i have any issue i trailer it home anyway. Its also not environmentally friendly.

The unfortunate truth is that today you should specialize in something and not know how to do anything else, that is how you will make a big salary and pay everyone else to do things for you.

But I do for sure need his talents when my boat craps out! .... Let's face it. If everybody knew what everybody else knows, then we'd ALL be out of a job!

[@MarioBertolis]

Thank you for the time you spend to make these videos! I don’t have anyone in my area who will work on these older motors and after watching your videos I have had the confidence to tackle repairs on my 70’s Johnson.

[@newmoon54]

Brandon, Sonny here, I'm a 36 year J/Evin. tech in Wilmington, N.C. really enjoy your channel! You have the right blend of seriousness, humor, and humility (the latter is lacking badly in many outboard repair channels!)!! Keep up the good work!!! Some simple tips .. always assume fuel hoses are old, & replace them (90%+ outboards have 5-10 y.o. hose!)!! Of course if you know they're very new don't!! Lol! It's better to err on the side of preventing call backs, than to encourage them!!! Also, you may already know this one,, when replacing exhaust cover gaskets, wipe ~acetone~ well around the aluminum exhaust plate & cover after removing the old gaskets(s). Then after applying the gasket sealer to ALL ALUMINUM SURFACES allow the sealer to cure for 30 - 60 minutes before installing those parts!!! After bolting them in, re-tighten/torque them 3-x's!!! Allowing some time when you make the 3rd try!!! This way you're compensating for the squeezing out of the sealer, which cancels out your torque specs. Be on the lookout for early 90's 3 cylinder Mercury 90, 100 h.p. 2-stroke motors!!! Don't know if you've already experienced this,,,, but the factory messed up the tolerances between the cast iron cylinder sleeves, and the cast aluminum block(s), allowing the sleeves to get loosened when at temperature, and ~move~ backwards, towards the crankshaft,, and then the top piston ring releases itself because the sleeve moved back towards the crank!!! I guess you know the end result, lolol,, because Mercs don't have any cylinder heads, you'd have a mess!!!! Just thought I'd mention that one!!! Cheers to you~!~!~!~ Sonny.

[@ronmcwhirter3641]

Had a 70 once . Tha motor was indestrutable. 20 years zero problems. Of course it was winterized every year and well maintained . Very fast very dependable and always started in seconds. Traided it and the boat off on a 19 ft. Bayliner with v8 in-out. Love my boats. But its true. A hole in the warer you pour cash into. 76 now but my kids , my grand kids all benifited greatly. Miss those days.

[@PetersGarage101]

Finally someone has shown how to remove the carbs on these. I have this engine at home and I went on to a lot of sites and they said that a link sync had to be done after removal. I can see now that this is not the case. Thanks so much for going through this easy repair. I owe you a beer. All the way from Australia. Thanks Brandon.

[@Xpyburnt_ndz]

Totally agree with you! I've learned via your channel and others how to work on my 1989 Johnson 88 SPL and it runs like a top! I did have a local shop do my last water pump change just because it was over 10 yrs since it had been done. They were the ONLY shop that would touch my motor! So I'm now planning to do my own next time and thanks to you, I think I can tackle the job! Not bad for a 62 yr old geezer to still be learning! :)

[@bryanmele7961]

Your videos are great! They have helped me out tremendously! Thank You ! And, spot-on about Idiocracy, lol!

[@tandtadventures3645]

Great Video, Great you were able to figure out were the water was coming into the bottom piston, I had a similar problem with a 20hp merc, the bottom seal on the crank let go water came up into the crank, then it was left for years, when I got it it was locked up, took it apart, changed the seal and the bearing, ran great, yep lot of people operate things that they have no idea how to fix, that's were guys like you and I come in,

[@mikedurhan9941]

Love those 3-cylinder OMC loopers - especially those 1978 and newer with integral power TNT. Some of the best two-cycle outboards ever made........... Thanks for the video, Brandon.

[@newmoon54]

Yes, actually they're all a little over-powered! The #2 connecting rod(s) very often let go, and BANG out the side of the block!!! In 36 years I've seen so many of them through a rod. If you detune them they'll live longer!

[@randy1ization]

@@newmoon54 the real story is these motors were born as 75 hps.., they were detuned by making carbs with small throats and jets.. put a set of 75 hp carbs on a 65 or 70 hp and they run great and last a long time

[@alanaugust8853]

I once had a 1986 Lund “Mr. Pike” with a 70 hp Evinrude. The boat was awesome. But what I like the best on it was the engine. Nothing ran and sounded sweeter than that Evinrude! If I come across something like that, I will be very tempted to get back to that type of boating. It was so fun.

[@OGMoses_]

My grandad had a Johnson 65hp looked just like this brought back a lot of great memories of fishing and skiing. Great to see an old outboard still going

You do a great job, and I learned a lot from you. And you have inspired me to work on my own boat.

[@ronfisher2016]

Dam! That is a really sweet old boat an engine.

[@privateer0561]

You make it look much easier than it actually is. There are many roadblocks to repairing these old guys. For instance, I have a 1959 Johnson 35 horsepower, and while it is a very simple machine, it can still confound me. For instance, I went to replace the points, and despite doing it several times before could get no sparks out of it. I have the timing fixture that uses the marks on the Armature plate and use a meter to determine when the Points Break. It's a beautiful system, but for some reason I could not get it to work this time. I finally figured out that the points I purchased were from China and both were defective. That 70 horsepower Johnson is just beautiful. Advice for men and women who wish to repair these and keep them? Without question. Join your local chapter of the antique outboard motor club and get to know the old-timers. They are an invaluable library of information.

[@BrandonsGarage]

Those china points, jeez, what a problem. I'm sure many people out there are throwing out the engine because they can't figure out the new points are the problem. I don't think there is a local chapter. If there were, it would probably just be me.

[@paulmoir4452]

I own a few 2 cyls with that mageto and fixed a lot more, but I have never bought a new set of points. Coils I can't count how many! And the 18-5181 are great. But I've always just cleaned up the old points and tested and reused the condensors.

[@Larry-wl8ni]

Thank you for all your videos ive watched most of them 10 times may be more lol but everything has been very helpful keep them coming ..

[@mr.frowbrow8759]

super clean for the year

[@retro_grade]

I used to think these motors were boring (I'm more into 1950's outboards), but have started to gain an appreciation for them. Your is super clean as well (I'm so used to seeing ratty ones purchased on the cheap at the boat ramp that crank and crank and won't start). Sounds great as well. This video makes me want to keep the 1974 twin Johnson 50 HP Loop Charged outboards on my great grandfather's 1960 Alumacraft Queen Merrie, that was recently brought home from my family's cabin. I had always planned on switching them back to the twin 1957 Johnson 35 HP (red and white) outboards it was built with. Maybe I'll leep the 50's on it for awhile now. They're growing on me :)

[@danielrobert7181]

Hard to say why most people won'r even consider trying to fix things. I think it's a multi-factored issue. At the top of my list is the need to spend considerable time in acquiring basic knoeledge and skills needed to ensure outboard aintenance while these days, time is the least available commodity. Regular maintenance of 2-stroke motors including carb cleaning is definately within the technical reach of most owners but then, getting one's hands grease dirty is not very valued activity anymore. Thanks for your great videos !

[@astrawally8448]

Nice video. I'm currently resurrecting a 78 johnson stinger 75. Seized steering, trim motor wouldn't go, about a meter of control cable missing (can you believe that someone saw fit to remove a part of an 8 wire cable?), no key, no battery terminals, but good compression and looks fairly well kept under the cowl that is. I've got her running and steering now, but the carbies will need cleaning. She is an ol girl worth saving. Labour of love, as are most boats.

[@judgedayan9934]

I had the same problem with a 1972 Evinrude Triumph 65hp 2 stroke. The problem was some debris floating in the water floated into the prop and up the exhaust pipe. When the engine was out of the water it ran fine, but in the water the debris rose up the exhaust column and occluded the exhaust port causing the engine not to run. when pulled out of the water, the debris dropped down allowing the engine to run.

[@flycatchful]

Who would have thought that was the problem.

For whom it may be worth, I dont know if they had overheating resistor on these in 79, but I had an 82 Johnson that after hunting down a culprit keeping it from running more than 15 minutes (idle great), one last thing, I snipped the wires to the thermo switch. Never had a probelm after that. I checked the resistor by Ohms showed good, but wasnt after engine heated up.

You are right. Some people are time poor and don't have any interest in doing their own repairs. Ive always owned older model boats cars etc so I have to get my head around fixing them.
