70 HP JOHNSON 1987 - Link and Sync - She Runs !

[@Pop_Hockenbush]

I have the exact same problem with my Evinrude 70 . Adjusted the carbs .2.75 turns and it seems better .

[@THISOLDOUTBOARD1]

Thanks again !

[@craigfievet788]

hi rebuilt the carbs on 89 70 hp evinrude fixed low idle problem but lost top end what did i do wrong thanks for sharing videos

[@THISOLDOUTBOARD1]

Hey. I don't know I wasn't there! Haha Just kidding! I hate when that happens. Might be in the linkage adjustments. If you adjusted the linkage at idle you'll have to also adjust it at wot. I'm thinking the butterflies may be opening too far. Did you sync the carbs at idle? The motor should idle by itself, without the roller touching the throttle cam. The mark on the cam will then line up with the roller barely touching it. Then put the throttle all the way to wide open and check the "roll pins" on the butterfly shafts, they should all be in a perfectly vertical position and must match, if they don't match then you'll have to resync the carbs. At vertical position means the butterflies are at a perfectly horizontal position, if they go over that position the motor won't run right at full throttle. Here's a link to a video that should help. Curious to know what you find out. Thanks for tuning in. kzbin.info/www/bejne/q3u3qWCvnLplabc

I have a 1986 110 Johnson she will fire right up and idle just fine but when I give it the throttle she dies any suggestions?

[@THISOLDOUTBOARD1]

Hey Sean. Thanks for tuning in. Unfortunately the list of possible reasons is too long. It's best to have an omc manual for trouble shooting all the possibilities. Hopefully its something simple and you can start with some basic stuff. Clean the carbs. Check for air leaks in the fuel system and around the intakes. Check for good strong spark on all cylinders. Check for good compression. And check the link and sync. I was dialing in the carbs on my 92 60hp 3 cylinder the other day. I was surprised that just one carb being a little off would kill the motor. I couldn't believe the other two couldn't keep it idling until the 3rd carb was dialed back in. So like I said, hopefully its something simple. Check ebay for a good cheap used omc manual specific to that model. Good luck, Thanks again & Stay tuned !

[@artbentley8594]

Hey, Good morning. I have a 1975 70 horse Johnson. Runs perfect. I put ear muffs on and start water. Start the motor but it doesn’t seem to pump much water out of the two upper exhaust holes. I read that it won’t until thermostat opens. Does that make sense?

[@THISOLDOUTBOARD1]

Hey. I'm thinking probably on a 75 you'll see more water when the thermo opens. Have you? The problem is usually the muffs, they just dont bring a lot of water like in a tank. Thats also why they say not to rev it up to much while on the muffs because of low water circulation can cause overheating. Thanks

[@artbentley8594]

Thanks again for your fast and courteous response. I haven’t let it run to long with fear of burning it up. How long do you think it would take for the thermostat to open. Thank you again

[@THISOLDOUTBOARD1]

@@artbentley8594 Hey. it shouldn't take to long. You can put your hand on the top of the motor over the cylinders. You should be able to tell if its to hot as to how long you can hold your hand on it. Hahaha I know it sounds funny and I cant tell you how long you can touch it for, I guess it just comes with experience. Go to boatinfo.no and check the manual. I dont know any history on the motor. Did you just get it? Does it even have a thermostat in it? Have you run it on a boat? You say it runs perfect, or do you mean it idles perfect? So if it were mine, I would want to know whats going on and I would run it, but keep an eye on it at the same time, but thats just me! Curious to know what you find out. Thanks again & Stay tuned !

Hey Jack. Alright you asked for it! Hahaha, fuel tank vent or hose restricted, restricted fuel supply system, restricted fuel pickup, faulty anti-siphon valve, clogged fuel filter, fuel system air leak, fuel or oil inlets fittings plugged, air leak on fuel supply side, restricted vro fuel supply system, plugged pulse limiter fitting vro, damaged vro unit, throttle cam pickup misadjusted in linkage, idle speed to slow, restricted fuel distribution manifold in carburetor, carburetor base gasket leaking, plugged high speed orifice, plugged high speed nozzle vent, plugged float chamber vent, incorrect orifice size, warped intake manifold, manifold gasket leaking, leaf plate gasket leaking, leaf plate bent chipped or broken, leaf plate assembly screws loose.

Please Help. I have an 1989 Johnson 70HP rebuild by Coastline Marine in Florida. The rebuild cost $3180. (rebuild include: bore the 2 bottom cylinders to the next larger size piston. replace the top piston for cylinder 1, rebuild carbs, new thermostat). The guy told me to check the ignition and timing by a mechanic. I have called every marina in Boston area to have them check the timing for me but no one is willing to work on older motor so I have to check the ignition/timing myself. I have watched KZbin videos bought 2 manuals to do the timing/ignition myself. When I check the TDC of the motor, new TDC mark that I've found is 2.5" to the left of the factory TDC. Is this correct ? TDC needs to be correct before I can continue forward. Thanks for your help.

[@THISOLDOUTBOARD1]

Hey. Thanks for tuning in. Did you get an OMC manual specific to your year/model? Anyway. Here's a video that shows the correct procedures for your motor, with throttle cam part number 0431707. If it doesn't come out right, I would pull the flywheel and check the flywheel key. If you need an omc manual try ebay for a good used one. And if your worried about the high speed timing being off you can always do the Joe Reeves WOT timing method. I did a video using his method or just google it for the procedures. Thanks again ! kzbin.info/www/bejne/q3u3qWCvnLplabc

[@vinhoi69]

@@THISOLDOUTBOARD1 thanks. I have watched that video multiple times. But my problem is that the TDC mark that I have determined is no where near the fatory TDC mark. Is it possible the fly was installed incorrectly during the rebuild or the fly wheel can only goes on one way?

[@ct1762]

@@vinhoi69 this is old i know, but what is the motor doing/not doing that you think you need to check the timing? timing on these is simply idle speed in forward to exactly 800rpm. take cam roller and adjust throttle cam so they just barely touch, and back off idle stop screw 1/2 turn. it will now be at 750rpm. i'm not sure why you are so obsessed with pickup timing. if you want, set the timing point with a piston stop tool to get the correct reading, then do joe reeves high speed method to make sure its under 18 degrees. really simple stuff here for me.

Hey question for anyone who sees this have a 70 hp johnson starts and idles great put it in gear and dies played with throttle and made it idle higher did not die when put into gear but makes a clunk ( assuming from the high rpm idle now) got boat moving but now full throttle now seams like half throttle and can get boat to plane now any ideas?

[@THISOLDOUTBOARD1]

Hey. could be as simply as an air leak or more involved like not firing on all cylinders. it's going to be a process of elimination. start at the fuel tank and work your way back. air leak in fuel hose. tank vent open. fuel pump pumping. carbs cleaned/rebuilt. floats adjusted. check compression . check for spark to all cylinders . new spark plugs. good coils. link and sync. basically give it a major tune up. take your time and dont assume anything. you can find a manual here. boatinfo.no/

Been working on I 75 horse Evinrude it runs for five minutes shuts down run for another five minutes Shut down do I have a heating issue thermostat switch heat switch or water pump issue please send reply

[@THISOLDOUTBOARD1]

Hey. Its hard to say with that description as to whats going on, Is it pumping water? does it feel hot? What may seem like a overheating issue could be a fuel or ignition problem. And vice versa. You'll have to get back to basics. Its a process of elimination with these things. You have to eliminate/rule out one system at a time. Go through your entire cooling system until your convinced its working properly and all parts are good with no issues. If you still have a problem then move on to your fuel or ignition system and do the same. You could have a bad fuel pump or a coil breaking down. There's rarely one answer to any issue theses things have, and never assume anything! Just because it looks good, or clean dosent mean a thing. After doing so you will know that motor like the back of your hand. How it ticks and what makes it tick. Any future issues you'll know right where to go and how to deal with it.You have become one with your motor. Hahaha getting a little dramatic but its all true. Every bit of it. You can find a free service manual at boatinfo.no. Take your time. You'll figure it out. Thanks for watching and commenting. Stay tuned !

if there is gas spitting out of a carb when it spits the motor will usually misfire-its called a lean misfire-adjust the idle screw out to richen upthe mixture-if no improvement den clean carb est idle jet and screw and idle circuit-sometimes have to soak carb in carb cleaner to get it clean-the isfire is called a lean misfire and if not remedied will ruin a motor-

[@THISOLDOUTBOARD1]

Hey. Thanks for tuning in! These carbs have a fixed jet, orifice or air bleed. There is no idle/slow speed adjusting screw/needle. The spitting, if I remember correctly was from bad reed valves and I ended up swapping them out. But I know what you mean about a lean condition, or lean sneeze. I hate those carbs you can't adjust. Same thing on the 55 hp Evinrude I had. Never could get that thing to idle right. Thanks again & Stay tuned !

Hi, these videos are of great help to me. My Johnson 1984 70 HP (very similar to this one) seems to have the same the same issue. I would like to exclude the prop being the problem. Do you have the dimensions of the changed prop that solved your problem? Thanks in advance! Greetings from the Netherlands!

[@THISOLDOUTBOARD1]

Hey. Thanks for tuning in. No I don't have the prop sizes. Have you tried every other option to get your motor running right? This thing was a Beast. It was so fast it scared me. Then the owner blew it up. Bad gearcase. Overheated. Never was the same. I tried everything. Then we put the original prop back on and she ran again. But still wasn't the same. I'm just saying a prop swap doesn't always work. I would check what prop size is standard for your model and start there. What size is on it? Thanks again & Stay tuned !

[@laurencevdvalk]

@@THISOLDOUTBOARD1 Hi thanks for your swift response! Ah too bad. No I am in the process of troubleshooting. On high RPM it runs like a beast. At idle however, it runs rough/stalls on low rpm and when you put in gear it stalls. It sounds like a fuel issue. I just cleaned the carbs and will replace the fuel lines. I am not sure what the current prop size is, I will measure it tomorrow. Thing is, I see several sizes for this model (J70TLCTE). Sorry to hear the engined overheated, these are great engines.

You have the primer bulb on the fuel-line on backwards. The arrow on squeeze-bulb is supposed to be pointing towards the motor, not the fuel-tank.

[@THISOLDOUTBOARD1]

Hahaha Hey. You had me worried there for a minute. But I would believe it on this thing if I didn't know better. It just looks like its pointing in the wrong direction. Camera angle creating an illusion. The Fuel line runs under the splash well and out through a hole in the back and runs up into the powerhead. At that angle it does appear to be the wrong way. Good eye! Thanks for watching and commenting !
