your motor doesn't look bad at all to have been under. get some oil in those holes quickly. MMO would be best in the spray type if you can find it and spray down the cylinder walls and get the other head off and oil her as well. then open the carb butterflysand spray those fullof oil too.

i poured mmo in plug holes about two weeks ago. guess i should pull off other head and clean up all 6? you think the crank bearings will be allright? i dont wanna pull the motor apart that far. but, on the other hand, i only wanna fix it once. and what are those relays on top left of motor? are they for tilt/ trim?tx

most likely thay are ok but not sure, but you may need to pull it apart hone lightly and then just use new rings. But you will need to get those holes oiled asap to stop rust. and then try to get it to turn. may need to put a breaker bar on the flywheel nut and get the motor to turn over. I've beaten a Mercury's Crank with a hammer to get loose once, once it can loose the motor ran fine afterwards. goes to show you never know.

Once you've got all them oiled then take the cover off the top of the flywheel and get a wrench on it and try to get it turning. Once it starts to turn work it back and forth and keep oiling till it finally turns all the way around. Yeah those relays are for your Tilt /Trim

Good info. but hope I NEVER NEED IT!

hey skools, when i took cover off of flywheel i was expecting to find a large bolt like on my 79. not so, instead there is a little bitty bolt. and six more little one around the flywheel holding it on. i am afraid that if i torque on them they will break. what should i do?

yikes :o um well still will run shy a bolt. um can you turn it at all?

no, never got it to turn. nothing to grab on to. i broke the center bolt, tapped it out, broke another one! tried vice grips on top of crank, removed flywheel first, but it just kept slipping. thinking i might stop by welding shop tomorow and get them to weld a piece of pipe to the flywheel so i will have something to turn. cant think of anything else.

don't mess up the fly wheel or crank, i'll get you some pic of my homemade flywheel rig for holding while removing the center nut.

that would be great. at this point i am on a mission. this motor will turn! iworked on it all day today, stayed home from work, and am to the point where i am willing to trash this flywheel and buy another. hell, i even considered dynamite during the hottest part of the day!

i hate to ask this but do you have any pistons about half way in the middle of it's stroke? if so CAREFULLY take a piece of wood and put it on the piston and hit with a hammer some to see if the motor will turn. if you have more than one in the midle of a stroke rotate around the motor tapping them to try and get her loose. don't go wild knocking holes in the piston. post a pic of your flywheel so i can see if my rig type would work too. Your top hole in the pics is on the botton don't beat it, the other 2 look like ones to use but look at the other side too.

i drilled and tapped a couple of holes in the flywheel, then bolted a piece of flat bar to it so i could try and turn the motor. yanked on it for about 5 or 10 seconds and she broke free! prob so ez cause it has been soakin in mmo for a month. worked till it turned free all the way around. it was pushin some nasty lookin brown fluid out so i just kept sprayin MMO in the carbs and turnin till it was just clean MMO coming out. she turn free and smooth now! one thing, when the bottom starboard piston goes back in, when it passes the port hole in the wall it makes a sucking sound. i dont know if this is good, bad, insignificant. at any rate, what ya think skoolz? carbs next? should i get some 400 grit and soapy water, roll the pistons all the way in and 'hone' the cylinders? no race tomorow so i should have a little time to play. tx

mommy thinks you should worry less about the boats and jeeps and concentrate a little more on the yard and painting the house!
http://i58.photobucket.com/albums/g263/urbaneve71/baby/Picture019.jpg
but, i think you should take apart the starter, clean it out real good with some water, put it back together and spin the motor over and make sure you get all that nasty crap outta there. speakin of nasty crap, i better go find mommy cause thats HER job!

the sucking is good sound. means the piston is sealing andthe reeds are too. can't hone with the pistons in her you'd never get all the crap out of the cylinders. just keep the cylinders oiled and put a good starter on her and spin it alot without the heads on it and keep spraying oil on the cylinders while it spins over.

took the starter off and took it apart. didnt look bad but i hit it wiyh the water hose anyway and let it dry. was on front porch putting it back together when some dude lost his trailer right in front of my house. i dropped everything and went to street to see if anyone was hurt. came back and one of those little springs is gone. apparently never to be seen again. any idea where to find one?

It probably bounced about 20' from where your at.

nope, i found it. i figured it fell between the deck boards so i removed a few of them and hunted for what felt like an eternity. after i gave up and reassembled my porch i found it cleverly hiding inside the starter. so i put it back together and reinstalled it. did what schools said and turned her over while oiling her down. still got a little rough spot on the bottom starboard cylinder. by rough i mean not extremely smooth. when i run my finger over it it feels like 1400 grit sandpaper. i hope this will be acceptable cause to hone it will require removal of the powerhead to get to it.
talk to me skoolz. whats next?

put new head gaskets and the heads back on and test your compression. then post the readings. if good i'll say crack her up and see what happens.

07-30-2006, 07:22 PM
what about the carbs? i will prob have to rebuild them, huh? or should i do that after compression test? tx

after the test.

k, i got the heads back on. this thing doesnt have head gaskets. just o-rings. at any rate, i bought a cheapo compression guage at auto zone. hooked a fresh battery up to the starter and went at it. for some reason the motor turned over real slow and i was only getting 30 to 40 pounds per cyl. just to see what would happen, i pulled one plug from the other side and tried again. motor turned much faster, still pretty slow though, and reading jumped to 75 pounds. then it started to rain so i gathered my tools and came in. anyway, i gotta ask, how do you test compression on an outboard? should i pull all the plugs?
Skools Out
08-01-2006, 02:16 AM
pull all the plugs out and test the motor turning it over till the gauge raise's no more.

not lookin good for team no-bucks. port side, top to bottom, 90-115-90. starboard side, top to bottom. 120-120-110. seems wierd cause i ran the test three timesand those two 90's cameup from 75. wondering if i didnt turn over the motor enough with the heads off. probably just wishfull thinkin. watcha think skoolz?tx

When testing give it full throttle, open the carbs up. I'm assuming it has carbs! Billy Mac ;D

if it had rust in the cylinders it will take time to get it's compression back. Treat it as a new motor run it on premix with double oil in the mix. Run it on a hose till it gets warm at idle and middle rpm's like idle up to 2000 to 2200 for a couple min then back to idle. Once warm. Turn off let cool. test compression. the run again same way till it gets warm then test compression warm tell us you results then. Sounds fine to me for a submerged motor.
racerx
08-01-2006, 04:49 PM
so what do i do next to get it running? clean carbs thoroughly or complete rebuild? i also need a new ignition switch, i dont have a key for this motor. do you think it would be a good idea to replace all the fuel lines. also, how do i disengage the auto mix? tx
Skools Out
08-02-2006, 01:09 AM
just run the auto oiler too with the premix that will make your motor double oiled, and just clean the carbs good first so you will know it runs first. If you need a key check the switch number and call a Johnson dealer tell them and they will have you a key in stock.
racerx
08-02-2006, 01:17 AM
yea, bud. saw ur post about the key on another thread. will pick it up tomorow. pulled all the fuel lines and washed them with the hose, let them dry, then shot some mmo thrue them(on gallon #3 now,lol). will clean carbs and reassemble tomorow. got my fingers crossed. little worried about the crank. i guess i will know pretty quick when i get her fired up!tx

ok skoolz, the dude at the omc dealership got me pretty nervous about my bearings. he says i got about a ten percent chance of this thing workin out. he says that if i get it running it may flat spot the bearings and just when i think everything is fine they will break loose and start banging on the crank and blow my motor! after he gave up on trying to sell me a new e-tech, he tried to sell me bearings and stuff to replace at about 1400 bucks. on the other hand my buddy chris who is a damn good boat mechanic (he had a major stroke few months ago and i dont feel right askin him for help) says i should fog it and no worries.prob is he only has half a brain left. anyway he said he wants to come over and supervise from his wheelchair and help me get it running. it will make him feel better since he cant do much anymore. plus he insist on paying me back for the wheelchair i built at his house.
now its complicated. if we pull it off it will increase his sense of self worth and thats great. but if it dont work i worry how he will feel! he says he will supervise me through replacing bearings if i want. but i dont realy wanna. not sure the motor is worth the time and money. i wanna kick the pig all day long! watcha think bud?

bearings show be ok crank it see if it rattles or anything, let it run easy for a little bit in the yard you should be ok don't worry.
