Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

well the starter lead tests 12.5 volts when not connected to the starter and it tests 5 volts when connected to the starter. this is after installing a new solenoid from the auto parts store. the ford solenoid seems built a lot better than the original. I also cleaned around the mounting bolts on the starter so they were bare metal just to make sure.

I still am not positive of what made the short in the first place. could the starter have caused this?

I will try the jumper test just for the heck of it then post before i get my starter rebuilt:/

jumper test completed, it still turns slowly. wow it did make one hell of a spark show. looked like i was welding. I am gonna get the starter rebuilt. but i still dont know where the short came from. either way i have learned a lot from you guys- thanks, i will post my final results when i get the starter back.

..and how hard is it to rope start a 75hp with good compression? lol....

I'd bet you have a cracked field magnet in the starter.

well i got the rebuilt starter back, i was told that it needed new brushes and a good cleaning, i tried it in the garage not starting but just turning it over. it seemed fine. i took it to the lake. when i tried to start it. it fired right up ran for a few seconds and locked up. while running it made a clanking rapping noise. it sounded terrible. upon inspection i found that the starter gear did correctly disengage. the flywheel was so tight that i could not turn it by hand. later i turned it in the garage with a breaker bar it poped loose after about an eigth of a turn. it also seems to start slow due to the tightness. could anything have been damaged while the starter engaged in gear? any ideas? if not this engine is going to be scrapped for parts bc i have had it.

Bad, Bad, Bad. Something is terribly wrong in the powerhead. You've been focusing on the wrong thing. The starter is not the problem. Don't attempt to run that motor any more till you find out what's wrong with it, not that it makes much difference at this point. It might be a candidate for the bone pile.

At a minimum, remove the cylinder head in order to inspect the pistons and cylinder walls. Even if you have no mechanical expertise at all, at this point you have nothing to lose. Just be sure to disconnect the battery first.

Let us know what you find.

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

i will pull the head tonight and see what is going on. i can pretty much put togther any engine two four stroke but i have never attempted the internals of a outboard. from what i gather parts are more expensive. just out of curiosity why would internal problems cause the starter bendex to engage?

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

How is your memory? The first time the motor made a racket and quit and you pulled the cover off and discovered the starter engaged, did you attempt to restart the motor before you removed the cover? That would be the normal response for anyone to take. That attempted restart would be how the bendix got engaged. It didn't disengage because the motor didn't restart to kick it back down.

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

that makes perfect sence. i cant really remember but that is probable. very good logic-thanks

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

well i pulled the power head and the middle cylinder has faint scratches in it and some micro-scopic shinny flakes of metal but hardly noticable to the eye. i will post some pics later but it definately looks rebuildable. but is it worth it? i will do the work myself so i guess i need to price parts.

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

Depends. If the crankshaft is bad (trashed rod bearing) it gets real expensive real fast.

ddcarter just rebuilt his 3 cyl. post to him and find out what it cost.But one big thing to consider.How is the rest of the engine look.If you only run on lakes,you might be in good shape.Does the engine have trim and tilt,is that in good order,hows the lower unit,much corrosion.Is the wiring clean,or filled with splices and butt connectors.etc. as mentioned,if the block has any major cracking ,you could be getting over your head. At the very least,I would think you SHOULD bore all cylinders to next oversize,new pistions.bearings,all new gaskets,again ddcarter could help you on price.If the crankshaft suffered damage its another few hundred for a used one.let us know what you find,the head is a good place to start,but I believe you mightas well keep going if your up for it

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

freshwater only, no trim- manual tilt, new prop, wireing looks great, lowerunit has recently been serviced, paint looks good- crankshaft is debateable- lol how much can i make on parts if i took it apart? whats a lower unit worth?

 

[mikesea]

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

if your looking to part it out,check on ebay,about the only thing worth anything would be the lower unit,i would guess 4to 6 hundred,if its real clean,and someone needs one,i dont know what yrs. the one you got would fit,thats important,if it only fits the 70's and not the 90's ,there might not be many buyers out there. as for the midsection,without trim and tilt,its not a very wanted item.if the block and crank are good you might make a few bucks there. but i doubt they are saleable..you might be able to find a decent used 3 cyl.omc for a good price,then you would have extra parts,andcould use all your controls,just a thought

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

thats what i was thinking. i only paid a grand for the engine so i might just part it out. i also have a mid seventies 20ft starcraft with a chevy 4 cylinder mercruizer. the hull is aluminum. the motor has less than 300 hours on it. it just needs a coupler and a set of controls replaced which i allready have. i also have a 83 johnson 150 that i am gonna rebuild or part out. might just use the extra cash on the starcraft fix for a trolling rig. i will post up if i rebuild the 75. again thanks for all the help guys!

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

Regarding the 150,I am presently looking for a 150 johnson or evinrude to put my powerhead on.I think your i Pa.My 150 is an 84 that has been beat up by salt water,is yours fresh water and do you wantto sell it,as is.let me know

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

i disassembled the powerhead and here is what i found. as stated above light scratches on the cylinder and piston. then i noticed the clamp on the connecting rod was loose on both sides. there was even a gap there. upon further investigation both bearings on the conneting rod ends are shot. the one on the crank is in pieces. and the needle bearings on the wrist pin seem loose. but on the bright side the crank seems good as with everything else. so i am going to do a rebuild for the hell of it. is there any online site where i can get the torque specifications for the bolts inside and on the powerhead?

hey Mikesea check your messages about the 150

Re: starter gear stuck on flywheel-1975 johnson stinger 75hp

Adam,I received your message via my email too,did,reply,get it? about your 75,before you use the crank,be sure to have it miked up to be sure it's round,the metal in the crank is tough,but if that crank aint round ,your in for some trouble. The connecting rods too,I would bet if the block is good rods ,crank,you could rebuild it for under 800,You should bore the cyl. next size,this way you have nice new all round cyl,of same size,I like the wiesco pistons,I'm guessing they are about $120 a piece now(havent done any in 8 yrs) a gasket kit,probably could reuse the top and center berings,change the bottom,they are pretty cheap,new rod bolts,machining the 3 cyl.200-250 bucks.If you take the block to a machine shop that does outboard work,they might check your crank and rods for you,the shop I worked at ,would do it,takes 10 min.I wish there was a way I could get the 150, but shipping these days would break the bank.
