35 horse johnson 1980

[diggerdan17]

just bought this motor and was told it ran fine last year....(ya i know ,famous last words)anyway the electric start is not turning the motor over very fast and then finally after hearing a bit of a fizzle the key will not turn the motor over at all.aside from fixing the electrical start, i would like to be able to get her running with the pull cord around the flywheel first.my question is this....do i have to do something like bypass a kill switch so that it will get spark when i pull the cord.i have only had experience with a 9.9 and 15 johnson and they had the tiller throttle if you moved the tiller control to start and pulled the cord it was good to go....do i just move the throttle by the steering wheel to half way and start cranking?

Re: 35 horse johnson 1980

For manual start, all controls should be set the same as elect. starting - throttle in normal start position, shift in neutral, ign. key in run position, choke/prime as necessary, etc. If you have a kill switch with a lanyard, make sure it's in place to run.<br /><br />The fizzle you heard is probably a bad connections. Remove (not just inspect) and clean all battery connections from the battery, all the way through to the starter motor. Don't ignore the ground cable from the battery.<br /><br />For elec. start, you need a well charged battery rather than a border-line one.

okay ..i will re and re the electrical ...on a side note i tryed and tryed to start it manually with the pull cord and after many many pulls i discovered i am not getting any spark at all when i pull the plugs and ground them to a bolt on the motor....any idea what the next step in determining what may be the problem besides going and blindly buying parts.

Re: 35 horse johnson 1980

Somewhere on the engine, there should be a large, rubber connector(probably red) that connects the engine wiring to the wiring going to the helm. The wiring going to the helm is not necessary for the starting/running of the engine. Separate that connector, manually crank it, and see if you get any spark at the plugs. If not, you have ignition problems, probably power-pack. If you do get spark, there is a wiring problem going to the helm. Check for spark at both plug wires.

Re: 35 horse johnson 1980

okay....update.<br />i,ve gone out and turned the key on, and pulled the manual pull cord on the fly wheel with one plug out grounded to the motor ....i have a decent blue spark that jumps a fair bit from both plugs.for now i will asume that i have adequate spark.next step will be to see if the fuel delivery system is working properly.i will order a carb kit and also go out and buy a compression tester just to make sure the engine is worth spending any more time on.the fuel tank and hose and fuel all check out a-1 as i had them on my 15 rude earlier today and she was purring like a kitten....anything else i should check?<br /><br /><br />oh ya, screen for the fuel filter was very clean as well.

save your arm. connect you battery cables, take a jumper cable from positive battery terminal, and touch to big connection or the starter. this will tell you if the starter is good. if it turn the motor over well move back the 2 large post on the starter solenoid, jump from one big post to the other, it should turn over, then jump the 2 small terminals if it does not turn over you probably have a bad solenoid. be careful it just might start.

Re: 35 horse johnson 1980

well..i,m off to work for the day....can some one tell me if the little sqare plastic thing with 2 large electrical connections and 2 small electrical connections ,located next to the starter is the solenoid?....also i have been given a parts engine along with this engine. according to the serial #its an 82 35 evinrude.it has starter motor and that same square plastic thing next to the starter...only thing is the 2 small electrical connections on this (solenoid?) are on the botttom and not the top.are these (solenoids?) interchangable?

Re: 35 horse johnson 1980

From your description it sounds like your starter solenoid. And yes.

Re: 35 horse johnson 1980

little bit of an update....bought a compression tester and top cylinder was 112 and bottom cylinder was 104 psi.not as close as i was hoping,but i think it is well within the 10% i hear about on the board all the time.so ...i have spark and compression....it looks like i need to look closley at the fuel system....

Re: 35 horse johnson 1980

okay.....its alive!got her purring like a kitten by jumping from positive on battery to the starter wire on the starter....now i,m going out to swap solenoids from my parts motor.....

 

[diggerdan17]

Re: 35 horse johnson 1980

swapped solenoids and still won,t engage starter when key is turned.got my multimeter out and when ignition is on but key is not turned all the way to start posistion i get 11.4 volts on one side of the solenoid....so then i got my son to turn the key all the way and the reading went down to zero on the volt meter...does anybody know what this means?is my ignition box with the key toast?or do i just happen to have 2 faulty solenoids?

Re: 35 horse johnson 1980

turns out it was just corrosion built up on the battery clamps.ya i know its the first place i looked.i swear to god they looked fine.i went down to the auto parts store and spent a wopping 1.59 on 2 new battery clamps....and presto...turned the key and she was alive!<br />now the only bugger is that i have to wait a week to 10 days for all the ice to come off the lakes up here in canada ....so i can try out my new toy 14 foot starcraft with 35 johnson.<br /><br /><br />by the way, ty to all who replied ,i love the helpfull people who take time out there busy day to help make other peoples day better.this forum is superb.
