Newbie to boats with a question.. 69 johnson 33el

[Patrick1245]

Hi i just picked up a 14ft M.F.G boat with a 33el Johnson on it form 69, i have been trying to get it to run the last few day with no success.. at first the carb wasn't getting gas into the float bowl so i pulled it apart and rebuilt the carb, and now its not getting any spark to the plugs.. the boat is missing the ignition so i have been shorting out the solenoid to get it to turn over but cant figure out why it has no spark.. what parts should i replace? the motor was sitting for over a year.. and i plan to replace some important parts but i want to make sure the motor will even run before i dump more money into it. it sounds like it has great compression.. also i found the hot wire under the bow and connected it to the yellow wire that goes on the starting solenoid so those both have power? anyone with a wiring diagram of the motor or boat that would want to share would be awesome.. like i said i just want to hear it start before i dump money into it... thanks guys

Hi Patrick. Welcome to iboats. Just to clarify, you have a 1969 33hp outboard, correct? Do you have a model number by any chance? It can be found on the small metal tag riveted to the transom clamp. When you say it "is missing the ignition", what exactly do you mean? Is it simply not making spark, or has the magneto plate been removed entirely from beneath the flywheel? Johnson outboards of this era use the much loved OMC "Universal Magneto" to generate spark through purely mechanical means. There is no need for a battery, or other electronic components, except to run the starter motor. The good news is that as long as the compression is good (+100 psi per cylinder with both cylinders being within 10% of each other) all of the rest can be fixed with relative ease and for under $150 in most cases. Here are some handy links that can familiarize you with your motor. Give 'em a read an report back with your model number and we'll take it from there.

Re: Newbie to boats with a question.. 69 johnson 33el

Thanks for the response! By ignition I mean the turn key ignition, from what I can tell by the numbers it is a 69 33hp, ill read over those links when I get home from work and post a few pictures of the serial number to see if you guys can point me in the right direction! Thanks again ill update around 7pm est

Well I've been trying to pull the flywheel with no luck.. all bolts have been removed I have heated it with a torch, soaked it in wd40 but it won't budge... Any suggestion?

Hi!

Have you tried to remove the flyweel with a harmonic puller?

Re: Newbie to boats with a question.. 69 johnson 33el

Hello again Patrick. Make sure you use (1/4" x 20 x 3") GRADE 8 bolts and washers to remove the flywheel. The bolts that come with the puller kits are usually not strong enough and will either break and/or strip the threads in the flywheel itself. You may also need a pipe or breaker bar to help give you some leverage on the ratchet. Thees old flywheels can be pretty stubborn, so take your time and tighten the puller in small increments if need be. You'll probably hear a loud BANG when it comes free, but that's also pretty normal. My '66 33 hp sounded like a gunshot when I removed the flywheel for the first time. Keep the flyhweel nut on and back it off a few twists too. It will keep the flywheel from flying away on you when it finally comes free. Here's a handy link to help you with the job. You should be able to get any ignition components you may need right here at iboats. Good luck. Holler if you get stuck.

thank you! went to ace and got the grade 8 bolts in that size and it came off with ease with the help of a rented puller here are some pictures... what parts should i replace besides the coils.. thanks again everyone for all your help also if someone would be willing to make a little parts list they think will help the motor have a good reliable future that would be awesome.. like ive said i know little to nothing about boats and how they work.. cars on the other hand is a different story

Re: Newbie to boats with a question.. 69 johnson 33el

Hello again Patrick. Glad you got the flywheel off. The worst is over. It looks like the coils (big black plastic things) have already been replaced and look ok. If they were original and bad, they would be scorched and/or cracked. However, I would replace the points and condensers now that you've come this far. You can get a "tune up kit" which contains 2 sets of points and condensers for about $20 right here at iboats. You may also want to change the spark plug wires for good measure. If you do, make sure you get 7mm COPPER CORE wires, rather than modern automotive wires. You can usually get it for a few bucks a foot from auto stores and/or small engine shops. Use the link below to walk yourself through the job. Good luck. Holler if you get stuck.

Re: Newbie to boats with a question.. 69 johnson 33el

They have cracks and chunks missing..
look at the third picture.. also is it normal for gas to come back out of the carb when you go from full choke to no choke? I think im going to take the top half off with the coils and bring it to the nearest marina and see what parts they reccomend...

 

[kfa4303]

Re: Newbie to boats with a question.. 69 johnson 33el

Ah yes, it is cracked. No need to take it to a shop. It uses standard issue OMC coils, points and condensers. You can get 'em all right here for about $20 each.

Re: Newbie to boats with a question.. 69 johnson 33el

No. You should not have gas coming out of the carb. If you are, that's a tell tale sign that the float needle is stuck. You will need to remove the carb and rebuild it using the carb kit found below. Here's a link that can walk you through the job. It's for a slightly different model, but all of the steps are the same. If your carb still uses the original float you'll need to replace it with a new plastic one as the old cork versions can/will break down over time and clog the carb passages.

Give this link a read to familiarize yourself with all the basic systems of your motor and its operation before you go any further, and be sure to only repair one aspect of the motor at a time. Once you have confirmed that it is fully functional, move on to the next job. If you try to fix too many items at once you'll only end up chasing your tail and wasting time, money and effort. Confirm compression (+100 psi with both cylinders within 10% of each other), Confirm strong blue spark capable of jumping 1/4" gap by setting the points to .020" and spark plug gap to .030", Confirm fuel delivery to motor by rebuilding carb and replacing old fuel lines as needed)

Re: Newbie to boats with a question.. 69 johnson 33el

Thanks! well found out some bad news today.. it has a compression leak.. and it is coming back out of the intake... i did a compression test and both cylinders were only at 35psi i am thinking it is a head gasket issue? because i put some oil in each cylinder and the psi did not go up so that eliminates the rings.. so i guess its coming way apart tomorrow

also anyone know where i can get a gasket set for this motor? since im pulling it apart more than i had planned might as well redo some gaskets...
thanks guys
or just a head gasket

 

[Patrick1245]

Re: Newbie to boats with a question.. 69 johnson 33el

Also the reason I am thinking its a head gasket is because on the compression stroke if you put your hand on the intake on the carb you can feel and hear air comeing out am i right?

Re: Newbie to boats with a question.. 69 johnson 33el

well found out more bad news.. pulled the head and found out it has tons of piston slop.. yippy time to sink the pos
