1972 65 hp johnson stator timer pick up ?

[Mike Giglio]

I recently did a carb rebuild for loss of power problem and much thanks to all of those who helped. I was viewing some problems another member with an old 50 hp motor wrote in about and one of the suggestions made was to check the stator for leaking matter on the block. Well the stator is or had leaked on the throttle side and the above the carbs in the front of the motor and my motor does exactly what the other member was complaining about. It runs real well and then is hard starting and won't take any load. I have a stator that doesn't appear to have leaked on a parts motor. Should I replace the timer base and stator from the parts motor or just the stator? The parts motor is a 72 evinrude triumph. A new stator is 193.oo and timer base was around 350.oo. I'm not sure how reliable old electrical parts would be but I quess since I have the parts motor its worth maybe getting stuck again lol. Does that syruppy good goop on my block indicvate the stator must be replaced. Thanks all <br />Mike.

Re: 1972 65 hp johnson stator timer pick up ?

Mike, the parts are interchangeable if they are both 65hp motors.<br /><br />Before you go replacing parts you should find out what caused the stator to overheat (thats what that syruppy substance is an indication of) such as a bad rectifier, a bad rectifier will ruin a stator fairly quickly.<br /><br />Do you have tach? is it working or not? does the battery hold a charge? These symptoms would be an indication of a bad rectifier. if you replace the stator wihout finding out why its leaking you could end up ruining the other one<br /><br />If you have a digital volt/ohm meter you can troubleshoot many of your ign. components.<br /><br />Post back any answers to these ???

Re: 1972 65 hp johnson stator timer pick up ?

are you sure its a 72? I think in 72 it was still a hydroelectric with a battery CD ign,commonly called an amplifier, and uses points on a trigger plate. how many ign coils does the motor have ?

Re: 1972 65 hp johnson stator timer pick up ?

The 72 65hp has the timer base, stator, etc. the 85hp has the points, condensor, etc.<br />See diagrams<br /><br /> 65hp ign.<br /><br /> 85hp ign..

Re: 1972 65 hp johnson stator timer pick up ?

I do not have a tack hooked up to the motor. I have a digital volt meter to troubleshoot the rectifier? I have no objection to buying a tack and hooking it up if it will help troubleshoot. I should probably have one hooked up anyway. The one on my boat plugged into the control box of a 79 merc. i never new how or tried to hook it up when i put the 65 hp on. See I picked up a new upper half of a motor after I destroyed the block on my original motor. The new unit was supposed to have 100 hours rebuilt on it. I noticed the stuff on the block under the stator before I ever ran this motor. The owner prior to me had a jumper wire from the starter soleniod to ground, and I had to swap out the nuetral safety switch and starter soleniod from my motor. I don't know if that information is helpful at all in diagnosing what caused the stator to overheat. When I turned the key the starter would occasionaly keep turning after motor fired the motor could not be shut off by the key. This problem seems to have been rectified with the swap off the soleniod. <br />This motor is a 72 65 hp electric shift inline three with three ignition coils. <br />What are common causes of the stator overheating? Rectifier what else should I check. I thought I could just swap stators. Wrong again. Do I need swap the original timer base with the original stator or can i just change the stator. The motor runs cool when it runs. I have all the electrical parts from the original motor. The test on the rectifier, is it a pass fail or is it an intermittent thing when the motor warms up. I already pulled the flywheel getting ready to swap stators. <br />As far as the battery going down I just replaced the battery I thought because it was old. I haven't used the new battery enough to see if it is draining and it is a brand new battery. Thanks for the help guys. This motor is killing me, striped bass season is slipping away.

Re: 1972 65 hp johnson stator timer pick up ?

the stators can be swapped without swapping the trigger. the two are independant of each other. <br /> 99% of the time the rectifier is a pass/fail item. someplace I have the trigger assy from one of those 3cyl motors. the 72 65 incorperated a lot of changes from the earlier 55 and 60 Hp motors. I just cant remember the excact years they changed things. <br /> before buying parts, if you have them swapping is easy, invest in a DVA meter.it will pay you back quickly. you can isolate trigger,chargecoil and pack issues rapidly. CDI has a nice manual for testing that system.

Re: 1972 65 hp johnson stator timer pick up ?

Mike, A tach is a must I think, it can tell you alot about the performance and health of the motor.<br /><br />By the way why is the Evinrude a parts motor? what's wrong with it?<br /><br />Here are some instructions written by Joe Reeves, it was easier to copy and paste them than typing them out from the manual. Also the other motor has the same rectifier so you should be able to test that one and use it if yours is no good, then replace the stator and go from there. also be sure to have a full charge on the battery when you decide to start it up.<br /><br />(Small Rectifier Test)<br />(J. Reeves)<br /><br />Remove the rectifier wires from the terminal block. Using a ohm meter, connect the black lead of the ohm meter to the rectifier base (ground), then one by one, connect the red lead of the ohm meter to the yellow, yellow/gray, then the red wire (some rectifiers may also have a yellow/blue wire. If so connect to that also). Now, reverse the ohm meter leads and check those same wires again. You should get a reading in one direction, and none at all in the other direction.<br /><br />Now, connect the black lead of the ohm meter to the red wire. One by one, connect the red lead of the ohm meter to the yellow, yellow/gray, and if present, the yellow/blue wire. Then reverse the leads, checking the wires again. Once more, you should get a reading in one direction and none in the other.<br /><br />Note that the reading obtained from the red rectifier wire will be lower then what is obtained from the other wires.<br /><br />Any deviation from the "Reading", "No Reading" as above indicates a faulty rectifier. Note that a rectifier will not tolerate reverse polarity. Simply touching the battery with the cables in the reverse order or hooking up a battery charger backwards will blow the diodes in the rectifier assy immediately.<br /><br />Post back with any results or problems

Re: 1972 65 hp johnson stator timer pick up ?

The evinrude is a parts motor because I had a hell of a time removing an exhaust manifold bolt from the block. The one right up top near the fuel pump. When I drilled out the center of the bolt, I got a small easy out in there and snapped it. I should have just drilled a little wider and wider as I have in the past with these frozen bolts. I broke a punch in the whole and made a mess out of it. It was two wide to use a heli coil, so i put marinetek in the hole. Problem was i drilled about a 1/8 size whole right through into the block and when I crammed the marintek in the hole it must have gotten in the crank area and seized it up pretty good. I havent taken it apart yet to see if I can free it up and have the hole machined. My original problem was water in the #2 cylinder with good compression and the exhaust manifold was dripping externally. Those bolts were seized to the inner and outer manifold. what a pain and i got em all but one and goofed it up. I am a hack. I'm learning though, thanks to all of you.

Re: 1972 65 hp johnson stator timer pick up ?

OOPS, Well sounds like you got a good parts motor for ign. components anyway.<br /><br />Did Joe's instructions help on the rectifier?

 

[Mike Giglio]

Re: 1972 65 hp johnson stator timer pick up ?

Haven't had a chance to check it yet. Priorities like pumpking picking and carving. I'm sure Reeves directions will be a big help. That guy helped me a ton with my carb rebuild and adjustment & float height. <br />I have a tach question, somewhere i read on here that some tacks you have to buy an additional part to make them work with evinrude or johnson motors. I wanna get a new tach and hook it up. <br />I should test that part by tuesday, I'll post the results of the test. Thanks for the help.<br />Mike

Re: 1972 65 hp johnson stator timer pick up ?

I pulled the rectifier to test today. The red wire was missing quite a bit of insulation and exposed and brittle. The part is visibly really bad. I'll check the parts rectifier with the meter before I install it and change the stator. Should I test other electronic parts because the rectifier wire had a short or just replace it and the stator and obviously I'll check replace the inline fuse off the rectifier. You saved my stator. I would have just swapped parts and cooked up the new one. Thanks so much. <br />Mike very greatful in NY

 

[MCM]

Re: 1972 65 hp johnson stator timer pick up ?

Mike, I would install both of those parts and see how it runs, then troubleshoot other areas if necessary.<br /><br />Make sure that the flywheel is torqued to 105 foot pounds after you install it or you could risk shearing the flywheel key.<br /><br />Good Luck

 

[MCM]

Re: 1972 65 hp johnson stator timer pick up ?

Mike, just a thought but when you install the other/new rectifier you may want to wrap the wires with a little electrical tape or some other form of insulation to prevent further chafing of the wires. I did just as a little insurance.

 

[Mike Giglio]

Re: 1972 65 hp johnson stator timer pick up ?

Good Idea, the replacement rectifier has some heat shrink coating on it but i may add some tape. Thanks for all the help. I'll post how I make out when i'm done with the repair. <br />How do you torgue that thing. The nut is 1 5/16 I think and what do you guys use to stop the engine fron turning when you torgue it. I'm looking for a socker that'l fit my torgue wrench. Sears didn't have one I may have to go bigger and get an adapter to 1/2 inch for my wrench. I was just gonna crank it on, I'll torgue it. I've done enough damage my way, I'll listen to you guys. lol<br />Mike

Re: 1972 65 hp johnson stator timer pick up ?

Mike, <br /><br />If you've got an Autzone nearby they have a tool loan program, other parts stores may have same program, anyway you'll need a 1 5/16 socket as you said and a torque wrench with a 1/2 drive, to hold it while torquing I used a very large screwdriver wedged through the motor lift bracket and into the teeth on the f/wheel.

 

[Mike Giglio]

Re: 1972 65 hp johnson stator timer pick up ?

I swapped stators today and when I was putting hooking the rectifier from the parts motor up , the red wire which appeared visibly good crumbled and became exposed. I just purchased a new rectifier. I bought<br />a 1 5/16 socket from local autozone, They told me they don't loan standard size sockets, and when I got home to torque the flywheel I found out my torque wrench only goes up to 75 ft lbs. I guess thats why I should have bought the better one a while back. So all I have left to do is torgue the flywheel and replace the small glass in line fuse and I should be ready to test it out. All three stator coil looking things were cracked and leaking on the stator and the one off the parts motor looked real good. Pretty easy fix.

 

[Mike Giglio]

Re: 1972 65 hp johnson stator timer pick up ?

I got a loaner torgue wrench fron autozone and they had the 5/8 20 amp fuse I needed as well. I'm anxious for a calm day to test the motor out. I may replace two of the three coils. The # 1 coil looks pretty new. The other two look old and each have a small thin crack on the motor side of the coil. I'm gonna run it for a while first the next nice day I can, but I want to replace those to coils by the spring. Thank yo all for all of your help and I'll post the results of my test run.<br />M-ike

Re: 1972 65 hp johnson stator timer pick up ?

I finally was able to get out and run my motor today and it ran well. I'll hold off on replacing the coils. I want to thank everyone for all their patience and help troubleshooting and guiding me along the way. Now I just have to adjust the throttle cable and maybe the idle screw because the motor is stalling out, the rpms are a little to low. Now I can order a new prop for the motor. I'd like to hook up a a new tach. <br />Is there a special type of tach i need for johnson/evinrudes. I remember seeing something about having to add a part onto certain types of tachs in one of the threads. I have an old tach that used to just plug in to my 79 merc that was originally on the boat.<br />I'd like to hook up charging systtem gauge too.<br />I have the metal piece that the tilt /trim fastens too on the engine. I'd love to get my hands on a tilt/trim unit and switch. If anyone knows the name of, or the year and horsepower of units that will work with my 1972 65 hp johnson, I'll try to track one down on ebay.<br /><br /><br />thanks for all the help. It was a pleasure coming in on all three with the cover on today <br />lol.<br />Mike Up and running in NY thanks to all of you.

Re: 1972 65 hp johnson stator timer pick up ?

Mike, any marine tach with a 6 pulse setting should work for that motor, (Teleflex, Faria, etc.) no additional parts should be necessary.<br /><br />Glad to here its running
