1996 Evinrude 150 Power Pack Replacement

Instructional video replacing the power pack and the location of optical sensor on a 1996 Evinrude Looper 150hp.

[@keneykkk]

I have a 2000 Johnson 150HP that having the same issue with no spark on one complete side of the engine. I have replaced the spark plugs and wires, the power pack and optical sensor, and all the coils. Still have no spark on the same side of the engine. (left side when facing the engine standing at the rear) Is there something else I should check. I bought a new stator to replace but now I'm just throwing parts at it.

[@bobbygfl]

It sounds like a ground is not connected shutting off the bank. There are three wires going to the shift interrupt switch. One positive and two negative. I would try and figure out if something is wrong there. Or the switch itself has shorted out.

[@keneykkk]

It in fact the shifter switch. I did change the power pack, optical sensor, coils, wires, and plugs. Did not fix the problem. I was about to change the stator before I came across your other video about the shifter switch being an issue. As soon as I removed the ground wire all three of those cylinders had spark. I wish I had found that video first before I spent all the money on that other stuff. But a good lesson to learn.

[@bobbygfl]

Having all that stuff replaced is probably for the better anyway! Such a great motor as long as you keep the oil mix. Mine is still going strong. It’s a 1996.

[@steveleston1848]

nice video thanks for sharing. I have a 05 175hp no spark on any spark plug, coils tested fine, how do I test the power pack? engine sounded good.

[@bobbygfl]

I do not know how to actually test the power pack. I’ve only replaced them. Wish I could be more help.

[@Hack_Nicholas]

I have a 1999 Johnson looks like the same power head you got there. did this fix your issue? the left head/bank is not firing on mine at all. my symptom was not building power, would not get on plane, would idle rough, ultimately overheated, because of all the strain on right head/not enough power to properly operate the water pump at full capability. I pulled plug wires while running and did not change anything, so I pulled plugs and no spark, test light does not show anything either. I assume you did not need the optical sensor then? thanks a lot for the video.

[@bobbygfl]

Yes it did. Hope you figured it out

[@camrendavis1650]

i know this is a old video but i have the same motor and had the same symptoms so i changed the power pack and starts up good but will not idle i have checked the shift switch rebulit the carbs new powerpack new optical sensor new plugs the only thing left that could keep it from running would be the stator any ideas?

[@bobbygfl]

I would rebuild the carbs again. My problem was a tiny piece of plastic curled around one of the high-speed jets from cross threading it. Do a complete bowl replacement.

[@osvaldotoro4780]

Hi ,i have a 1997 johnson 150hp OIS and Not firing left bank 2,4,and 6 piston. The right size are good. Firing but not hard. PoWERPACK, OPTICAL SENSOR? AND i have another question the cable in the wiring color gray and red line its for? Thanks

[@bobbygfl]

I would check the shift interrupt. I have a video on this if you search my channel. The shift interrupt switch shuts off the left Bank to make for easier shifting. Seems like it could be that

[@JWJH621]

Good video. I have a 96 150 Johnson Oceanrunner. It runs great, plenty of power, idles well, but has a random miss, any mid to high throttle position. Its like someone turning off and on the key for a split second. Any ideas. Thanks.

[@bobbygfl]

Sounds electrical. I’m not a mechanic but the power pack controls the spark, coils amp up the power, optical sensor controls the timing. I’d start with power pack. It’s an easy swap.

[@castillog8026]

I'm having the same issue, The thing is a few years ago when I bought the boat I couldn't get it to start and did some shot gun trouble shooting and started replacing things. Well I replaced the power pack because I didn't know how to test it but my starting issue was my optical sensor. Well now I have one bank not working / spark so I thought it was the power pack so i used my good know power pack that I replaced for know reason and it switched sides, from the side that was working is now not working. I've swapped them out a couple of times and with one power pack one side is bad and with the other its bad. Not sure if i should buy a new one

[@bobbygfl]

Try the shift interrupt switch. I made a video on this. If it goes bad half the cylinder banks will go out.

[@puriakeshmiri7208]

Great video. I purchased a 1998 90hp Johnson OceanRunner. I replaced the power-pack and just ordered an optical sensor. It doesn't have any spark and was told that will take care of the issue?

[@ct1762]

I know this is super old, but it could also be your senor and/or charge coils on the stator which is why you need the FACTORY service manual and a cheap DVA adaptor/multimeter combo to pinpoint. the last thing you want to do is blindly replace parts!

[@bobbygfl]

Hope you figured it out. Thanks!

[@dustinjohnson8837]

So I’m having the same problems and I have that exact setup. Can you show me how to test my power back to make sure? I have a meter what should I check?

[@ct1762]

shift interrupter switch shuts down a bank of cylinders (port or starboard depending on year) so it could be a cable out of adjustment or going to ground. get a DVA adapter for your multimeter and start testing the stator . there is no direct test for powerpack as it's a process of elimination. check ground kill wire at the pack to see if shorted to ground.

[@bobbygfl]

I’m not sure how to check voltage or if it’s worth the effort to do so. Just replace the power pack and coils would be my advise

[@cfauvel]

Am I seeing some kind of muffler on your prop? Do you know how to adjust the idle speed on this motor? Is it done by the timing like an older v6 motor is?

[@bobbygfl]

CFauvel yes and no, you can advance the optical sensor position and it will increase the idle also you can adjust the throttle cable set screw.

[@usvibuddy6525]

Hey, I have the same exact motor as you. I've had it since 09. Rebuilt the carbs twice (last time was in the summer along with spark plugs). I've always had this on/off knocking. It's not the foot it's the power head. But I doubt it's the cylinder because it's not constant and doesn't show any signs to be the cylinder. It starts at around 4000rpm when the boat is in gear. Doesn't do it in idle. And it's not in a pattern it's at random and uneven when it does it. It will always do it if I go from 5000 down to 4200 until the engine slows down and the boat reaches the speed the engine does at that rpm. Any ideas? I am going to check out the power pack and make sure all my cylinders are firing. Also does your have this sneez in idle every now and then? Mine does.

[@ct1762]

Yes the loopers will all have a slight lean-sneeze at idle, but when you did the carbs did you also clean out the throttle bodies? Also, no mention of doing the link n synch procedure... gotta make sure all throttle butterflies are COMPLETELY CLOSED at idle. Sounds like you might have a timing issue or weak magnets under the flywheel.

[@bobbygfl]

Rebuild the carbs first.

[@ivanfernandez2047]

I have a 2001 Johnson 150 hp outboard it looks the same as the one you’re working on but I’m white, it runs good for about 5 - 10 minutes and then dies and have trouble starting it again, I replaced all spark plugs, clean carburetors, new water separator, it was running good before I store it for 4 months

[@ivanfernandez2047]

I just subscribed to your channel I like your work

[@bobbygfl]

thank you so much!

[@bullfrog72401]

Good video. Assuming you did put the bolt back in the cap above the optical sensor. It wasn't in the video. You would have known it by now. Lol.

[@bobbygfl]

Ron Farrell lol. Yes. Pretty sure! Thanks for the comment.

I have a 1998 150hp. I'm having issues between 2k and 3500 rpm. It stumbles. A lot better at wot but it cant rev past 4200 rpm. What electronics should I change? Thx in advance.

[@bobbygfl]

sounds like carbs. sorry for the late reply. hope you figured it out

[@fishmandad588]

Hi my is rob , what web site did u get the power pack from because my motor is doing the same thing johnson 150 hp 1998

[@bobbygfl]

Dontae Young hi. I got the power pack from West Marine [phone] ask for Gary.

[@ralphwood5114]

Good info I have an older 175 Johnson. Been sitting for 10 years. No spark. No plastic on top. Under the flywheel is a lot of oil. The Motor is clean. Looks like it has never been worked on.the last owner said it went from running perfect to cutting out. Brought it. Home and parked. Its a Skeeter bass boat.

[@bradleypinson485]

I am interested in buying a boat and he says that the power pack is bad or the kill switch is bad he said that it would not even start but it is a heck of a deal do you think it is worth it

[@bobbygfl]

Yes!

[@castillog8026]

So did this fix your problem?

[@bobbygfl]

Yes. This power pack is still in it today and the engine is running flawlessly.

[@magne920]

Not sure how many hrs the mechanic that did the same thing to my oceanpro actually spent, but he sure charged for more than an hour.... :-) next time I am doing it myself!

[@bobbygfl]

Thanks

[@jerrythompson3918]

does that issue bring on your check engine light?

I do not have a check engine light however it would have a buzzer and no it does not set off the buzzer

I have a 1972 70 evinrude and I have a new starter and new silenoid installed and at full battery charge all I get is the click at the silenoid but no starter engage...what is the deal?

[@bobbygfl]

Check for current at the starter. If current remove starter and see if it spins when the key is turned. If yes maybe Bendex could be jammed.

Hi, what model is power pack?

It’s a CDI 113-4985. Runs perfectly. I’d replace the coil‘s at the same time. It’s not that much more money and you already have access.

Good deal. That's an easy fix. The Bendex and starter may be separate parts, if so I'd replace both.

[@joshuafoster6764]

+YOLOfotos I have to replace my pack on the same exact motor. I'm not going to change the sensor either just yet. Did you have to check timing and the S.L.O.W. function? Or are those steps not needed?
