2000 150 hp johnson

I don't want to sound like I know more than I do. I am definitely not and expert. This 70 is the first and only outboard I've ever had to lay healing hands on. I know that your 150 is a different beast, but I would still check out the stator and do some other creative trouble shooting before replacing more parts. If you don't have a service manual, you are definitely going to need one to trouble shoot this yourself. Having a mechanic that understands the inner workings of the powerpack and quirks of your motor and is willing to answer questions would be a great help. Just don't try to "fix" more than one thing at a time and you will eventually find the problem.

Get a spark gap tester and check your spark both before and after you have the problem if you can. A manual will tell you how to set your tester and any special considerations for your motor. I assume that you looked over all of your wiring under the cowl and checked for abrasions, corrosion, and cracked insulation.

Something else you could check would be the fuel system. Run the motor like you normally would that causes it to die. Immediately go to the primer bulb and check it. Is it partially deflated? Does the bulb pump up like normal or does it take a lot of extra squeezes to bring the pressure back up. You could be fuel starved from a partially clogged fuel line, weak fuel pump, or an air leak. You can test with a portable fuel tank to decide which side of the quick connect fuel connector the problem is on.

Another place I was able to get a good bit of help from was a forum called iBoats. I did alot of reading there, but I'm afraid that my problem stumped those folks. Of course it also stumped me and my local Johnson guru as well so I don't count it against them. I was able to find plenty of things to check for ruling out problems.

Just remember, you need 3 things to make an engine run: fuel, air, and spark. Now you just have to figure out which you are loosing and why.

power pack

I have had power packs go out a couple of times on an Evinrude 90 I owned. They can indeed go out intermittantly before they die completely, but mine had seperate power packs for each bank of cylinders as I recall. The engine would still run on 2 of 4 cylinders, so that makes me think your problem may not be the power pack.

I would look at the quick start feature or stator issues mentioned in the other posts.

As always with this group, Great advice and pretty much covers all possibilitys. Looks like I have some troubleshooting to do. Appears like this is going to take at least a 12 pack to get it figured out. . I've still have my dependable john boat so, I'm not land locked with the water temps. moving up to the fishing point.

Thanks alot everyone.

my 2000 Johnson 115 did something very similar, only differience, it would act fuel starved at mid throttle and then die. New (ebay) power pack and was good to go. You can find one somewhat inexpensively on there. I actually bought two because of the price and keep one packed in a vacuum bag on board as a spare.

I thought it was a fuel issue to begin with. BUT, After the second tow back to the landing I started thinking Power pack. Looks like thats the way I will go. New fuel system (this year) and rebuilt carbs (last year). stabil

only thing I will add, don't pay someone to do the install on the power pack......literally a 20 min install. If you are real carefull you can do in dockside, wouldn't recomend it, but it would be possible. When you get the cover off, just take a quick pic of the wiring in case you forget something, but it is stupid easy, almost plug and play.

I'm with you Autobaun70---machanic quoted $300 for a power pack + install. I can pick one up online for less than $200. The install does not look too bad at all. Take a photo & lable connections. seems simple enough. (famous last words).

Thanks to all
