2001 oceanpro dies when warm.

[icancu2]

Hi all new to this forum & I am in need of some help. This is my first outboard motor and it is really starting to P*&& me off. 3 weeks ago I brought the boat up from N.C. and put it into the water started and ran fine for about 2 miles shut it down rigged some lines and when I restarted it it would not run above idle give it gas and it died. Restart let idle and after a min or so it would rev up by itself, no dash lights to indicate "slow mode" and it was running rough. Took it to a "Johnson" repair shop 400.00 later said it was a warped plastic cover causing the timing lever to stick. spark & comp great...well I just got home with the family after floating around 9 miles out in lake Erie for half the day same thing start run great shut it down wont run let it cool down for a couple hours run for awhile start running rough and die. Please Help running out of money to fix...oh this is a 2001 Johnson 150, 6 cyl, 2 stroke Thank in advance for your help.

Re: 2001 oceanpro dies when warm.

Welcome Seaworthy. I have the exact same motor and have experienced very similar symptoms. Turns out quite a few people with this motor have similar problems. Not sure if there is any one cause but, from what I glean from the various people who have discussed this recently, it is very important that timing, idle mixture adjustment & link & sync are all set correctly for these motors.<br /><br />On my motor, I can fix the problem by revving it in neutral until the motor "clears". Then I can put it into gear and take off fine.<br /><br />The reason that the problem only occurs when the motor is warm is probably related to the fact that the motor has a Quikstart feature which advances the ignition timing by 10 degrees when it is cold. Seems to make a difference.<br /><br />My motor also had a sticky timing plate. The timing sensor is attached to a rotating plate which rotates in a plastic track. I fixed this myself using fine valve grinding paste. I lapped the two surfaces into each other until the plate rotated freely (with some grease to lubricate).<br /><br />So my advice;<br /> - Check that timing is spot on (you need an anlayzer to do this properly - I can help with this.)<br />- Check that idle mixture screws are set not too lean<br />- Check that throttle/ignition are linked & synched correctly<br /><br />You'll need a service manual if you want to have a go at these yourself (not too hard). I would have thought though that a good shop should have checked these all out for you?<br /><br />Email me at Seasport1@hotmail.com if you want to discuss offline.

One more thing. There's a chance that the optical sensor could be faulty. Another member reported similar problems and replacing the sensor plus a bit of tuning as above seems to have fixed it.

Re: 2001 oceanpro dies when warm.

Man, it could be just about anything. My bet is your powerpack is going out. You paid $400 and didn't get it fixed. I'd take it back and ask for your money back. That's BS in my book.

Re: 2001 oceanpro dies when warm.

Thanks Seasport for the quick reply and I agree with you Walker about getting my money back but as this problem only seems to happen after I run the boat for about 15 min under load I was going to cut them a little slack as long as they continue to work with me at a MUCH reduced rate (free). Seasport I ordered the Manual for this motor and it should be here in a day or so. This will help me understand what advice you can give me. I have read alot of posts and you guys are great, what a great forum to help each other out. Thanks again

Re: 2001 oceanpro dies when warm.

Oh, one other thing Seasport that I forgot to mention in my original post was that the second time, after the 400.00 plastic part was that I had made about a 3 mile run into the lake and had dropped down to a slow Idle to rig my lines and after about 5 min at Idle speed the motor started "jumping around" like it was running on two or three cylinders so I shut it down. I dont know if that helps but...funny thing is that threw all of this she starts on the first touch of the key. Go Figure

 

[Seasport]

Re: 2001 oceanpro dies when warm.

Hmmm. I think Walker raises a good point. Your problem sounds a bit more severe than merely hesitating/dieing when you start off. If your motor is running on less than 6 cylinders, it could be that your powerpack is playing up when it gets hot. You can check that you are getting spark to each cylinder using a timing light on each spark plug lead. The timing cover has marks corresponding to each cylinder. You should be able to "freeze" the mark at each cylinder position. You can also use a spark-gap tester to verfiy spark.<br /><br />You could try heating up the powerpack using a hairdryer or hot air gun to see if you can cause the problem to occur.<br /><br />Another possibility is the shift interupter switch. This is a little switch mounted on the shift control lever in the motor which disengages the Port bank of cylinders when shifting out of gear. If this is faulty or misadjusted then you could be losing one bank of cylinders. You can disconnect this switch completely to check this out. Just makes it harder to change out of gear at higher revs.<br /><br />There's a good ignition troubleshooting guide which can be downloaded from www.rapair.com. This has a lot of good info on the OIS ignition system.<br /><br />Another possibiliy may be that the SLOW system is activating - in which case the engine will not rev above 2500RPM and will shake hard. This is either because the engine is actually overheating or possibly because the powerpack, temperature sensors or wiring are faulty.<br /><br />So there's a few things to check out. Good luck!

Re: 2001 oceanpro dies when warm.

Thanks seasport after reading your reply last night I did a google search on the optical sensor you had mentioned and got this www.maxrules.com/fixomcoisignition.html I think it is the same as the one that you are refering to. A troubleshooting guide to the OSI 2000 system. I got some things to check out. I tried to Idle it up on the hose lake today but the motor just wont get hot, didnt take the wifes hair dryer out but will do that in the morning and heat up the powerpack & see if I can duplicate what is going on in the lake. I did however pull the shift interupter and when I depress it by hand for a split second and kill the port side the motor still does not act the same as it does on the water. No huge shakein going on. Have to wait untill this weekend to put her in and run some tests on the lake, manual to be here Wendsday. Got the Johnson 30 HP kicker mounted today so at least I wont get caught blowing in the wind. Will let you know what I find out. Thanks all.

Re: 2001 oceanpro dies when warm.

The Maxrules info on the OIS 2000 system is lifted straight out of the book available for (free) download at www.rapair.com. Better to get that.<br /><br />Good luck. Persevere, they're good motors. Let us know how you get on.

Re: 2001 oceanpro dies when warm.

Did the download thing and just to see if they would reply I e-mailed their tech at CDI/Rapair and told them my problem..Here is the mail I got back from them..<br /><br />It sounds like the SLOW system is being energized once it (the power pack) overheats. This is an inherent problem with those power packs. The pack will have to be replaced.<br /> <br />Before you start the engine with a new pack, the stator needs to be tested. The power coil of the stator (orange to orange/black lead) can damage that part of the power pack. Check ohms between those wires:50 ohms. If possible, visually inspect the stator and the stator coils for signs of overheating, burned coils, leaking varnish, etc. Any of these issues found on the stator will cause it to be replaced.<br /> <br />Thomas 'TJ' James<br />CDI Electronics<br />1.800.467.3371 (ext. 226)

Re: 2001 oceanpro dies when warm.

Interesting. Does sound like the power pack is faulty & going into SLOW mode. However, before you go spending money on a new one you should check out a few things.<br /><br />(i) Make sure that the motor is not actually overheating. You should be able to hold your hand on the cylinder head for about 3s. The fact that you are getting no warning light at the dash suggests this is not the problem.<br /><br />(ii) Check out the temperature switches on each cylinder head (tan/blue wire). These connect to ground when the engine overheats. You can disconnect the wire to disarm the switches.<br />(Of course you'll need to get the motor to misbehave before you can test this out. Remember also that once SLOW is activated you have to turn the motor off to disarm it).<br /><br />(iii) Check out the blocking diode in the wiring harness. Apparently, if this is faulty the powerpack can go into SLOW mode with no warning lights coming on. You can test the diode by doing a conductivity test one way and then reverse the meter leads. It should only conduct in one direction. Diodes are a lot cheaper than power packs<br /><br />I guess you have the service manual by now. This will lead you through the tests.

Re: 2001 oceanpro dies when warm.

I have a 2000 150 Ocean pro that does the same thing as you describe, but I too can put it in neutral rev it up to clear the problem. I have other problems with mine, I just posted them. If I keep having problems with this engine, I will drop it in a hurry. I don't like getting towed 5 miles to the dock!

Re: 2001 oceanpro dies when warm.

Well guys I got to put her in the water today and I think that the problems I was having is gone but I have a new one to deal with. Oh just to bring you up to speed I changed out the power pack & put in two new thermostat's she did not have any before, kinda answers the question of why I could run it off the hose lake at idle for 20 min and the heads were cold to the touch!! I think the motor never senced temp and kept RPM's high as soon as I put them in ran 3 mins and Idle dropped to around 850 before 1100. Now I have same problem Seasport & Jellyvision have after running and shutdown when restart I too have to rev motor to "clear" or she will stall. Kinda smells like she may be flooding out?? Does turning the key send gas to motor for a couple seconds?? Whats the best way to get her running with this problem?? Thanks Guys you have been A world of help and saved me some money too. If you guys are ever in the Detroit, Mi area e-mail me & we will go Musky fishing in Lake Saint Clare tons of 50in class Musky to be had.

Re: 2001 oceanpro dies when warm.

Hey Seaworthy I was wondering how you were getting on. Hope your problems are mostly sorted. No thermostats eh! Previous owner must have decided that they weren't needed! Motor was probably staying in Quikstart when running on the hose - hence the increased idle rpms.<br /><br />We could probably start a club of 150 owners whose motors die from a warm start. In fact, we're pretty close now! We're sort of back where we started with this thread. Read my comments above.<br /><br />Now that you have the service manual, you should be able to work through the link & sync procedure. Checking the timing is a bit more tricky. I can provide details of a DIY ignition analyzer which I designed. Works fine. There are a couple of guys building these at the moment. Requires only rudimentary electronic skills. Otherwise you can buy an analyzer for about $300!<br /><br />Important that carbs are not set too lean. Service manual gives procedure for adjusting the idle mix. One of the guys with this problem sorted it by adjusting the idel mix and also found that some of the bolts holding his carbs on were loose. Sucking air perhaps.<br /><br />Turning key on does nothing to fuel system unless you push key in and activate primer. This uses a solenoid to pump fuel into the motor and takes the place of a conventional choke mechanism.<br /><br />Thanks for the fishing offer. No idea what a Musky is but they sound big! Do you eat them? My fishing is in the ocean. Great fishing (& boating) around here.

Re: 2001 oceanpro dies when warm.

I would like to take you up on the DIY project. My e-mail is rdunham@comcast.net I think that they must have set the idle/timing to a cold motor and may have it out of sync. The manual say not to try this without the anlayzer so if you dont mind send me the plan's. A musky is basicly a fresh water baracuda, he will eat anything he can catch & they have even been known to strike at a motor's prop. Urban legend has them hitting swimers in the lake, but I'm sure you know how fish stories go...oh by the way have you ever messed with prop selection to raise your RPM's?? I just want to go about this correctly these motor's are $$$$

 

[Seasport]

Re: 2001 oceanpro dies when warm.

I'll be in touch by email. Interesting re the musky. You'd catch a big one with the prop!<br /><br />I have messed with prop selection on my previous boat but not this one. Dhadley & others here are experts in this area. You only get 200 or 300rpm with each inch of pitch. The setup of the motor on the boat is also important. The higher the motor is mounted the higher the revs but more risk of cavitation and bad handling. There's been a number of posts around this subject recently.<br /><br />If you're around the 5000rpm mark you're not doing too bad. That's in the middle of the recommended range according to the manufacturer. I'm not too unhappy with 5000rpm. My holeshot is great. Always nice to get a few more revs though to be sure you're not loading the motor. But with stainless props running close to $1000, you think twice about playing around too much!

Re: 2001 oceanpro dies when warm.

Got the plans the other day getting my parts together hope to be able to build it next week. I contacted the prior owner to see if he had the same warm motor problems that we have (rev to clear) and he says Not! Said that the reason the themostats were doctored was to correct the warm take off issue, said that he trolled for hours and didnt have loaded plug concerns either?? This weekend weather permiting I am putting the old thermostat shells back in and see what happen's. Will let you know if that "cures" my motor. Do you know if the sell different temp stats for our motor's? The ones I bought are 165 degree. Operating temp is 125-165. I wonder if a lower temp will run better??

 

[Seasport]

Re: 2001 oceanpro dies when warm.

Great. There's a few others doing the same thing. Drop me an email if you need any assistance.<br /><br />Don't know about different thermostats. Not sure how much difference they will make to the warm start problem. It seems that the motors take off fine when in Quikstart. It kicks in when the motor temp is below 105 degrees. I guess if having no thermostats keeps the engine running colder then it might help but doesn't seem the right way to fix the problem.<br /><br />The motor should behave itself if everything (clean carbs, idle mix not too lean, timing OK, timing plate moving freely, link & sync OK) is set up correctly. Afterall, there are a few of these motors out there that actually seem to work OK However, there are enough people with similar problems to suggest that this is a weakness with these motors. Still, other than that they are great motors.
