Try swapping coils from the good firing bank to the other side, Unless something got loose coming off the power pack, check all your connection and make sure there is no short some where .

Also check the ground it's clean with no corrosion, You might have to do an ignition output test if non of the above works.

The coils are connected as one unit. I may be misunderstanding the reply here. I dont see how I could swap the coils the left and right are an attached coil it appears. Its the entire right/starboard side that is not sparking all three spark plugs on that side are not getting spark, the port side is sparking fine, all three spark ok.

Thanks. I checked removed the yellow wires from the stator to the powerpack. Still no spark. Crap

Why did you do this? The test is to disconnect the rectifier's yellow wires.

These two wires correct? Its a plug I meant Stator to recifier.

No spark on one bank of cylinders

1.Using the piercing probes and DVA adapter, check the resistance and DVA voltage for the bank without spark on the 6-pin stator connector while connected as follows:

Note: If the power pack has no spark on one bank and the readings are good, replace the power pack.

1.Disconnect the 5-pin connector on the port side of the power pack and see if the spark returns. If it does, use the fluke meter set to ohms and see if the black/yellow or black/orange wire is shorted to engine ground. Check to see if the shift interrupter switch is located in the circuit where there is no spark.

Over looked it's a looper 60 degree where's coils as you said one unit ...

Anybody else have some helpful advise. I updated my list of done no results. What about the temp sender?

Re: No spark on starboard side of engine 1993 175 looper

The temp sensor usually disables the port side cyls but try it anyway.
Ground it to the block to test the buzzer whilst you're at it.

You have the twin coil packs, you can still swap the wiring from side to side, the primary wires from the powerpack should just reach.
Engine will be completely out of time but you're just checking for spark.
The odds of 3 coils going out on one side are ... not likely.

If the stator is ok the powerpack is bad....usually.

Did you locate the diode yet ?
Its under the hood, near the canon plug ( big reg plug), thats where the Y harness is.

I have a 1994 150hp, its very similar to yours, my manual covers the 175hp models. I had the same problem and it turned ou to be the pack.

Re: No spark on starboard side of engine 1993 175 looper

How can I test the stator?

The powerpack is new, not sure how new but the guy who owned it before me replaced it within the past 2 years.

He put the transducer for the fish finder too low at the port stern, I did not see it till we went out to test the boat, it created a funnel of water that shot straight up and over the engine cover and consequently got water into the air vents and since they are rear of the cover where the powerpack and coils are, it got them very wet. We were boating/fishing drinking too many beers and I forgot to wash the engine off. A week later when I went to start her up, she started great in the driveway but after 15 minutes idiling out of the channel she died and never came back to life. I wonder if the salt water corroded the ground connection which was on that side(port) or a coil connection and maybe fried the powerpack.

I did not locate the diode, I will look for it now, how can I tell if it is bad?

Test stator by using dva adapter on a voltmeter to read ignition V coming out of the stator.

Diodes are like one way valves, voltage will flow one way but not the other, test with a meter, should show open circuit one way and closed when the test leads are reversed.

I would take a guess and swap the powerpack out if nothing is obvious such as corrosion on wiring. The stator doesn't look like it melted.
For $130 the worst that can happen is you have a spare pack.

Sounds like a case of dumbass, leave it in the driveway, one less fool out there to worry about.

Where can I buy one for $130? Cheapest I found is $190?

Re: No spark on starboard side of engine 1993 175 looper

From my CDI Ignition school book:
"OIS packs are fed by two ?HV charge? stator coils, one for each cylinder bank Each onepowers either the Odd/Starboard or Even/Port cylinder bank. OIS packs have two kill wires on the port- side connector, [black/yellow] and [black/red]. These are tied together through diodes embedded in the wiring harness to the kill switch. Some
applications have an additional diode in the wiring harness connected to a shift
interrupter switch. The shift interrupter switch kills one bank during shifting to reduce
Rpm and help the gears engage smoothly."
If disconnecting the "kill" wires did not help it a stator/pack problem. Looking at your pictures posted the stator charge windings(battery) are discolored (hot & some melting) and rectifier is aftermarket(no purple). Test the stator charge windings(to pack) with meter or flip the odd/even wires on connector at pack.

hehehe, he's posting what some of us are thinking, the tendency is to buy a boat and run the snot out of it without regard for maintenance, I did that when I sank my first boat yrs ago.
When I got my second boat I decided to it by the book, first thing is to get the book. The factory service book is great, take a look on ebay for used manuals, not seloc or clymer books.
www.outboardbooks.com
GEt organized , get the engine completely in order, its your lifeline out there and out there is unforgiving.

then when posting for help, give all the info up front, model number helps everyone look up parts for you.
I got a sierra powerpack, not as good as CDI but cheaper.
My mechanic ordered it from a mail order marine part place but iBoats sells them too. I had hired a mechanic I found on craigslist for a day and we went through everything, cost me $180 and I learned how to troubleshoot it plus complete 100 hour maintenance.

The fish will return.

Re: No spark on starboard side of engine 1993 175 looper

Thanks everyone. I rebuilt a 1999 Bayliner recently so I have the skills when it comes to I/O systems. I rebuilt the engine top to bottom, outdrive and transom assembly. Then I got a good offer for her so I sold it, I wanted a bigger boat with a cuddy that was setup for deep sea fishing.

I have never owned an outboard so this is all new to me. I am learning a great deal as I go though. Trust me, when this is fixed I will baby it and maintain her like she is my girlfriend out there on the water. I will also give back my knowledge on these forums.

I inherited these issues from the previous owner who did not know anything about boats, but tried his best to get the engine in order.

Sounds like my powerpack is shot., again I am now wondering, why it was replaced with the blue version vs the gray one that was originally on it. Anybody know which one is best for this enigne. I dont have the model number, the plate was not on the engine so that was the first big challenge (figuring out the year of the engine), I deducted it to be a 1993 175 60 degree looper from feedback given by other on this forum and the manual which I do have. Its not that good though for troubleshooting.

Now I need ot figure out what killed the powerpack in the first place. Could the wrong wires cause a powerpack failure? I am wondering if the jass before me did not use the correct wires fo rthe new blue powerpack he bought....

I just found this article on why powerpacks fail:
http://www.marineengine.com/boat-forum/showthread.php?26539-For-Joe-Reeves-E175GLEO-Ignition-problems

My wires are: Sierra J2031
You can see them here:

I have the blue CDI powerpack and blue wires, with the QL78YC plugs I am wondering if I need grey inductive plug wires like they specify by CDI and I need to check to see if I have a gray sleeved stator assembly, I doubt it.

Can anyone help me identify my stator?

 

[heebeha]

Re: No spark on starboard side of engine 1993 175 looper

I am considering just going with the sierra version part # 18-5887 if I dont have to chnage the wires or stator.

Anybody have first hand experience with this and know the difference between the Sierra vs CDI powerpacks?

I cant find any information on the Sierra powerpack, as far as what wires and stator assembly needed to accompany it.

Re: No spark on starboard side of engine 1993 175 looper

You need the grey inductive plug wires.

This might be a problem. See attached. Windings should look like 8 o'clock one.

Re: No spark on starboard side of engine 1993 175 looper

Its supposed to look like this I guess:
