1993 Evinrude 175 question

[jdcarter]

Guys - I've got a 93 Rude 175 that I'm having an issue with. I got this boat/motor last year at the end of season - the boat had been sitting for about 7 years well I put it in the shop got it back fished it 4 or 5 times and it did great. Well I took it out last thursday for the first time since last October and it fired right up well I took off from the boat ramp and about 5 mins into my trip it started cutting out on me and finally just went dead. Well i thought ok I've got some bad gas so i fired it back up and took off again this time just running it up and down the main channel to clear it up well it never cleared up and went dead again about 3/4 throttle - took about 25 mins for it to fire again so I took off and it seemed to do better but still missing every so often. Fished for a few hours - picked my buddy up and we were about to head to a different part of the lake - well when i tried to fire the boat it wouldnt do anything other than turn over - never fired. It turns over fine but theres nothing causing it to pop/fire. As if theres no spark. I'm thinking its the power pack but wanted some more info from you guys. What should I check? What does it sound like?

Re: 1993 Evinrude 175 question

get a test fuel tank and connect it to your motor with fresh gas/oil and a good fuel line. using a brand new fuel line will eliminate any fuel line connection issues. get new champion plugs. if fuel is not the problem(you may see some milky looking stuff in the old fuel, disconnect the lines and pump the bubble a couple of times into a clear jar.) then get spark gap tester from auto parts store $10-15, should have blue streak at 7/16 gap on each cylinder. then check kill switch and wiring. let me know results then we will move forward.

Thanks Sparkie - I'm headed to my buddies shop this afternoon after work to see what we can figure out. He got a spark tester so we'll do that first. It's got new plugs and fuel lines on it from last year - only ran on those 4 or 5 times but i'll check all of that as well. I'll report back this evening or tomorrow morning on the results. Thanks for the help!

Re: 1993 Evinrude 175 question

well definitely something electrical - no spark to the plugs. Is there a way to determine if its the power pack or a sensor of some sort? And is there anyway to bypass the kill switch just to make sure thats not the problem?

Re: 1993 Evinrude 175 question

well its not the kill switch either - i unplugged the 2 black and yellow wires from the power pack and still nothing.

The CDI troubleshooting guide found at this location usually helps: http://cdielectronics.com/downloads/troubleshooting guide/OMC 6 Cylinder Optical.pdf

great info ezeke! thanks!

Re: 1993 Evinrude 175 question

you will need a DVA adapter to use with your multi meter. google it, they are about $35 you can test your stator and power pack with this.

Re: 1993 Evinrude 175 question

ok did some more testing based off the link from ezeke above. All tests point back to the power pack however there is one thing i didnt look at and that was the optical eye sensor - i didnt check that becuase we supplied a known good 12 v to the yellow/red wire from the starter selonoid to the power pack and got nothing so we ruled it as the power pack. Sound right?

Re: 1993 Evinrude 175 question

The red & yellow wire is only active when the ignition key is turned to the start position, not run, to initialize QuikStart.

If you want a DVA adapter, They are still listed at a good price here: http://www.usatoolwarehouse.com/usatoolwarehouse/ESI-640.html

Re: 1993 Evinrude 175 question

ok i see what your saying - however when we supplied the known good 12v power to the yellow/red wire - we turned the key to the start position - nothing happened - motor didnt even attempt to turn over. Since it didnt do anything we then said ok its got to be the power pack because its not allowing the ignition to work at all. Is my thinking wrong here?

Also - step # 10 says:
10. Check the battery voltage on the Yellow/Red wire while cranking the engine. If below 11 VDC, charge the battery and
check all battery cables. A continued low battery reading could be from a dragging starter. If still below 11 VDC, disconnect
the power pack?s Yellow/Red wire from the starter solenoid and apply a verified 12 + VDC to the Yellow/Red wire. If the
engine now runs good, check the DVA voltage on the stator?s power coil (Orange to Orange/Black) as given below in Step
#13. Either the power coil or power pack is the fault.
So we tested the cranking volts and only got 9.3 instead of the 11 that we should have gotten thats why we tested the yellow/red wire with a known good 12v supply. We then tested the stator and all test were within spec. So thats another reason how we ruled it back to the power pack. Sound right?
I appreciate the help guys! I'm new to this so I really appreciate the help and patience!!

Are you saying that the starter motor did not turn to turn the engine, or that the motor did not fire when turned?

The yellow/red powerpack wire to test is the one running off of the red & yellow starter solenoid wire connected to the main harness; it should have a bullet connector. The engine should still crank using the ignition key, with the bullet connector disconnected, it just won't have QuikStart enabled.

The ignition system cannot work and fire without turning at least 250 RPM, preferably 300 RPM, so you need a fully charged powerful battery and good cables to start with.

Re: 1993 Evinrude 175 question

right - when i disconnected the yellow/red wire from the starter selonoid and supplied known good 12v to it - placed the key in the start position (as if i was trying to start it) and the motor did nothing - would not even turn over.

Re: 1993 Evinrude 175 question

The red and yellow wire from the main wiring harness to the starter solenoid is the hot wire that activates the starter solenoid so you don't want to disconnect it. If you have a OIS the same wire provides vlotage to the powerpack for QuikStart at the same time that it initializes the solenoid.

For testing purposes, you disconnect the powerpack from the red and yellow wire, but not the solenoid. The wiring for the OIS is similar to that shown in the thumbnail in this regard.

Re: 1993 Evinrude 175 question

wow didnt even see where it split off - thanks for that diagram as well!! I'll do some more testing and report back.

Re: 1993 Evinrude 175 question

ok - so i ordered the correct power pack and it arrived today (well what I thought was the correct one) - well go to change it out this afternoon and see that the sleeve over the wires going to the plug on top of the flywheel is BLUE so I look at my new power pack and it's gray. I said wait a minute - i thought the blue vs gray was the sleeve color around the power pack itself because i've seen some blue ones - so now I don't know what I've got - the right one or the wrong one. Well i look at the wires going to the stator and its a gray sleeve over those wires so it looks like it'd work (i think). I then read the CDI troubleshooting guide and it says the gray stator will work with any of the power packs but if you have black sleeves you have to use a certain one and the blue sleeve is a service replacement which changed the sensor as well.
So my question is - based off this information - am I good to replace this blue sleeve(sleeve over wires going to top of flywheel) power pack with the new one i got that has a gray sleeve over the wires going to the flywheel because the wire sleeve on the stator wires is gray?

Make sense?

Power Pack I"m removing - Part # 584990
Power Pack I'm putting on - Part # 584910
these numbers are right off each power pack

Thanks for the help guys!!!

What is your model number?
