Problem with 1 cylinder 110hp Evinrude

[gwoloshyn]

First I'm going to say how disgusted and furious I am with Outboard Exchange, LLC out of Waterford, CT. I bought one of there re-manufactured motors and having all kinds of problems. First my tilt/trim unit was leaking all over, I sent it to them and they are currently sending me a new one. Now, I fired up this motor for the FIRST TIME today, and one of the cylinders is giving me trouble. I paid over $5,000 for this motor. Unbelievable.

One of my cylinders is not firing correctly. When I run it, I get a popping/sneezing at idle speeds with a puff of smoke after each pop. If I run one side of the motor (2 cylinders) with plugs removed on the bad side, it runs great.

The spark on this cylinder will jump a 7/16" gap with a solid blue spark. Carburetors are freshly cleaned, and all jets and orifices are free from obstruction.

This motor has all new pistons, and after running it three pistons look very clean, but the bad piston has lots of carbon built up on it. The plug on this cylinder is pretty dry when pulled, and the rest of the plugs are wet.

Can anyone help me out? Because clearly Outboard Exchange is NOT returning my calls and I will have to try them back again on Monday.

Have you tried squirting some premix fuel in the carb throat on the bad cyl when running ?? Have you done a compression check on it??

Squirting fuel in the throat does nothing and the compression is 90 psi, same on all 4 cylinders. Hasn't even been broken in yet, and I'm having these problems...

unscrew the drain plug at the bottom of the carb on the bad cylinder and make sure theres gas in the bowl.

It seems the plug is getting more matched to the others the more I run it, but I still cannot figure out how to fix this popping at idle. Sounds like a fuel problem, but I've covered all those possible problems.

What happens if you squirt fuel in the other carb throats ??

Any chance the orange spark plug leads from the power pack to the coils are swapped? (going to the wrong coils on one side) It's the same as having the spark plug lead on the wrong plug. That will cause misfiring, backfiring that you experience. Check the color code of the orange power pack wires compared to the factory wiring diagram.

I have dealt with them and they are good people. They are usually closed on wknds too. You should have a warranty therfore I would not mess with it too much until they look at it.

Re: Problem with 1 cylinder 110hp Evinrude

I don't have access to a wiring diagram to find out but switching the spark plug leads around to different plugs make the motor run worst, so I don't think thats the problem.

They may be good people, but it seems to me like they like to hack things up. They sent me a control box that they re-wired and pinched all the wires between the two bosses that come together for the mounting holes. I also had to send my tilt/trim back for them to replace or fix. I'm in NY, and hauling this thing back to CT isn't something I want to do.

I don't see any mixture screws on this carburetor. What else can I try?

Re: Problem with 1 cylinder 110hp Evinrude

My plugs are also very wet when I pull them out after running.

Re: Problem with 1 cylinder 110hp Evinrude

I just ran the motor without 1 cylinder (the one I think is the problem) and it ran and idled great. There is something wrong with one of my cylinders and I'm starting to think it's timing. On this cylinder I get a deep blue spark that can jump a half inch, but maybe it's not firing at the right time.

When you adjust timing for a 4 cylinder motor, will the timing adjustment effect all 4 or is there separate adjustments for each cylinder?

Re: Problem with 1 cylinder 110hp Evinrude

The timing effects all four. As long as it's hitting on three cyls I can't see where the plug wires would be crossed.

Re: Problem with 1 cylinder 110hp Evinrude

what year is the motor? i know on mine if i knock the primer solinoid part way open it will cough every so often and shake the motor at idle. I found it out the hard way when i changed plugs and i must have accidently caught the red primer lever.

I don't know what year it is, because Outboard Exchange never gave me a year. It looks to be an 89-95 model but who knows.

The problem seems to go away for a short time if I manually turn on the red lever, but eventually floods out the motor and it stalls. If I turn the red lever off, where it should be, the motor coughs and spits at idle speed with puffs of smoke out the exhaust. Without running the problem cylinder, the motor runs fine.

Keep us posted as to whenever and what they have to say to you.

Re: Problem with 1 cylinder 110hp Evinrude

Will do, im supposed to talk to one of there guys today but who knows.

Im going to borrow a timing light today to check for spark while its running. If I dont get a strobing light will this indicate a powerpack failure? Coils are good, I tried swapping them around.

Re: Problem with 1 cylinder 110hp Evinrude

They didn't call me today, not surprised.. but I've made some developments on my own..

I did some reading today on the symptoms I'm having and decided to check out my re-circulation circuit. What I found was there are 4 check valves on the back of the motor next to the reeds with hoses leading to 3 cylinders, but the 4th cylinder, the one that's giving me problems does NOT have a nipple to accept a hose. Can anyone confirm that this motor only has 3 cylinder that have valve hoses for this? I don't know the exact model, but it's probably an 89 block.

if its part 2 on the diagram then it says 4 but doesnt show them all

Re: Problem with 1 cylinder 110hp Evinrude

Thanks, I see 4 check valves but those lead to three nipples to 3 cylinders and I am missing one on the cylinder in question.

Re: Problem with 1 cylinder 110hp Evinrude

Anyone have anymore advice? I tried putting in a new plug today but it fixed nothing.

I can't get hold of Outboard Exchange and they are not returning my calls. What should I do from here?
