Help with 115 Evinrude

Okay checked every connection at that bus bar. Nothing looked questionable but I cleaned everything. No change. Should I pull the flywheel to inspect the timer thing?

Well you could test it with a Peak reading volt meter, that would tell you exactly what is wrong, otherwise you need a timerbase or a pack, call me if you want 847 356 3245

Call but no answer. Will try again another time. It's Bill I am calling?
 
Hi Paul, Jimster here. I'm thinking the timer but would check output on stator also. What do you think.
 
is there a chance that the timer is covered in epoxy from the stator? or is this one of the models they did away with the stators being covered in epoxy?
 
You need to make sure you are not chasing a ghost. Sometimes a timing light will stop flashing when running on a 2 stroke and lead you to believe you have no spark. You need to double check you are on the right track. Does it stop flashing exactly when the motor starts running poorly?
When it starts missing, run the motor to 1500 and pull the plug wire in question, if the rpm stays the same then you can be positive you have found the right cylinder. I would test all 4 that way. A working cylinder will cause the rpm to drop when disconnected. You just want to make sure you are not chasing an ignition problem when it might be fuel. Only takes a minute to verify. The reason I bring it up is that none of your plugs look wet which one might if you were losing spark, and you have done most of the usual suspects on the ignition side. Many times I have chased an ignition problem when it turned out to be fuel, and vice versa.

Understood, and thank you for the advice. The picture likely doesn't do it justice, but the top starboard is washed. It is wet and glossy while all the others are a dry brown color.

It is literally like a light switch. About ten minutes in to a cruise the rpm's drop, you can hear the motor change, and it feels like you lost about 40 horse. You can keep cruising but it feels slower. At the exact second this occurs, the timing light stops all flashing for top starboard hole. Before hand it flashes regularly and increases/decreases with rpm perfectly.

If you then power down off plane, and try to power up again, it feels like you are missing some horse power. The engine sounds off but smooth, and it will eventually plane but takes a while.

If I idle for a while, suddenly the motor will change its sound as if the missing horse just showed back up - again like a light switch. Suddenly it's all better. The timing light also turns back on and away we go until it is hot again - usually about two minutes at this point.

Bill suggested that the two power packs interact with each other via the kill circuit and it is an easy test and worth the time to disable that circuit by unhooking one wire. I am going to try that tonight. The thought is that the other power pack (port side) may be at fault and causing the starboard pack to act up. I will let you guys know the results of the test. after work.

Again thank you all for sticking with me through this mess. You are VERY appreciated!

Don't know. If the power pack test fails I think pulling the flywheel is my next step. I just don't have a socket big enough... it looks like 1 1/2 inch nut.

The socket is a 1 5/16" give me the part number off the timerbase and I will send you one

Thanks! I couldn't test it with the kill wire undone last night due to weather. Going to try again tonight.

If both power packs prove good, I will pull the flywheel. Thanks Bill!
 
Was having a beer :cheers:or two or12... It is hot out and was thinking it could be the ignition switch heading south?
