*Final Update*
Alright I have finally got this motor running top notch. The problem came back randomly so that is what had me looking further into it. I figured out what was going on with the wiring so I wanted to post a final update so this thread will be complete. The culprit was simply bad...
That is pretty much the only conclusion I can come to as well. I started to unwrap the entire wiring harness coming from the switch box to the coils just to see. The coils are old, look to be original blue ones with mercury logos on them. I'm going to go ahead and put a new set on with some...
Finally made some progress with the classic 50, removed and cleaned all connections at the coils. Not exactly sure what the culprit was yet, but was able to get this thing running at top speed yesterday. One thing to note, the previous owner apparently replaced the mercury tilt switch. This is...
Just wanted to pop in and leave at least a small update. After installing the venturi's back in these carbs it didn't seem to make a difference, but that's only because the actual problem hasn't been solved. I removed the flywheel revealing a "red" stator with a date code of 1998, once I removed...
I'm guessing the techmate has add ons for outboards as well ? I'd like to be able to scan the later model Mercury and Yamaha EFI motors, maybe Honda and Suzuki also.
Does anyone have any experience with the Rinda Tech Mate Pro scan tool ? Also is there any other scan tools on the market for a reasonable price that would allow me to scan later model outboards to check and clear codes ? Thanks !
I can assure you I'm not your average bear, I will figure this thing out eventually and post the results right here for everyone to see. Whether it is something I simply failed to do correctly or if I find a faulty component.
Got another small update, slow progress is better than no progress !
I finally pulled the lower unit back off last night and checked to make sure that exhaust tuner wasn't plugged, and it appeared to be wide open. Pulled the carbs back off and installed the venturi in both of them, everything is...
@racerone, I have discovered another problem that may be at least partially contributing to this. Just wanted to give you credit for mentioning it. I was reading another forum thread where a guy had a similar problem with his classic 50 and you mentioned the boost venturi in the carbs. These are...
Just a quick update, didn't get around to checking that max timing. Last night I double checked my firing with my timing light and revved on the engine this time, number 3 cylinder spark is cutting out briefly and coming back in. Looks like I may actually have an electrical problem after all. I...
Thanks for clarifying that, much appreciated. I will do my best to check these things this afternoon and report back some results in the morning hopefully !
