I have a '99 Johnson J115PLEEM. I believe that it's the 1726cc loop charge motor. I have no idea how long it has been sitting but best guess is 2-3 years. I've been rebuilding the rest of the boat and have finally gotten around to the motor. (I know... should've made sure the engine was fixable first, but oh well.) I'm pretty mechanically inclined and think I know what the issue is, but having never worked on one of these before thought I'd ask for some suggestions. Here's what I know so far...
When I purchased the boat in October of 2017, it did immediately start and stayed running on what sounded like 2-3 cylinders. This was before I tore the boat apart and found that the fuel in the tank looked like this...
I'm guessing that sucking this mess into the engine likely plugged some things up. I removed and cleaned out the 30 gallon fuel tank which I am currently bypassing and running off of a one gallon can of fresh fuel and oil at a 50:1 ratio instead. I also added a bit of Seafoam to the mix.
There is new fuel line from the one gallon can to where it enters the engine cowl.
It has visible spark on all four plugs, which are new and gapped to spec at .030
Compression is good on all four.
It has a new battery.
This was the procedure I used to attempt to start it a few days ago:
1. Placed new fuel line into the one gallon can of fresh premix.
2. Pumped the primer bulb until firm.
3. Pushed the key for a second or two.
4. Turned key to start
The engine immediately started and then quit a few seconds later. I repeated this several times but the most I could get it to run is about 10-15 seconds. I still sounded like it was running on less than all four cylinders.
So, my diagnosis is, "needs carbs cleaned and rebuilt". Rebuild kits have been ordered. Any other ideas?
Another question I have is, where do you connect a remote start on this motor so that you can turn it over back by the engine? The starter solenoid appears to be located underneath the starter motor, but I could only see where the main cable from the battery attached to it. I didn't see a smaller 12v trigger from the ignition switch. I'm guessing that it is maybe up under everything where it's hard to get to?
