1996 Johnson 50hp J50TLEDS
Okay. Engine would turn over and start, but usually needed to add a little throttle quickly to have enough RPMs to idle. When switching in to gear you have to move quick and give it some throttle so it wouldn't die; but it ran and was dependable at doing what it did.
It had been quite a while since I'd changed the plugs, so I did. When I pulled the old plugs it definitely looked like I got my money's worth out of them. I put the new plugs in and put a fuel treatment in the tank as I topped off about 10 gallons. Put the boat in the water, started up really quickly and nice with just a quick choke. Buddy drove it to the dock about 10 minutes away and tied it up.
Next day, got a call from buddy saying the boat was running well at low speed, but cutting out and stalling at upper RPMs to wide open throttle (WOT). Once before this happened, figured it might be the inline fuel filter. It's one of the glass ones with a screen that can be cleaned, not the throw away kind. Explained to him where it was and what to do. He seemed uncomfortable with it; either way we are on to the next day.
Boat runs fine again in the morning. For a little while. Then I get a call that says the boat is cutting out at higher RPMs again and that he has to give it more and more gas to start each time and that he just made it back to the dock and had to basically run it at WOT just to make it back to the dock and that it didn't have much power. I'm thinking 'I wonder how many times he's been starting it and hope he hasn't done any sever damage'.
I go check out the boat right then, it won't start unless given A LOT of throttle and when it does it sounds very bogged down, almost like it's running on one cylinder or like an engine sounds when it's about to be flooded out.
SO today, I pull the cowling off and it looks like some oil might have been leaking a little bit from the upper of the two plugs. Pulled the plugs and that top plug has some oil on the threads. Pulled the lower plug and that one looks dry and like I think it should. I gapped the plugs to .030, I know I should have done that when I put them in, but didn't know. (note: The gaps weren't more than .040 from the factory I don't think). I cleaned them with some ether and then replaced them. I then pulled off the air silencer scoop cover thing on the front of the engine, in front of the carbs. I pulled it thinking I could check and clean an air filter that I've never cleaned. There was no air filter; but there was a little bit of oil in the cover.
Put everything back together, thought I'd crank it over just to see if a miracle occurred. Starter engaged the flywheel and stayed there. Didn't spin the flywheel. Thinking I need to put a charge on the battery, but also wondering why the bendix didn't retract. I manually wobbled the flywheen a little and the bendix is still stuck up.
Currently the battery is on the charger. Thoughts?
Thank you ahead of time for your time and thoughts. I can't wait to get this all solved. I love this little boat and it's been so good to me over the years.
