Hello all,

I'm Paul and new to outboard motors.

I've got a Johnson 115. 4 cyl.

Cold start, no problem. Top end is great.

Once the motor gets hot, if I shut it down, I have a hell of a time getting it to idle again.

I have to fast idle it and Choke it to get it started when it's hot?! Then when I drop the idle so I can engage the prop. it quits! Very annoying. Takes many attempt to get under way again.

Any suggestions from you pro's would be greatly appreciated. Carb kit?


Also, I need to find the specs for the motor. I'll probably buy the manual when I've a few extra bucks. Model J115TLCTE, Serial J5842624. I don't even know what year the motor is... Maybe Google?

Anyhow, would appreciate any input.

Safe boating,

Paul

Thanks for the link. Can't afford the manual at this time.

Tried to do some research before asking more dumb questions.

Understood all except linc n sinc. Any more on this, please...

Thanks again,

Paul

also check your spark when it is acting up, could be coil or power pack heating up and failing. link n sinc, is a step by step procedure, different for each motor, the manual has great instructions.

Paul, do a search on "sync" and you'll get some background. Honestly, tho, you won't be able to tune that motor properly without the manual(s).

That said, my '97 (which IS in good tune) likes a lot of fuel when starting either cold or warm. Hot restarts are never a problem, but if it's been sitting for more than a half hour or so, I need to follow a process to restart it. I also use the fast idle lever every time. There's no harm in it- that's what it's there for. It took me awhile to learn the "procedure" for starting and warming up my particular motor before I put in in gear, but now it almost always starts on the first revolution, and I never stall it. I just need to be a little patient while it settles down.

I grew up in the days of carbureted motors (cars, mostly), and they all have their little quirks as they get older.
