outbard troubles

Postby Mike the Fox » Sat Mar 01, 2014 6:26 pm

I've got a 1998 Johnson 60hp on my boat. if it sits for a week or two between using it, it starts hard. it will crank, fire, then die. eventually it will get going and then start and run fine all day and even the next. it always gets fresh fuel, I prime the bulb until hard, and it has a new fuel filter. it just started doing this and its pissing me off. any ideas?

Ethanol in the new gas. Dirty carb causing hard starts. Probably struggling getting fuel and/or air. Give it a good cleaning and will probably start much better

Dirty carb would be my guess. I would guess that over time the motor floods causing the hard start. Over a few days not enough fuel dumps in to cause a problem.

If it is gonna sit for more than aday or 2. Pull the gas hose and run it dry. Keep's the carb float from getting gummed up.

Do not do this as this motor has the vro on it and will still pump oil in to the carbs thus making your problem worse.

Bad Idea. 2 strokes rely on the oil in the gas for lubrication. Run it lean and you are running it lean on oil as well.

Clean the carb like already said, also run non ethanol or stabilizer if you aren't going to use all the gas within a couple days

Spend ~$25USD on a can of the BG 444 and pour it into your fuel tank. Get the engine to idle and spray several shots of Sea Foam into the carb intakes while reving it up a bit.

Did this to my Tohatsu (which began to develop similar symptoms) and it started/ran fine (this season) in temps down as low as 2 degrees fahrenheit.

Also, instead of running the carb(s) dry at the end of each run, leave the line hooked up and every 3-4 days, go out and squeeze the prime bulb until it gets full as this will keep fresh fuel in the carbs.

I also keep Stabil fuel stabilizer in the tank 365 days of the year as some gasoline that is sold as ethanol-free...ain't.

The OP's problem sounds like a weak fuel pump to me.

Won't hurt the engine at all, not if you do what most do and let the engine just run at an idle after pulling the fuel line. When the oil /fuel runs out, the engine stops. Instantly. No damage. Besides, there is plenty of residual oil left in the bearings to let the engine die under no load. I always do this, have for decades. No problems.

One other item...check the entire fuel line for a pinhole/crack and/or bad connector(s) as you may be pulling air, plus check the primer bulb (if it doesn't pump up in 2-3 squeezes) as sometimes they start to fail internally.

I got new problems now. Lost fire. I've narrowed it down to either the stator or power pack. Shop tells me the only way to diagnose is with a dwell meter. Anybody been through this?

Cdi electronics has a trouble shooting guide online that can walk U through testing it. Also Just look at the stator if it looks like some nasty stuff is melting out of it then it's a stator. This doesn't always happen but it's easier than testing it.

So I bought a stator and power pack. Put in the power pack and it fired right up. Took it over to lake, put it in and it wouldn't start. Messed around and finally it started. Ran fine all day. Tried it a couple days later and no fire again. Tried it a day later and it fired right up. This thing is driving me nuts. My stator looks ok but I'm gonna put the new one in for good measure. Almost seems like I got a bad wire somewhere.

Try disconnecting the kill wire(black with yellow stripe) at the pack, just remember you will not be able to turn off with it disconnected, hook it back up to turn off. Could be a problem with key switch or wire.
There are still things worth dying for and 1 of those things is freedom.

That's a good idea boatman. I've wondered about the key switch

It's had plenty of new plugs. I put the stator in and now it's firing up quick. Waiting for my water muffs and a new water pump now

Well it did it again. I ran it a few times with no problems and now I don't have any fire. It's got to be a bad wire. Does anybody know where to find a wiring schematic?
