1989 Johnson 60 HP won't rap under load.....

[funtwohunt]

Hasn't been run in 2 years. Checked carbs and they looked good. They were drained before stored. Put in new gas, pumped up the ball. Checked the oil injection tank, half full, pumped until ball solid. Motor fired right up. Sounded great in a barrel of water. Gears shifted O.K. etc. Took it to the lake and unloaded it. Started it right up, backed off trailer, put it in gear and throttled up a bit seemed to be O.K. Went to about half open, 3000 rpm running good. Opened it up some more in a minute or so after it warmed up a bit. Went full throttle, motor started to rap up as usual to about 5500 rpm, then it bogged out and will run maybe 3000 rpm under load. Seems to be hitting on all cylinders. Neutral it will rap 5 - 6000 rpm. Idles great hitting on all three cylinders. We kept it slowed down and pretty much cruised a bit thinking it might clear out. It didn't, then the oil injector alarm came on, we shut it down, pumped the oil ball and restarted and alarm stayed off.

Removed & Cleaned the carbs thinking they might be plugged from storage. Didn't help any.

Any ideas?

Thanks, Funtwohunt

Was it peeing any water out the telltale? I'm not sure how many rpms "Slow" mode hits, but maybe the motor started to get to hot and then went into slow mode. The oil alarm was the only one? I guess my thinking can;t be right unless the overheat horn or temp sensor arent working. Were you getting spark on all cylinders when it "bogged" out, maybe you dropped a cylinder.................

BTW if you ran it up to 6000 RPM in nuetral, that is a VERY bad idea.

Im curious, being I don't know his exact motor.

But, how do you rev it to 6000 rpm's in neutral.

Wouldn't you have to do it at the engine, don't see how you can do it any other way.

Even with my warm up lever all the way up , I know it won't reach 6k, with a load.

Even on muffs , it wouldn't be that high.

Maybe he meant 5-600 ?? I know that you can't rev it that high from the helm..........maybe it isnt possible.

Nope, I didnt take it that way...............its all good.

For a second I forgot it was 89' and was thinking electric shift (like I had), where you can move the throttle from the box in nuetral............wasnt thinking. I just saw a high number that should not have been reached with out a load and being in gear.

Possilbly overheat sensor or stator. Are you still running with the vro system? If so check the low oil pressure switch.

having some of the same ,on 89 /60hp evinrude.overheat alarm came on 2 times so took out thermostat solved that ,then put new water pump on old still good,changed any way. took carb off,clean there ,stiil run rough at idle and not all the get up on top end ,130lbs compression on all 3 cylinders tell you this so you dont throw the sink at it maybe we can help find the problems

Commander, thanks for the info. It was pumping water out the telltale hose. Sometimes at first start up it gives an alarm when the water pressure is too low. I just shut it down and restart it and all is normal. Its always done that since new. The low water pressure alarm is a on - off --on - off signal. The oil alarm is a solid one. Maybe I need to check out the water and the oil systems because the motor might be in the "slow mode". If it is, how do you reset it to normal or will it return to normal once the systems are normal assuming something might be wrong?

Also, I read below that some think it isn't possible to rev this motor to 5,000 or so in neutral, well it can be done. This is on a 1989 Tracker party barge. There is the forward, neutral, reverse lever and the throttle lever. Put the motor in neutral and you can wind up to your hearts delight. It is very easy to wrap 6000 rpm if you are not care. I don't make it a habit. There is nothing stopping you from doing so. Maybe there is a malfunction from the factory.

Anyway, back to the "slow mode" what would you suggest I check out?

I do have a lot of mechinical experience, just not on outboard motors.

Thanks, Funtwohunt

Well I stand corrected, I think.

It still doesn't sound right, that you can rev that high , at the control box in neutral.

One thing for sure , don't do so, even occasionally.

In or out of the water, or the slow mode will be the least of your problems.

Low Oil alarm is beep every 20 seconds. No oil is rapid beep. Overheat is steady alarm....
