Why does my 8 hp honda outboard decide to go to full throttle

This engine runs flawlessly but sometimes, on three know occasions, it races to full throttle, independent of throttle linkage. The only cure was to turn off the key. It happens in gear.

SOURCE: 35hp Johnson evinrude outboard not running at full potential

Hi, did you buy your engine used? Sounds like your gonna have to get the carb or carbs cleaned. Its possible you could have a stopped up fuel filter, or not enough spark but i am guessing its gonna be the carbs. They got some gunk in em i bet. Probably old fuel turned to gunk from setting up. I had the same problem on my 40 horse.

You may simply need a new fuel cap,vacuum in the tank will rob your fuel and stall it engine,try taking off the fuel cap and see how it runs.If this does not help you may need a new fuel pump,which runs off of crank case pressure and should take over from the choke once the tractor has started.

How do l fix an outboard motor that runs fine for about 5 minutes at full throttle and then abruptly stops and will not start until it sits for awhile?


Check that the priming bulb is fitted with the arrow pointing in the directions of flow to the engine. Make sure the vent is open on the fuel tank. Check all fuel lines for kinks or blockage. If none of that fixes it, you need a marine engineer to check the fuel pump and carbs.

1993 Johnson outboard while running good will go from full throttle to barely running sometimes 5500 to 2500rpm. Carburetors rebuild gas lines good and good spark.


If your boat has a inboard tank check the Anti Siphon valve. Try to run the outboard on a separate fuel tank to isolate the fuel source to see if it is the boat or the engine. A clogged vent line will also do that.

Full throttle


check when its on full throttle that the carb butterfly is at 90deg and not over as this will reduce throttle but max advance on ignition !

Have 115 Hp mercury outboard motor missing at full throttle and on idle. At mid throttle it is running fine. Any Idea what the problem could be. Thanks, Milton


Have your spark plugs changed AND carbs cleaned and adjusted.
Usually that can also be caused by a seized advance system ( plate under the flywheel, commanded to turn with the throttle linkage... )

Honda 125 nsr 1990 wont idle and engine races


sounds like your throttle cable might be frayed or broken, when you pull the throttle and let go does it go back on its own? and can you here a clicking sound when you close the throttle? If you could send me pictures of the carb how every thing goes in and take it apart and take pictures, that would be helpful.

Ran the engine way too hard


Most of the time when this happends it has to do with valve train like broken valve spring, or bent valve , or even a bent push rod or colapes lifter, or rocker arm. At any rate i think your problem is in the valve train.
