SOURCE: 9.8 hp mercury outboard shutting off in low idle speed.

My problem ended up being the spring on the reed valve being weak.But at the same time and while I had already had my carb broke down I took a can of carb cleaner to it and cleaned it. In order to replace the spring on reed valve you will have to buy a new one, but don't worry I only payed about $6.00 for mine. You may also look into replacing your primer bulb if you haven't already because may allowing air to build up in your gas line while you are basically idiling.Once you get the carb straightened out you may have to reajust it again. If I might be able to help you again you may contact me at j_speaks@yahoo.com.

SOURCE: My mercury 35 hp outboard motor idle's fine but won't run

While at the river try to adjust the fuel air mixture. When you are on the water it puts the engine under a load and if that dont work then dont be afraid to bump up the idle stop screw slightly.

Mercury 150hp Optimax outboard


clean the connection on the back of the tachometer and on the sensor in the engine. If the engine remains at 2,000 rpm and won't go faster, you need a marine engineer with diagnostic equipment. That is a big engine on an 18 foot boat!

Why does my mercury outboard idle perfectly but stall out under load?


Your carbs are probably dirty. Remove the carbs and clean out all jets and passages with carbcleaner and compressed air.

Why won't my mercury optimax 150 outboard start?


your owners manual should tell you what the beep code means.or call a dealer and ask them.

Why won't my Mercury Optimax 150 outboard start up. Engine turns over just fine, and there's 2 beeps to the throttle box.


I usually do cars and trucks, but if you are getting an electronic beep, you might go online and refer to an engine Manual for what you own. You may have a low oil lockout for the crankcase on a 4 cycle or a low oil cutoff alert for a 2 cycle with an automatic oil feed mixer. Some transition of inboard-outboard technology to outboards can include tilt lockout so that you can not start up in gear. Most prevent the starter from turning, but could keep the engine from firing if they want to wire it that way. With the "beeps" it would seem to be a Code.
