Chrysler 70 HP outboard motor dies when pushing throttle

My engine was running fine for the first few months I had this boat. Last few times out the engine starting losing power. Starts fine and idles but now it dies when I give it throttle. Fuel pump is working fine, new wires and plugs, cleaned points. I'm stumped.

I have found that 99 percent of the time when this happens it is carb related. It is very possible that you picked a a small piece of grit or trash in the high speed jet of one, or both, of your carbs. I would be willing to bet that pulling the carbs and cleaning them will resolve your problem. I am almost positive that will fix your problem, mainly because it sounds like you've already tried everything else. I had this same problem last season, and what had happened was I left the vent open on my fuel tank, we got a shower, and I pulled just a small bit of water into the carb and that was it, she would not do anything over idle until I pulled the carbs and cleaned them. i even put the water muffs on it and let it run in the yard for about an hour thinking that it would burn the water out, but i was wrong. Anyway, clean the carbs and i think you'll be in good shape, Good Luck.

When I start my 10hp mercury outboard after priming it will run for a few seconds and then die. IF I push the throttle only button and rev it up before priming or set the low idle up higher and then prime...


Be sure to run the recommended fuel mix. most modern 2 stroke outboard engines run on 100 to 1, some times the mix is on a decal inside the cowl.

Cheers, Timo.

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.

15hp push idle in motor shuts off


First, always have the motor in water or with a hose and muffs when you run it. It is simple to fix if all the parts are there. Let me put it this way. If you know where the air mixture adjustment is on the carburetor you turn this screw until the engine speeds up at idle to a maximum rpm, then back in 1/4 turn. Adjust throttle stop screws to achieve a minimum base idle. If this seems complicated, take it to an outboard place or lawnmower shop(if you have a hose and muffs). Its a 15 minute job and will last until its changed.
