This engine used to idle right but now surges. changes rpm and can't set idle to 960. If I do set to 960 it doesn't stay there long and surges to 2600 or more.
The nut holding linkage just above set screw for throttle link rod fell off as I watched it. At least I found it and re-applied. Is...
I had same problem with 2006 4 stroke 9.9 and after pulling spark plugs determined it was running lean.
So with engine running I changed the setting on the fuel/air adjustment by turning it clockwise(rich) about 1/4 turn and after
waiting about a minute for engine to adjust, pushed in choke and...
I'm trying to understand choke operation on a 9.9 bigfoot. When the choke is pulled out and pushed in does the butterfly suppose to close and open?
This motor runs with choke on, but dies when pushed in.
MY question is will the small primer bulb(not large primer bulb attached to gas line) get hard after pushing the bulb many times and fill with fuel?

I changed out my water pump on 2006 115 EFI Mercury and no tell tale sign when started with muffler hooked to hose.
After reading other threads on this topic, I decided to buy a big 2' X 3' Behlen water tub and put the lower unit in water
and started engine and there was the tell tale stream of...
An aside, I noticed when I restarted motor later the tell tale was pulsing. I noticed water level was down about 2 inches, I added
more water and restarted the engine and it had a strong stream, so water level is critical.
I can keep motor running with idle adjusted high but when choke is shut...
If I adjust idle screw it will stay running, but only with choke on. If I push choke in it quits. I tried to adj. choke but no change and without a tach
I don't know if the choke idle speed is to high or low. Anyway unless someone knows a fix for this I will take it to Mercury shop.
This is a...
I have a mercury 2006 115 hp outboard and just changed out impeller and gaskets.
I put on water muffler and turned on hose and started engine and after a few minutes looked
for water from pee hole. No water. If I remember there is a thermostat that needs to open for water
to circulate. How long...
I have a new boat(to me) that I need to replace, inspect water pump.
I have removed 5 bolts on lower unit but using a rubber mallet to assist
lowering unit, no go. Are there any other bolts or gatchas that I missed?
