    Thanks! I'll see if I can find someone with an oscilloscope to check it out.

    2011 8 HP Mercury 4 Stroke

    Which one is that? I see 2 different parts, 1 labeled coil ignition (it's under the flywheel) and 1 labeled coil assembly ignition (it's mounted on the side of the engine with the spark plug wire)?

    It stumbles when I am just cruising at 3300-4000 and from idle up to WOT.

    2011 8 HP Mercury 4 Stroke

    Hello everyone, I am having a problem that feels like an engine mis. Idles fine and WOT is good, but between 3300-4000 rpm it hesitates. New spark plugs, all new fuel lines and filter. Any ideas where I should look? Thanks!

    2011 Mercury 8HP

    Hello everyone. I have a 2011 8HP Mercury Four Stroke. I am the third owner so I don't know what might have been done to this motor before I got it. I would like to find out if it has the original carburetor. I have not removed it, but from what I can see there are no identifying markings on it...

    2011 Mercury four stroke 8HP upgrade?

    Thank you for your reply. I've read where several people have claimed to upgrade their 9.9 to 15HP. I guess that's why I assumed that they were similar. I know the specs for the 8 and 9.9 are the same, so I figured maybe there is a simple way to upgrade my 8HP. The first thing I will do this...

    2011 Mercury four stroke 8HP upgrade?

    Thank you for the reply. I think the 8, 9.9 and 15HP were essentially the same for the 2011 model year. They were made in Japan I believe with Yamaha. I have not been able to find the specs for the 2011 models.

    2011 Mercury four stroke 8HP upgrade?

    Hello everyone. I have a Tracker 1436 jon boat that I've added decks and storage to. I have lost a couple of mph due to the extra weight and I would like to get that back. I've heard the 9.9 can be upgraded to 15HP by changing the carburator. If that is true can I upgrade my 8HP by changing the...

    Won't turn off

    I turn key switch to on than press a button to start engine. That part works, but when I want to stop I turn the key switch to off and the engine keeps running?

It is above the propeller shaft and drain plug but below the full level plug.It is lower than the oil level. Is it a vent? Should it leak oil? What stops the oil from coming out of it? Thanks for...

    Too small ?

    Bought my first boat, a fixer upper. It's a 1969, 14-0 long runabout with a closed bow. Had it on the water for the first time this week. I want to use it to putter around, do some fishing and maybe pull a tube. There will only be 2 people in the boat. There dosn't seem to be much room to fit a...
