I have a 115hp Mercury outboard, an in-line 6, on my boat that I just rebuilt the transom. It sat for a long while before I rebuilt the transom. I took it out this summer to run it and it worked well except it wasn't at full power the whole time. Seems like it was at 2/3 power while I had the throttle all the way down; then moments later it was jump up to full power (from what I could tell) and run a while. It ran smooth while it was running, just not at full power the whole time. I figure the carburators probably need to be rebuilt. Is this a do-it-yourself job? I change the water pump impeller last year myself so I can do somethings, but timing and aligning things up just right scares me. Any advice?

Thanks!

It's a do it yourself job as long as you have a manual. Buy one at "http://www.outboardbooks.com/".

That's not a difficult job... The devil is in the detail. Pay particular attention when you put them back on to the linkages between the carbs. Make absolutely sure that all 3 start to open at exactly the same time. Other than that, just work clean and replace the manifold gaskets.

BTW, these are my favourite engines, I love them. Treat her nice.

Hokie, You may have a fuel pump issue instead of, or along with your dirty carbs. To determine this, have someone pump the primer bulb while running at high speed. If the manual pumping of the fuel keeps the motor running at full speed, rebuild the fuel pump.

Thanks for the advice guys. Sounds like a good winter project. I found that taking lots of pictures helps me get things together back right.
