I have an 1984 70hp evinrude. Motor starts up,idles, revs up good in neutral. When I shift nto forward and excelerate motor runs poorly and eventually dies. I can put it back in neutral and it will start up just fine. This happened with the motor warmed up. Ran well going out on the lake. Did not run the motor hard. Just cruising around with the kids. It seems to also run when shifted into reverse. I did not run it to much in reverse. because, I finally got it close to the dock. I did not want to get stuck to far out. This was our first time out with this motor. Prior to this situation the motor was claimed to be in good working order. And appears to have been maintained. The motor started up fine when cold. Also idles well. Gas is fresh. Oil is not pre-mixed but comes from a resevoir. I have not checked any fluids yet.

My 50 hp did that too, and the advice on cleaning out the gunky carbs is sound, if that does not work it may have to go to mechanic and have the carb(s) removed and cleaned.
When you are done using the boat each time, before you take it out of the water, disconnect the fuel line and let it idle til it runs out of fuel and dies. That is the advice my mechanic told me, you can do it at home with the muffs on too, never run it without water running through the pump.

Start with the most common and simple causes. Check the spark plugs and the gas. My engine had the same problem and it turned out to be water in the gas. Hooking the engine to an external tank with fresh gas proved the internal tank had gotten water in it.
