Re: fuel problems
All kinds of **** from collapsed fuel lines to carb full of funk. Just because a motor revs in neutral don't mean squat. Start with the carbs and work back to the tank.
Re: fuel problems
i got a guy thats going to clean the carbs tommorrow. when i get it back together tommorrow will i be able to hook it upto the water hose, and tell if its bogging down or will i have to put it back on the river i was just wondering because thats a twenty min trip for nothing if its the fuel pump? ill keep everyone posted

Re: fuel problems
You will probably need to take it to the lake to test.
Pick up one of those round vacuum-pressure testers from a auto parts store and a T fitting that will fit your fuel line. Install it in right in front of your fuel pump if it reads more than 4" of vacuum you have a restriction problem. If that's good put it on the pressure side of the pump, it should be more than 3psi. Again this test is better on the water with a load, the first merc fuel line problem I had was fine out of the water but would collapse under a load.
I would look into a ignition problem, check for spark on all 6.

Re: fuel problems
I had a bad high speed coil on my merc last summer, but at work last week I had a omc with a bad powerpack that cut ignition to 1 cyl. it didn't sound that bad uot of the water but would fall on it's face in the test tank.
