Today, my wife and i were in our boat and decided to go for a spin in our pontoon boat. Has a 2001 50 horse Yamaha 2 stroke..........Well coming out of the hole it wanted to bog down but then picked up speed and ran fine...Rode around for 21/2 hours then the problems start.Hmmmmm well check the fuel filter, a little dirty cleaned it.Check Plugs firing hot. Now in neutral the motor runs ok, a little rough though. In drive at full trottle will only reach half speed. Bulb is pressurized and put in only 5 gallons of fuel to top off tanks. What am i missing?????? And what else can i check for? thanx
