Question

I dont understand why my pontoon boat is not getting any gas to the motor.?

Answer 1

Not getting TO the motor, or INTO?

Be sure (as said already) primer bulb is the right way, tank vent is open, and tank pickups aren't blocked. Prime the bulb and depress the ball valve at the hose connector, fuel should spurt out (use caution).

If that isn't the problem. you have either a bad fuel pump, or stuck needle and seat in the carb(s). Remove the fuel line from the carb inlet, crank the motor a couple of times and see if the fuel pulses. You may have a "pulse line" (will be a third hose) on the pump where it gets vacuum, be sure that is good, and not kinked.

If all that is good, trouble will be in the carb(s). Pull the drain plugs in the bottom of the bowls, crank engine over and check for fuel.

If you want to fix it yourself, go here and buy a motor specific manual for your boat;http://www.marineengine.com/

Answer 2

I can think of a few reasons why you are not getting any fuel to the motor. 1: you have a bad fuel pump, 2: if your motor doesn't have a fuel pump, then you are not getting enough suction on the intake stroke to pull in the air and fuel in this case you probably have a cracked head gasket or even a hole in the motor, 3: your intake vavles are not opening due to a rounded off cam lift on the cam shaft, 4: you have a hole in your gas tank or fuel line. Either way you should get it checked out by a boat mechanic. Hope this info is helpful.

Answer 3

i know this sounds obvious but is you fuel line connected correctly , ie if you have a primer bulb in the line it only works one way.
