Mercury 2017 115 ct.

(Childersburg. AL.)

Idles great, 1/3 throttle takeoff is good up to about 20 mph (gps) then runs on 2 cylinders.acts like starving for fuel. More throttle makes this worse. On a 24ft pontoon.

Driven 10 +miles no change. There does not seem to be a low pressure fuel pump.

built into the engine to not damage the engine
because of other problems
