When I pump the prime bulb going to the Yamaha<br />150 OX66 Saltwater series it never get firm.<br />My other motor is the same and the prime bulb<br />pumps like it should.<br />I took the drain plug out of the vapor separator tank and pump the bulb and fuel comes out like the book says it should.<br />I just don't get the prime bulb pumping right.<br />Looks like Im not getting fuel into the fuel filter bowl.<br />Oh I just put the new prime bulbs on both motors.
