I have a 1999 135hp merc on a 21' zodiak that stalls when i bring it up. It stalls at arround 1500-<br />1800 rpm this is the second engine that has same problems. if you squeez the priming bulb<br /> when it starts to stall it climbes through the bad spot and achives full power. since its the second <br />engine and the same boat I assumed that it had to be something in common i.e. the fuel sys. I belive<br />that I have checked everything, pick up tube, anti siphon valve, new fuel lines,fuel filters,priming bulb,<br />and I ran it strait from a 5 gal can to no avail. <br />
