"I recently got a 1999 25hp Ya
"I recently got a 1999 25hp Yamaha. The motor doesn't have many hours on it judging from the looks of it but it has a problem of running rough when first starting out. The motor starts on the first pull and idles fine but when taking off it bogs, cuts out, stumbles, coughs, however you want to describe it. It will do this for several minutes then clears up and runs perfect until the next trip. I have replaced the fuel line from the tank to the motor due to cracks in the old one, cleaned the fuel filter and put in a new set of plugs. Any other suggestions as to what might be the problem? Thanks"
