Just purchased a used sailboat with the Yamaha T9.9... 4 Stroke. Motor starts fine...spits a little water then nothing. Seems to be dry; then starts gurgling and finally spitting a steady stream; then stops spitting again...Cyclic.. I rebuilt the water pump. New impeller, etc.... Everything is in solid. Still the same sympton... I can disconnect hoses from the power head and get no flow to the pee-hole...<br /><br />Any ideas/suggestions would be appreciated... Owner said the motor was very low hours.... Looks like new...
