Thread: outboard issues

my 75hp mercury outboard wont start,i think it could be due to an airlock in the fuel line i prime it till the bulb goes hard, i can still see air in the fuel filter, when i release the pressure from the priming the bubble get bigger again like its under pressure. is there any way to bleed the lines? after trying to start it there isnt any fuel getting to the motor, cant smell any fuel like you do when a motor turns over for a while and dosent fire, plugs are dry, put new plug in it just to make sure.

any ideas??
