1994 Merc 75hp 2-stroke started bogging while cruising. Noticed the primer bulb was empty (not sucked in) when this happened. Replaced both filters, fuel lines, new primer bulb, and removed anti-siphon valve.
Now she only seems to bog down at mid-throttle. Not completely, but you can hear and feel the power surging. Runs fine for extended times at idle/low speed and high/WOT. No problems getting on plane if I make sure it's primed before taking off.
Is this a sign of an air leak somewhere? Could the fuel pump be failing? Or could this be something more invasive like carb or compression issues?
