Motor is a 1988 mercury classic fifty 45hp 2 stroke 4cly. Seems a little doggy at WOT like 4000-4200 rpm it maintains that rpm but feels like not moving very fast. Like we are pulling an anchor! But boat doesn't stall its just wimpy at times. Primer bulb gets soft, but not flat just soft, tank vent is open. Also i have a clear fuel filter full of gas when starting and idle around but floor it and it empty's out. You can see fuel trickling through it but doesn't stay full almost 90% air at WOT. Slow down or turn it off it fills most of the way back up!
