Early 90's Mariner 115 mechanics

[camomanbg]

Looking for suggestions for a mechanic that would be knowledgeable and willing to work on an early 90's Mariner 115 preferably in the Rochester area.  Having a fuel supply issue, thinking an air leak and it might possibly be the fuel lines on the motor (I replaced the supply lines, fill line, etc on the boat this winter). The boat starts great, idles great, trolls great but sputters and bogs down when I try to get on plane... sometimes but not all the time.  Sometimes it'll run on pad full speed for 1 min other times 10 mins.  But usually it'll bog down after getting up and run at 20mph, sometimes I'm pushing water at 10mph.   No consistency.
