bought boat in may 2013. ran fine on test drive and first month n a half ive had it. did compression test before i bought it. 115-120 all 4 cylinders.

was fishing a tourney last nite and couldnt get up on plane. tried a few times but just didnt have the upmh to get going. pushed in the choke aka enricher on the key and she took right off to wot 5500 rpm. when i lrt off she bogged down again. the engine idles fine and runs fine at 3000 rpms. had to run back to weigh in at 10mph after dark. so i think this is a fuel issue. fuel filter is on order. gonna change line from bulb to motor as there is some cracks. could it be sucking air? any help is appreciated! thanks fellas!
