Does it buZz like a car? Like chevy ? Cause I didn't hear n e thing

Beautiful day but can't risk it again with the family aboard

Do codes stay stored even if battery switch it off

See the attached bulletin.

Jwool thanks so so much all that makes sense for sure..

went out this morning and fired right up
read codes had none
fuel pressure at shrader valve was 35-40
pulled tank vent hose off to blow through seemed fine.
air filter screen is nasty gonna clean that and throttle body.

but makes sense about that bulletin everything makes sense.
gonna put new fuel hose from tank to mechanical on.

being new to 502 efi coming from 454 carb it could just be the way i am operating the boat.. i do sort of let idle some before shut off but prob not enough... and the motor compartment on the 271 is super qhuit i think so that make sense block radiating heat and heating compartment.. i do open hatch before starting but probably not long enough..

so next step for me is fuel hose and try operating it differently..

but sucks i loosing great great day on the water i cant risk stalling again the sides of my harbor channel are all huge rocks.. cant risk it with current yesterday sucked.... had to jump off to save it from drifting into the rock walls...

thanks everyone for input its great help and advise after switching boats to a totally differnt stlye

love the boat though 1996 formula sr1 271 502 mag
hit 60gps(wont lie 59.8) with a 21p at about 5050 rpm and about 64/65 on speedo was my best so far think i gonna try the 14 5/8 x 23p mirage plus see if anymore top end

how do i post pic of it? wont let me

Should be able to click on the paper click and add attachment.

Cleaned air filter and intake
Got fuel hose off apears original so gonna change that to

You could also try and put a 6 gallon tank on it for a test and go out for a rip. This will take out any issue that you may be having with gas, tank.....

that sound like good plan..was gonna try to rig a 5 gallon can to vst inlet gravity feed from there to see... new fuel line today then gonna pull the sender and see if any gell or gunk in the tank..

and gonna dump seperator filter into a glass and let that sit

anyone have opinion on the whole setup 2 fuel pumps? is thier and easier better way?
