Please describe what it does when it dies.  Does it just sputter and die?  Does it die instantly like it just turned off?  Or do you shut it off and it just cranks and doesn't start again?

Today I turned it off after 20 min and it wouldn't turn over again, and just now I tried and it still just cranks but won't turn over, I'll take a video in the morning of it trying to start... But when we were in Parker it just died out after 2-3 minutes after launch I got on the gas a little and it sputtered out... And the rest of wknd it would start when cold, but die out quick. Took to gs they found o ring in jet and I think they only ran it for a few min because it was completely dry, so they didn't hook up the hose... So today it started at home ran for a minute then started on trailer in perris before launch and then ran for 20 min, idled good but, was slow and lagged, like I said I floored it right before shut it off and I think we got to like 40 at close to 4000 rpm which is low for flooring it right?? I mean at puddingstone the speed limits 35 but I got to 50-55 few times real quick and had plenty more throttle left and old owner said right now it would easily do 60 n when jet n everything was new, 65-70 easy he said but like I said it did 50-55 no prob before but today was just lagging really bad and acting like it was starving for air... Maybe for gas but I felt like air

I don't see how a port mismatch on the carburetor flange (unless we're talking 4500 to 4150) causing a running problem or intermittent die.

What did you say Greg's guys found?

I've known Shoe for a long time,  and have heard mixed results for a while now.

It's disturbing. , that being said,  sometimes when people monkey with stuff before bringing it to a shop (not say you F-ed it up) it can be a challenge to un-fock-it.

Can you explain exactly what it does/doesn't do?

Totally hear you on messin with it, my mechanic just pulled the carb off and saw the mismatched spacer but didn't pull the carb apart, but gs knew that, I told em.. The silver plate in pic with screws in it is for quick change jets for higher altitude and gs said that they found a o ring from those plates that came off and was in the bowl I think? But the o ring was blocking the fuel, so he said if they gave me more problems they're pulling em off and putting back to stock but I really don't think that's the prob, so I bought boat, it sat 2 years before I bought it so took to gs, they went thru it, tune up, oil, plugs wires etc, everything to make it water ready and went thru it completely.. Went to puddingstone 2 weeks ago for 2 hours with old owner ran perfect, 4 days later go to Parker it dies 5 min after launch n never got running then gs finds o ring so take it to perris today, ran for 30 min but was slow and lagged, floored it and barely was doing 40, at puddingstone I was doing 55 no prob super quick, and after 30 min today I shut off to jump in water n check everything too n it wouldn't turn over n still won't it just cranks...

Hey guys, so u may or may not have seen my last post about 454 won't stay running, idles then shuts off, got it fixed, gs said o ring in jet, my big question is, my mechanic (yes he works on my classic truck not boat) but he's good mechanic lol... He took my carb apart before I took it to gs and he said a big problem is my intake manifold doesn't match my carb, I'm not a mechanic so doin my best to describe it, there's a spacer in between my carb and intake manifold, it's like an inch thick or so, and the holes in the stock spacer or bracket don't line up perfect to the holes in the bottom of my carb, I can see it pretty easily but it's been set up like this for long time according to old owner and I honestly believe him 100%... But mechanic is saying its starving for air, cause spacer holes don't line up n I need new manifold.. My question if this makes sense is do u guys agree or no with my mechanic??

Perris is cool and puddingstone cool to test n burn fuel too

I went to puddingstone like 2 weeks ago, even days are boats, odd is pwc, they don't do inspections, it's like 10-20$ and u can't go past 35 and u have to go in circle. Good to test, oh and u can't go over 12 mph until after 10 am... Nieghbors have a rule, sheriff was quick to come tell me but very cool...

Did that no water in fuel so dropping off at gs... Weird stuff man thanks everyone for your help!!

Ok so now it's getting plenty of fuel but still is acting starved, weird question, could it be the alternator? I have no idea how old it is and I know it would make it do weird shit if it was going out... Thanks everyone!!

I'd look at the fuel tank switch, mine was bad when I bought my boat...A hole I bought it from knew it and didn't say anything, let me get stuck out on the water 1st trip out. $30 part


It made it act like not getting fuel??

So we are going to try and replace fuel pump and water fuel separator tmrw morning as long as I can find them here in Parker, if u guys have any suggestions I'd greatly appreciate it!! It's so crazy, ran perfect at puddingstone 4 days ago, literally all I did is put new battery and top one tank off at Parker today??? Someone telling me it may be the dual tank switch? To bypass it?
