Baller Jaypro Posted July 8 Baller Share Posted July 8 Hey Ballers, I was hoping you might be able to give me an idea as to what might be giving my boat hesitation out of the hole. If I give it full throttle, it sort of sputters and hesitates until it gets to plane. feels like 1/2 power? If I give it a progressive throttle it hesitates much less. It has the 330 Excalibur motor. I changed the fuel filter and ran some seafoam through it, but it is still there. Any thoughts? Is there a fuel line filter I am missing, any other thoughts?

Baller BKistler Posted July 8 Baller Share Posted July 8 There are two fuel filters on that engine. The large canister and a smaller filter that has a mesh basket. My small filter is a pain to service. Even with clean filters, I sometimes get a vapor lock hesitation after the engine is hot and is turned off for a while. It’s only momentary and returns to normal operation right away. 1 Link to comment Share on other sites More sharing options...
Baller jpwhit Posted July 8 Baller Share Posted July 8 How long has it been since the distributor cap and rotor have been changed? If not within the last 300 hours, start with that. Very common area that causes issues on the 5.7L GM engines if neglected. 7 Link to comment Share on other sites More sharing options...
Baller rawly Posted July 8 Baller Share Posted July 8 Mine is a 2009 model. The second filter is under the floor behind the engine. Link to comment Share on other sites More sharing options...

Baller Andre Posted July 8 Baller Share Posted July 8 Triple what jpwhit said. But for all those hesitation problems,putting a gauge on fuel pressure is a good thing to do. 2 My ski finish in 16.95 but my ass is out of tolerance! Link to comment Share on other sites More sharing options...
Baller igkya Posted July 8 Baller Share Posted July 8 As others have stated, but check the D-cap/rotor first as it's the quickest and easiest, then check low pressure fuel filter, which is sometimes a PITA to do. 2 Link to comment Share on other sites More sharing options...
Baller BlueSki Posted July 8 Baller Share Posted July 8 I found that changing both filters annually make the FCC filter much easier to do than those that have not been changed. It is still a PITA to drain the fuel from the canister, but the pain is less. Link to comment Share on other sites More sharing options...
Baller buoyboy1 Posted July 8 Baller Share Posted July 8 Agree with others. Change cap and rotor. I had one or the other go bad after only 70 hrs. My symptoms were identical to what you described on my 05 196. 2 Link to comment Share on other sites More sharing options...
Baller_ Wish Posted July 9 Baller_ Share Posted July 9 Following ..same with my GT40 and it seems to be intermittent. Can have an entire set no issues. But does seem to follow the “does it more when warm” 2nd or 3rd set with little down time. Link to comment Share on other sites More sharing options...
