Not sure what that is at the inlet. It kind of feels like wax??

Are gaskets a NAPA item or a SKIDIM item?

Yes, new gaskets and some are better than others. You want to do this before going to the lake. Pull the carb off and post a few pics. I'm not the guy for the details you need. Someone who knows will drop by.

Kevin, three pages have gone on this topic... how many more educated opinions are you waiting?

Go for the carb, maybe just remove the front bowl and take a pic, if it looks pristine we might discuss not disassembling it.

I will also take the liberty to give you some advice, if you plan to keep the boat and claim to be on a tight budget, you better start learning how to do the maintenance yourself, and do it right, or you wont be boating very long. Boats are a money pit.

You'll get any instruction you need on this forums, but if you hesitate on a U$D60 carb kit I suggest you go get the car back.

Hope you dont take it wrong, just happen to see a lot of people in your situation (I work with boats) and the boating experience can turn into hell if you count the beenies.

I'd look at mine like it's the money hole that it is and drop the whole G to replace the carb and the ProTec. Lol

Mine will get the ProTec replacement to prevent issues as much as anything, a guy in my crew is having his new Tige Z1 delivered thursday so I've got a weekend boat to use the rest of the year, dropping $20 for gas is much cheaper than running my own these days. I am watching this though because I won a 30% off coupon for a full Wetsounds system and the wife would rather see that idea grow than me fixing maintenance items. I guess that's a good place to though if I think about it for a while.

Look at it this way, if the Protec is bad, it will cost U$D500 plus labour to install the retrofit.

The complete carb kit will be around U$D60 plus labour...

What would you try first?

Sorry! This lower port bolt. I also notice the use of RTV at the base of the manifold/spacer. Is this normal?

Gotcha! I can do that myself. My symptom is consistent. It's more like it randomly (as in once) got up to about 45mph before it started to bog down again. Weird because the week before I took my 3 and 4 year olds tubing for the first time and it ran great with none of the above symptoms!

engine sounds good.
Just normal issues of unused boats..
you will have it sort in no time and will enjoy your boat!![/QUOTE]

Man I hope so!

[/QUOTE] I totally understand the family and vette thing! lol I have 2 kids so its definetely not a family car! I´ve considered streching it and adding 2 more seats or trading it for a camaro or Mopar of that era...but man the vette is nice![/QUOTE]

LOL! Don't get rid of it!! The price of that vette is appreciating like crazy and I don't know that the camaro or Mopar will like the vette will. I know in 10 years I will need some tissue when I look up the NADA value of the vette.

Kevin, no offence lol...

I've been getting a lot more use out of the boat, and family and friends can join in. I think you'll love your boat once you get this sorted. If that fuel sat around since July 4th, I'm guessing it's the source of a lot of your issues. Try adding some Starbrite Startron to your tank, see if that helps matters. Send some detailed pics of your carb if you can. The only thing you can really check easily is the inlet screen, where the line goes into the carb. Make sure you use a flare end (aka line) wrench to undo any brass fittings.

I hear you about not being able to have all the toys! The reason we went to a boat is because My family of 4 cannot fit in a two seater! Plus, my wife and I are both teachers and so we will have lots of family time out on the boat...pending the things runs!

I added some HEET to the tank, but ran the aux. tank yesterday and it still did not want to run right. Either there is something in the carb clogging things up or there is spark issues.

I did check the inlet screen. It had nothing stuck to it at all. I changed the fuel/water separator as well.

I will post some pics of the carb this evening.

Or did you mean me?

Hello! My name is Kevin

Ok, I was just curious if it might have been an accelerator pump issue, it sounds like no on that.

Plugs have a few hrs on them, I pulled them mid summer and they were pretty even. Certainly couldn't hurt though, they have a few hundred hrs and will be replaced anyway with the ProTec. I figure the ProTec is living on borrowed time, with over 900hrs so it's on the winter project list.   I'd rather do on my time than to loose a bunch of water time during the summer.   I've also got a bit of an itch for a little hp upgrade to so I'll probably throw in a cam and and intake while I'm at it and have everything apart.

KV, Is the sputtering happening while you're up on plane and going along, or more as you juice it out of the hole?

I'll chime in because my ProTec seems to be on it's last leg. I have similar hrs and mine has never given me any trouble, but as the summer has gone on I seem to be a little down on the power. This past weekend we put 15 or 20 hrs on the boat at an event where we had the boat fully loaded with people the whole time. It the first time I can remember running out of power to get out of the hole.   The boat was still as quick as all the big 24fters there, but I had nothing left when people asked, most didn't notice though.

My ProTec seems to just be getting weak, no sputtering or other issues. Best speed I could manage unloaded this weekend was 41 with the bimini up and 300 lbs of lead in the bow. Both those things aren't helping and I'm going to give her a run this week without them this week to make sure I'm heading in the right direction.   I didn't notice any increased fuel use, and RPM's stayed within reason of what we usually run which is why I'm suspecting weak spark.

You my have 2 issues both fuel and ignition.
