Surging and Detonation

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?

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.

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.

No RTV! And what is going on at the carb inlet? Orange rtv?

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.

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

Are gaskets a NAPA item or a SKIDIM item?

Kevin, I think you could narrow the suggestions on this topic as carb or ignition issue.

The carb cost 60 plus labour
the ignition 500 plus labour

I can recall now another expense being suggested, rather than if it's not the ignition it will need changed sooner or later

If any bolt on the carb is leaking, it will need retightening at least, but a rebuild is still recommended
If there's a vacuum leak at the carb base, first you'd try retorquing the nuts at the base I dont think you described an erratic idle so I doubt a vacuum leak is the issue.

The base gaskets, unless very warped for overtightening, can be reused. the sealeant is truth it doesnt belong there.

Bottom line is you need to go and start wrenching, discussing it here wont solve it.

Gotcha! The idle has not been erratic or "hunting" from what I can tell.

Rebuild of the carb is duly noted and kit will be ordered ASAP. It just bugs me that PO says carb was rebuilt 2-3 years ago and it needs to be done again. RTV suggests that it probably was not done correctly!

That's very true! I plan on using it 2-3 days/week every week in summer before lay up in the winter.

Thanks for the heads up on what I need to order. Can this be a local purchase through auto parts store or is it an online purchase?

It looks like the leads going to your choke are pretty dirty. I'd clean then and make sure your choke is pulling off when its warmed up. your describing he noise as pinging. I know ringing as a Sharp metallic knock that sounds like its coming from the center of the engine. Usually caused from overly advanced timing under load. is this what your hearing or is the noise coming from the throat of the carb, more like backfiring. This is usually caused from a lean condition under load and would go along with those super clean plugs. May want to pin down the symptoms while your out. By going with the history and what your describing and the plugs it looks like you may have kicked up some feud in the float bowl that has now clogged a main jet on the clean plug side. I'm interested to hear how this turns out.

is that a normal place to plug the clear line from the fuel pump to the carb? normally don´t the go to the flame arrestor?

I've seen them both


Kap, are you going on saturday to the Axis demo "Choripan night"????

Kevin, your e-mail is private. Shoot me one; I think I have some 351 gaskets from my old boat. I won't need them again, so...

I got this old guy who irratates the fck out of me, new boat nice car and always picks my brain about his boat problems, hasnt spent a dime yet, man, do i send him off in the wrong direction...lol, he just one of those guys. really though, for some reason its the only guy i will do this too and hope it isnt taken the wrong way

I'm not sure how I should take this, but I'll try. I'm thinking you mean crap, or get off the pot?

If so, know that I am working on correcting the carb leaking issues and the leaking vacuum that you had mentioned. Hopefully it will be done this weekend and I will post results.
