Update: They came in today.. good looking, and for the hell of it I put them under a microscope to look at the edges.. nice and sharp, no fraying @ 100 power. Can't wait for the gaskets to arrive so I can put these bad boys in. :sly:

OK... Update time.. Carbs are rebuilt and the gaskets finally came in.. (First set got lost in the mails). Everything is ready to install today.. will update with pics later as the job progresses... Who knows.. maybe I'll have a (working) boat by tomorrow. :head:

Plastic carbs, W.T.H. I hope you get it going. I guess they did that to save some money maybe? I just don’t understand why they think that would last. I have never been a fan of using plastic parts on a motor but now days everyone is doing it. Look at a new Jeep motor the 3.7 v6 it has a plastic intake manifold.

OK ... mystery solved. Recall that I origionally said that the engine was a 200 hp as per what I was told from the PO. But it was pointed out to me that the carbs were 225's, based on the pics of the butterfly plates clearly showing 3 screws in each butterfly. I thought nothing more of it until today as I was getting ready to install the carbs back onto the engine when I noticed that the 3 good carbs from the old, melted carb set looked like they had a smaller venturi than the 3 new 225 replacement carbs that I was installing. I did some measuring and found that I was right. So what I actually had from the PO was an engine with the 3 screw butterflys of a 225, but the plastic bodies of a 200 mounted onto them.

So here's my questions? What should I be running? Understand, I have a complete set of 200 carbs with 200 (2 screw) butterflys, and a complete set of 225 carbs with 225 (3 screw) butterflys. I know that the 200 should give me better MPG...will I see any great performance difference if I use the 200's instead of the 225's? My thoughts are that if it's ok to do, I'd like to use the 3 screw butterflys. That way I can use either the 200 or the 225 carb bodies, depending on how I want to set up the engine.

Ferm, Spare and Skools... I think this is in your ballparks. I would be greatful for any suggestions or opinions.:head:

I think Skools is the expert on this subject, but I don't think you'll notice enough difference in fuel usage between the two. I'd go ahead and run the 225 set up. After you get it dialed in, see what your top rpms are, you may be able to reprop due to the added power(between the reeds and the carbs) and add your cruise effeciancy

Go with the 225 carbs as they WILL get you better economy. The 200's will give better throttle response, but don't get as good of milage. Just make sure they are actually 225 mid bores as there are about 4 or 5 different venturi sizes for the plastic carbs. The V-6's used 2 main sizes of carbs, the 200 small bore and 225 mid bores. There was also the infamous 200's early on that came on the 200GT's that were MONSTERS of carbs, but they are not good for much but WOT. Then there are the V-4 carbs which there were some that were almost identical to the V-6 ones, but would be a 1/16 or so smaller or larger than the 225's. vSO make sure all of the venturi's are the same size. And don't mix and match baseplates as the yare calibrated for the carb bodies for air bypass and jetting for idle and mid pull-offs.

Thank you both gentlemen, that's exactly what I was looking to know. :beer::beer::beer::beer::beer:
