Help Noob Determine Interceptor Engine Size

Tim D wrote: Did you figure out which engine you have? The casting number will give you the year. Just because the boat is a 68 doesn't mean it has a 68 engine. A lot back then had blocks and heads from the year before. My 66 Mustang had a 65 block and 64 heads. How many bolts are on the bell housing? The casting numbers will end like C8 which is 68, C7 is 67 etc.

Tim D, I'm pretty sure we figured it out. Not necessarily the year perhaps, but the size which is what I needed to narrow down parts and part numbers and stuff.

Keno, here's some pics of the carburetor. There is a tough-to-read stamp on one side. It's a circle with the number 120 inside and maybe some small writing around the inner circumference of the circle. Hope that's enough!

Looks like an Autolite 2100 to me.

That tag screwed to the right front of the fuel bowl cover will have the info you need for parts, rebuild kit etc.

I think that was the original equipment marine carburetor on your engine back then although it probably didn't have all the features that a later marine carburetor does.

Rebuild parts or a kit are available and they're a very dependable carburetor.

I've been working on my typing    It worked but I needed more power so I put on the 4bbl! A little nervous about the overflow but I never had any trouble with it. I did notice that with the Holley that it did start easier.

You know guys, the dumb thing is I saw that tag (Obviously, it's sitting right there!) but the grease was so heavy on it I thought it was the patina of the metal and nothing was written on it anymore.   Hahaha. You're right of course, it's an autolite.



So, in addition to that master list of all the advice you two and everyone else gave me, I just need the info from that tag and NAPA should be able to sleuth down the correct rebuild kit? Out of curiosity, how hard is it to rebuild a carburetor? Is it even necessary? Can it simply be cleaned? I want this thing ready to rock so I'm willing to dive into whatever you tell me to as long as you believe I'm not getting in over my head.

Last question, when it needs a new battery, do I get a marine battery?

You need a starting battery does not need to be marine avoid any type of deep cycle. That carb is real simple would not hurt to open it up to see if there is any crud in it and to do that you need a bowel gasket. Might as well get a kit because the accelerator pump will most likely be dried out too.

Wow Gary

We're in sync today, my reply was longer and I type just as slow as you so I must have started typing first

But again, we agree

I don't even try it on the phone unless I really have no other choice

You're good

Yea you never really told us what it actually is

Oh no, oh no, I hope this isn't a 1st gen ski that someone put a tower on.! Oh gee,z that might kill me

Oh gee,z that might kill me David, I sure agree with Steve and am even wondering if you should post a picture of a classic with a tower. Steve, In David's first pictures, you can see side pockets so it may be a Cuda or Stang?

Well, since it wasn't me who (possibly) mutilated it, I can't take any blame so lay down your stones, check it out, and opine

At some point, a fabricated steel tow cage was installed over the windshield area. I'll take a pic of it soon and post it. I love this boat. It sits so low in the water and sounds killer on the water! By the way, is the carburetor indeed the 2100?

Indeed it is an Autolite 2100

Oops double post, I was too distracted thinking about Pete and Skutsch simultaneously having "the big one" when they saw the pictures.

It your boat, do what you want with it and enjoy it.

Pete is seeing red so bad he thinks a Mustang is a 'Cuda

That's a Doozy, lol.
Not sure if you have ever pulled a wakeboarder with your boat yet, if not be aware that if you have a big guy back there and he takes a hard pull from wide out that tiny hull is about going to end up on it's side and you will really need to drive that thing to keep it going where you were previously aimed.
Brave of you to post those pics though, great job!!

How are the stringers? That would be my concern before you go after the cosmetics. Do you know when the last time an engine/prop shaft/strut alignment was done?

Yours is a Mustang somewhat different from a Cuda
Here is a Cuda-



And a gratuitous picture of my Mustang-



Cuda is a bit longer and wider but the big tell tail sign is smooth hull under the gunnel. A Mustang like yours and mine has the molded in "flash" right under it's gunnel.
