Not a Correct Craft but cool/fast.

Customer brought in his newest aquisition so we can cut holes and put a nautique FCT3 tower on it.

The second of two Malivettes the family owns. You can guess what water sport they like to do.

Confirmed 57mph on Gps. It looks new and still sports the original Vette goodyear tires.

What is the wake like at 70 feet? I have never heard of it being any good. The only reason to have a fast barefoot boat is for wake slalom so fast is only good if there is a nice wake to cross.

Is that the same hull as a Sportster? Those have nice footin wakes.

Lets see the tower on the wolf pack boat there and the folding tongue. Or I'll just see it myself Saturday.

Curious to see what the Corvette looks like with the tower mounted on it as well.

We may be changing their mind about that FCT3 on the Bu. We are going to have to take out a ton of metal from the center section to make it fit properly. It will probably end up looking goofy.

I would assume it's the Calloway motor Riley. It has the Big throttle body deal on the top of a single plane intake. It also has Hi Po manifolds with a iron lower section and stainless risers. It clearly makes some power to run that fast.

I believe the Vette was based on the Echelon, which was their flagship boat before the Response. I think the 1st year or 2, the Response had the same hull as the Echelon which was the same as the Sportster, but later had improvements that made it better for slalom, but not as good for barefooting.

From some quick searches on the WWW....
Tim is correct on the Callaway 383 Suoernatural. It was built by Callaway and marinized by Indmar. It was based on the 350ci LT1 engine which was iron block and aluminum head. The LT1 engine was designed to be reverse cooled from heads to the block. The inherent cooler temps from the aluminum head as well as the reverse cooling allowed compression ratios to increase.

Indmar rebadged the base LT1 into the Hammerhead and maybe a couple others (Monsoon or Scorpion???). The early LT1 based engines did have some issues. I've heard it was different expansion rates of the heads/block or maybe it was the reverse cooling or a combination of both????? Who knows.

I'm pretty sure any early issues with the LT1 based engines has been fixed.

There was a guy on MalibuCrew, Galaxytoad, a few years ago that had a Sportster with a Calloway Supernatural and he had a lot of problems with it and ended up rebuilding the engine. He claimed he got 60 mph out of his Sporster with 4 people sitting in the back seat after the rebuild.

Malibu's 1st Hammerhead was a 5.7 with aluminum heads. According to members on TMC they started having problems supposedly after Indmar had to switch to a new head source. Indmar then came out with the new Hammerhead which was based on the 383 and was 400 hp and eventually 425 hp. I remember people posting that those engines were using oil, but I they ran well.

The Monsoon was a 5.7 with efi and was their flagship motor for a long time. It might still be. I believe those were a crate GM motor with Indmar efi.

Indmar did some cool stuff with engines like the Hammerheads and they also had a Corvette engine. It was a $5k upgrade when we got our Sportster and weighed 200 lbs less than a 5.7. Someone told me they were prone to burning valves if you ran them hard, which I found surprising seeing it was a late model hi tech Corvette engine. I would have thought they were meant to be run hard.

You could be correct Tim about the Callaway being an issue but I know I've heard of issues with some early aluminum head/iron block engines. I just don't remember for sure what they were.
I have a buddy who has had several Barefoot BU's with the Hammerhead. He always traded up every two years. I keep thinking his first Hammerhead was 377ci. and the next one went to 383 and I believe his latest one is a 388. I skied behind three of them and all three were very fast. He never had problems that I'm aware of but he didn't put more than a couple hundred hours on each one either. He said he knew of others that did have problems though.

Riley, I know a Sportster with a Monsoon engine is pretty friggin' fast. I think my dream boat would be a Sportster with a Hammerhead. I know my buddy with the Barefooter Response LXI and a Hammerhead does well over 50. The LXI tips the scales at almost 2900 lbs. I gotta believe a much lighter weight Sportster with that same Hammerhead would be a rocket. It would not surprise me at all to hear somebody doing 60+ with a Sportster.

Finished the install yesterday. Some custom welding and paint work later it turned out looking pretty dang good. It's a little tall IMHO but I prefer the 2 point mount towers as opposed to 4 point. Satin black goes with the boat well.

Pulling it down today to have the cover modified.
