Bahahaha that’s some funny sh!t...You must be self made then!!! hahaha

:lolhit:

Bravo! It's settled then, let's go boating. I hear winter is over....

On benefit to going with the SCX, if you find that later on the -4's are the required solution, you are not going to take a beating on selling the SCX as they are the go-to upgrade that everyone is after..

How many Merc drives has your Cig gone through or was that not disclosed when you bought it? SCX will be remarkably better suited to the bigger boat/HP with minimal dial in for the new set-up. My $0.02.

Not sure how many drives it's gone through. I finally go it out yesterday. The 600 were modified, but done in Italy, and nobody knows what was done for the increase in power. I was getting 10 lbs of boost, and I think a stock 700 is 7-8 psi isn't it?

The boat came with 32 bravos, but I was told they hit the limiter, so I bought 34s, and that is what I ran yesterday. Even with the 34s Bravos I'm on the limiters a little past half throttle. I was able to hit 94 mph. I'm running out of bigger sizes to go to, maybe a 36 would be enough? As it is, I'm at 18% slip.

I talked to Offshore Cowboy, and he swore by the custom 6 blades he had Throttle Up build for him. I may have to try a 32 six blade Herrings. His boat had 600's and Bravo, he said he never had an issue with his drives, but he was also running stock 600s. Matt told him the 6 blades were better on the drives than a 4 or 5 blade. It doesn't make sense to me that a 6 blade would be easier on the drive, but I'm also not a prop engineer.

Either way, I agree with the SCX. If at some point I find out the -4s are the better set up, it's an easy switch. The boat feels really good as it is, I just need a better upper.

Did you run her on Portage yesterday?

I did, and then ran up to Arcadia and back. It needs different props, but I really like the boat. It was fun to finally get it out on the water!

OP, I never did say to do a M6. I was just correcting the fact that 700 w/ M6 is a full stagger. I'd agree Imco would be the way to go. Carry on ----->

Is this the one that says 600sci on the sides that was recently listed?

Mine was listed for a while, maybe last fall? Not sure exactly when it was listed. As to the 600 on the side, are you referring to on the sides of the superchargers? If so, yes they are 600 SCIs that from the outside appear stock.

I think he is thinking the 600th Gun. I think it is 575sci's

Anyone know of the straight bottom with the scx4s I’m interested in how high the drives are. I’m In the process of doing scx with #6 props or scx4 with #6 props. With the scx4 I can run a 17.5 “ prop and 16.5s on the scx. My boats on a its and no notch. Just worried about having planing issues with the scx4s.

A lot of info on here about that. Even with the bottom and you will have planning issues, and would need a minimum 17.5" or 18" diameter prop.

Shoot for 1-1.5" below and still plan to use a 17.5" diameter prop. Do you have boxes? where you can adjust up and down? Can you space the SCX4 down? Then you could start at even with bottom and go down if needed and when you find what the boat likes.

im on a its and im about 4" below now with std height xrs, the bullet is 16" back from transom, you can space the scx4 down with spacers in 1/2" increments

thats where my prop shaft is, ITS has a 7.5" set back.....I just picked up a pair of IMCO lowers going give them a try

yea 7.5" setback plus the drive puts me at 16" back from transom, id be at 2 - 2.5" deep with a scx lower, just wondering if thats still too deep with the #6 cleaver at 16.5" diameter

gets expensive chasing a few mph......Ive heard that boats have lost speed going from an XR and SC lower to the SCX, but no doubt stronger, the SCX 4 is a true surface drive

We just installed SCX's on my buddys 38TG TS. It had XR's with standard Bravo lowers(not sport masters). We used Teague blueprinted standard height SC lowers and it only seems to have lost 2mph.

ive heard the new scx lower isint as bad as the old one, im on the fence with the between the scx and scx4, power will be 1000hp so either should be ok on my old resin bucket lol

you have a post on FB about this ? saw one similar

yes i know theres a straight bottom with scx4s floating arroun, just wondering what the height and manners of the boat are

It is funny you should being that boat up. I had Marc Jacobs transport my boat from Miami to Alabama, at which point I trailered it the rest of the way to Michigan. Marc was picking up the very boat you are probably referring too. It is a straight bottom gun, with the 90 MPH red and white paint, and SCX-4 drives. I don't remember if the boat had boxes or not. I chatted with the owner as he was there as well. He told me the handling was worlds better, but he lost I think 10 mph over the standard Bravo package he was originally running. I don't remember the before and after speeds. Personally I think SCX-4s are to high for a straight bottom gun. That is probably why he lost speed, I think he would have been better with SCX. Give Marc a call, last I knew he was brokering the boat.

I'm still seriously considering SCX-4s on my boat. The NXTs are 1" shorter than my current set up and worse case, I can space down an inch. Have a guy interested in my SCX that I bought this summer, if he buys it today, I'm going -4's.

My thoughts are if I go scx4 I can space back down to a -2 that the scx is. If I go scx I’m stuck with -2 that it is. I think that boat also had a eared prop not a surface cleaver

Does the minus 4 allow for spacers? I didnt think it did

yes you can space up to 2"

After months of trying to decide SCX or SCX-4s I finally pulled the trigger and the new drives were ordered. Recently "Spicy" was put up for sale, and it was running SCX drives. I talked with the owner and he was very happy with the performance of the boat, With Whippled 525s he was seeing 100 mph with stock 32 Maximus props, 103 with Herings. I recently talked with Tres Martin, and he recommended the SCX over the SCX-4 but to stick with the sport master lower. Then there was the 39 with 700 Zuls (Fire Escape) with SCX-4s with Hering cleavers, it had a Max speed of 103 mph.

So with all that said I went with SCX uppers and the the 1300 lowers. No I didn't go with the twin downshift lower. I'm not a huge fan of that lower as you can only use a 1.25" prop shaft. I have the 1 7/16 prop shaft so I can run both Bravo and cleaver props with the adaptors.

It will be a fun spring when it gets here. The engines are getting fresh top ends as well as new cams. When I bought the boat I was told the engines had been converted to 700 SCIs. All that was done is someone put a 700 tune in the 600 ecu. All summer I was replacing sensors trying to keep the alarms from going off. When I realized the engines still had the 600 cams in them, I called Mark Boos, and he said, "that's your problem, the MAP readings would be off with that cam". So finally I will be able to use the stage 2 program Mark installed last July.

96-97 was my best speed run last year. It will be interesting to see where I end up. I'll keep everyone posted when I get some results in the spring.
