1" shorter drives on a 36 Outlaw
 

Is anybody running a 1" shorter drive on a 36 Outlaw ?? Now that it is the end of my season I want to change to shorties but I would like to hear of some success stories before I change anything. I do not have stock power, so please also tell me what you have for horsepower as well.


Thanks--

Smitty

Since you aren't getting any replies I'll tell you what little I know.

Have a friend that built up a 36 outlaw. It was a 2001 model with 502's. They made 509's and Whipple charged them (850 HP). I thought he had 2 inch shorties on it and have posted that before, but I was wrong. They were 1 inch shorties, IMCO Extremes.

The boat ran very well (92 GPS) and handled well. He was pleased with it, but it did not run triple digits and he bought a cat.

There was a thread not long ago where a guy tried 2 inch shorties and could not get on plane.

Personally I would add extension boxes with the shorties. I think that is the way to go with these boats from what I have learned.

Hope this helps a little.

THEY DID NOT WORK ON MY 99 36 IT WAS REALLY HARD TO GET ON PLANE AND SLOWED THE BOAT DOWN BAJA DID PLAY
WITH THE X ON THE 99 AND SOME 2000 MINE IS ALREADY
UP 1.5 INCHES SO WHEN I PUT THE SHORTIES ON IT WAS TO HIGH I HAVE 509'S WITH 610 HP GOOD LUCK
I DID TRY THE 2 INCH SHORTIE.

Re: 1" shorter drives on a 36 Outlaw
 

Thanks guys !! I have 750 hp per motor and I am going with the 1" shorter drives. I would do boxes too but not in the budget right now. I hear that I can see about 3 mph gain so that will get me to around 86-87 and I would be happy with that. These boats are heavy and not efficient so I know if I want to see over 90 I might as well buy something else.

Thanks,

Hey Smitty What Props Are You Using?

Re: 1" shorter drives on a 36 Outlaw
 

I currently have 1.36 ratio drives and I am running 28" stock Bravo 1's When I switch drives I will go 1.50 ratio and use at least 30" Bravo 1's

Smitty,

I have a 99 36 Outlaw with 2 1/2 inch shorter Imco Extreme SC's.I bought my boat late in the summer of 98 as a 99 model. As far as I know Baja had not changed the X at that time. I agree with Dock Holiday, you really need extension boxes. I have 8" set backs (not a stand off box on the transom but a Land & Sea box that attaches to the Gimbel and pushes the drive 8" back). I put the boxes on prior to raising the X. The 8" increased my top end by 4 mph by it self. When I raised the X 2 1/2 " I had lab finished 4-blade Bravo's. The boat got on plane and ran but the props were really slipping. I only saw about 84 mph. I bought a pair of Herring 6-blades and the boat came to life. For the past two years I have been running 94 to 95 mph in good water. If it is flat I still can run 92. I have 750 hp motors and boat in Lake Huron. You really need the boxes to get clean water and then you need the 5 or 6 blades to carry the boat with the higher X. If you can't do the boxes now just know there is more speed left in your boat if you want to spend the money.

Re: 1" shorter drives on a 36 Outlaw
 

When you added the land and sea exstensions whar did you do for your hydraulic steering rams? My 272 runs just over 90mph with a stock length drive at max trim and I think there is some more speed there if I add the land and sea exstention but didn't know what you did for steering rams,the other Smitty

Re: 1" shorter drives on a 36 Outlaw
 

I added the extensions about four years ago so I don't remember exactly what we had to do. I can tell you we used the same rams that were on the boat but they were attached at a different point on the drive. If I recall correctly I had to have Lathem custom build a new top plate for the drive to allow the steering to be re-attached. Land & Sea told us what we needed to do. I know it worked fine when Lathem was done. It wasn't cheap but it worked and looked great.

WOW a 90+ with 750hp in a 36 that is impressive. There is hope for me then, I want a triple digit 35 or 36 but it might have to wait for another 10 yrs.

Re: 1" shorter drives on a 36 Outlaw
 

Drill IT,

Thanks for the information. You have an AWESOME setup there buddy.

Would you PLEASE post a picture of the transom with the set backs so we can see how the look.

Thanks

2005 36 outlaw deckolite with 2" shorties ITS, power is 575 chillers 625-640hp , i'm running 32 lab 5 blades absolutely no problem getting on plane, amazing mid-range with a top speed of 86mph. Have seen 88 in 2 foot chops.

Re: 1" shorter drives on a 36 Outlaw
 

Gatcat,

Do you have a 35 or 36 Outlaw? Did they already make a 35 for 2005? I am just curious as I haven't seen anything on a 35.

As far as your speed that is impressive also. What is the weight of your boat?

Thanks!

Re: 1" shorter drives on a 36 Outlaw
 

Gatcat,

Forgot to ask, do the ITS drives have a built in set back? isn't it 7"? You mentioned you are running 5-blade 32's, your boat must be light on the water. I am running the Herring 6-blades but they are only a 28 pitch with 1.5 gears.

Thanks!

Dock Holiday,

I would be happy to. It will take me a few days but I will try to get a picture and post it by next week. I appreciate your interest. We all spend a lot of time trying to make these Baja's run and it's nice to be on a site where everyone appreciates and is interested in what each other is doing.

Re: 1" shorter drives on a 36 Outlaw
 

Has to be a 2005 36 there is only one 35 hull that I know of so far and it didn't even have the deck on it yet and that was about 2 weeks ago.

If however I am wrong I would love to see that boat and that setup.

Re: 1" shorter drives on a 36 Outlaw
 

My boat has stellings boxes with latham
steering.
It has a plate on top of the drive that
has the mounting for the steering ram
yokes off to the side of the drive( as
opposed in the rear cap)

The steering cylinders appear to be the
same as those without boxes, that connect
up to the rear cap.

This setup may work for you..

Something else,
When IMCO was building their version of
the stern jack, they attached the rams
to the side of the drive extension,
( actually, their extension had the mounts
built into the extension)

I would imagine you could
attach a mount to the side of the
land and sea extension, and keep
the same length steering rams.

Drill it,
I really dont now about the set back but the boat is not light on the water i would even say i find it heavy, as for weight they say (dealer) that it's about 800lbs pounds lighter than a 36 standard. The big difference is how the boat is solid in rough water because of the carbonfiber stringers.

Re: 1" shorter drives on a 36 Outlaw
 

Gatcat,

Did you ever run standard lowers with
4 blades ?

If so, what size were the props and how did it perform ?

Re: 1" shorter drives on a 36 Outlaw
 

Sorry it took so,long to get back to you i was gone moose hunting, i did not try standard lowers but i did try 4 blades and it did not work,cause the X not done by the factory we did it very high and the 4 blade slip and we lost rpm and speed :evilb:

Re: 1" shorter drives on a 36 Outlaw
 

Sound kind of like mine.

I have stellings boxes, prop shafts are about
3" below the bottom of the boat.

I usually run 32 bravo's, on a good day,
I'm against the rev limiter.

3600 rpm's ='s about 52 mph.

Have to baby it out of the hole.

Tried a set of 32 maximus 5 blades,
came right out of the hole, no blow out. :D

3600 rpm ='s 62 mph. :D

Would only turn up to 4800 rpm on top.

Top speed was about the same..

I'm pretty convinced that these 5 blades could be
ran up higher, but don't know if the rpm's will
come up enough, may have to go to 30's

I think the 5 blades and the 2" shorties
would be worth a couple mph up top.

Now, just need to find a set of shorties.

Dock, How is my buddy Kieth doing anyways ?? Do you have a number for him. If so pm it to me or give him mine. I havent talked with him in along time. I lost his number with my old phone

Keith is doing good. He is a super nice guy.

He is loving those triple digit speeds!!! :D

I sent you a PM with his phone number.

Take care

Re: 1" shorter drives on a 36 Outlaw
 

I need some advice. I have a 87 320 that I raised the x on 3" I'm running 4 blade bravo's 24 pitch, I get on plane fine and the boat runs ok but I fell like I'm lacking in speed. It seems as if I'm not hooking up at WOT.

Would a set of Imco nuetral boxes help get clean water to the props to get the boat to hookup better and get some of the speed back? Or should I notch the transom 8 to 10" to get the clean water back to the props?

Any thoughts would be greatly appriciated!!!
