I made a new rudder housing that accepts a "Bravo" style propeller.

The Maximus will fit also and this propeller has 30 degrees of rake. This will allow a smaller boat that does not/can not handle a Cleaver propeller to run an Arneson without being burdened by a cleaver propeller. The drive will have: Less Stern Lift Less Side Loading Reduced Listing Lower, FAR lower propeller cost and sourcing Less "Man Handling" from the propeller More Bow Lift Less RPM to get on plane Wider selection of propellers Lighter propeller (if that matters) Improved reversing, as the blade is not so blunt in the rear Better tracking More Propeller Rake. 25-30 degrees vs 15 for a Mercury Speedmaster. For a small, or single engine application, this was an issue to some degree depending upon who's hull was being used. The propeller cost and selection was always an issue. Now with the high rake Maximus, the Bravo and others the advancement of technology has allowed us to take advantage of it. It's looks like you may have a winner here. Can we get more specs. Plus a picture? Also, is it compatable the original Bravo cutout? |
Rik,
Does it still use a trans? Please show and tell. I'm on the fence |
Spoke with Rik today, it does sound as if he has the Bulletproof answer to the XR with big HP. :grinser010:
|
Does it bolt up using th e existing holes of the XR?
|
It's based on my same "Bravo Conversion Kit" so the cutout is not an issue as my standoff box covers the Bravo cutout.
Yes it uses a transmission, BAM so there is no problems with a cone clutch. No weak links. I'll have photos in a week or so when I get it on a boat. |

I should spend a few hours and draw something up on Autocad that bolts up to an existing Bravo, and patent it! Like an ITS with a dropdown in the rear to accomodate a dropdown box, around 6". Connecting to a surface drive! I'm a friggin genious!!! Why hasn't Arnesson thought of this? Just send me the royalties ;) I'll give you 3 weeks till I draw it up. Then it's all mine,and you'll have to buy it. Just kidding. Make it happen!!! It should have been made years ago! You guys would be beyound rich!!! Rick |

Rik, Did we already go through this before? Or does this unit bolt to the "existing" bolt holes of the XR? Or does it use a Bravo hole pattern?

You guys would be beyound rich!!! Rick That was an old thought. Problem is you would need a different one for every boat out there as we all know some boats like an X here, some like and X there, some like an X everywhere. On some boats you would be running the drive mounting below the bottom of the boat so it is far best to do it like I am. Just mount our Standoff Box at the advised height for the transom angle (another variable that presents a problem for a fixed design). The box covers the Bravo cut out so there is no glassing concerns, and it is easy to install. Once the box is installed the rest is plug and play. The engine is set by this also. |
Rik, looking forward to seeing some photos and performance data on the new drive set up !!!

Rik
Hi, I also spoke to you when I bult my 30 Y2K. Isn't there an issue since our transom's are notched? |

Where would the prop shaft need to be on a 30ft single to be correct Rik ?

Depends upon how large the notch is. Majority of them need only a slight filler to allow the drive to be mounted at the correct height.

Gary... Merry Christmas http://www.xpowerdrive.com/images/ML286XPower.pdf

Tom, that drive looks like the answer to all XR issues and big hp, time will tell !!!
|
Nice pick Gary !! You must have some really long arms. Or did you use your shoe cam from the bar days. LOL
I like the looks of that drive. A surface mini 6. Drysump with a cooler . NICE What prop shaft does it have ? If it surfaces like its designed to do your going to need at least a prop with the diameter of 17. Been their done that with the small diameter. NO GOOD Gary its going to be a long winter of choices !! |

Gary, thats one impressive drive. Rated @ 1535 HP. With zero failures. 800 HP should be bullet proof. I'm curious how much it costs.
|
925hp HMMMMM, How many cubes is that motor ? Gary you know to raise the compression mite mean new pistons. Probably more than just a head mill. That drive has to run #6 props.
|
Mike, the motor is 605 CI. So the X-Drive is not a direct replacement for the bravo xr ???
|
Potter must be really good . I thought 775-800hp was about the number for 600 inches on 93 octane. Especialy running under 5500 rpm.

|
I think the reason for the magic number of 800 HP is the idle quality for Bravo drives. Consider the relatively small cam in my motor for idle. You can put a monster cam in a 600ci motor and build much more power but idles at approx 12-1500 rpm.
|
I don't care what you all say....... Babi needs that drive. ;) Babi needs to be Happy. ;)
|
With an idle that high Id be treating that drive like a crash box and starting it in gear as much as possible.
|
The Potter 800 idles at 900 rpms
|
Mine idles at 900 also.

So G.
How is she running? Are you whipping up on everyone around your bay? Buy a spare XR and save the rest for gas... |

Thats a bit much dont you think. I heard the new imcos are pretty good. I think their low teens.
|
At 35k there will be a very limited market,probably none they need to price it around 15-18k and get some out there to prove there product.Gary they need to send you one for free and run the crap out of it for 300hrs and see how it holds up,then they need to put a pair on a 36 offshore cat and really put it to the test,only problem is the stock gimbal will probably break and sink the boat,it does look like an awesome piece go ahead and get one
|
Mike, Dave, 35k is steep. I would think for most guys doing a XR upgrade the X-Power may be out of reach. I think the new Arenson is 23-26K. The Imco SCX 13-15k. Teague Plantinum 10-11K. Max-Worx 10-11K. New XR 7-8K. What to do ????:eek:
