Downside- a giant exposed prop on a hydrauliclly actuated arm can kill towables, or skiing - the rooster tail is on par with a jet-o-vated equipped berkely on 5/8 UP - and can be considered dangerous for swimming etc. They make a guard for it, but it is what it is. :ernaehrung004:

The Bravos are right at the surface to. Remember the propeller shaft is only 2-3" below the keel and thus the upper half of the propeller is out of the water.

We have a propeller guard that offers more protection than a Bravo or Speed Master does.

I have a few boats that ski behind them and it does not hinder them.

You guys are way out of my league for now. Any chance you want to sell the XR's to a struggling new and up comer? Please email me at [email protected] Thanks!

Yes, Max Machine is building the upper for me, but I am keeping the Imco shorties. I think my mechanic took the XR drives to Max in Lake Havasu and they should be back in 10-15 day's as the new uppers are ready. If you are interested let me know and we could make a deal

XR Upgrade
 
Mike wrote:
There is nothing wrong with the drives at all. Got them last summer, as i updated my bravo 1 to XR drives, when i updated the motors. But now i just purchased big motors and need to upgrade once again. We were going to upgrade the XR's, but decided to get all the new drives. I will let you know in about a week or so on what they are planning to do.:boat:

sure it will man theres a few BAJAS out there with big power doing fine and fast in the 90 to 100 mph class. that 33 is not a lite boat and handles fine in rough water. AND I HAVE BEEN IN THE ATs the new 33 blows away the older boats two diff animals, a lot to do with set up and step. baja 33 you could look at a konrad to even thought they are rated at a lower hp I know of a few with what you have and run fine. also MR. GADGETS OR MARINE TRANS could up grade your drives. or the surface drives rik makes arneson you would have some cool rooster tails with those :D if not just take it easy getting on plane and getting air you can't miss it.

thats why they sell ski ropes at 120ft or longer:D your not in the rooster, plus I found it to be better sking behind my bravo boat with a 120 or 150ft rope than a standard 75ft rope cleaner water and ocean racing uses 200 ft I think.
