The XR drive is good drive but the BT even with stock power is just to heavy of a boat for the XR to hold up.

Let me help you here John.... :toetap05:
Bobby, The gear set in the upper is considerably larger, john would have to provide exact specs, and the vertical shaft is also larger. Now I do know that John is working on a new lower that will be stronger.
Why hasnt anyone went with the bravo arneson upgrade kit?????? Going with it this winter. I know the gear size has something to do with it but i think the oil temp has alot to do with it to. Our boats are so much heavier then everyone elses. It doesnt have to say Mercury on it for it to work............. Rik probably will agree

850 Hp and is a direct swap, yes they are in production and will be out in Dec, all the parts are avilable now. Becareful of used Bmax's because there hasn't been any parts for some time available in the market place so most have used old parts in them. Also becareful of rebuilt ones, if you don't know who rebuilt it and with what parts also. Call me for the pricing of new units.

This is one of the most ignorant things I've heard. I hope you are aware that the propellers on the Merc drives are just as exposed they are on the Arnesons. Granted, no matter what drive is on the boat I do not want to fall on it and yes we have a propeller guard for the Arnesons just for the reason of these fearful comments.

I have to agree that was one of the things that stoped me from going with the arneson drive on my BT we use the rear of our boat for getting in and out of the boat when we are coved out and it just makes it to hazardous with the props sticking out there. I understand they make a guard for the top of the prop but when you are in the water getting in the boat you are exposed to the bottom of the prop. Also I can't tell you how many people have slipped off the back swim deck of the BT it is at just enough angle it will take your feet out from under you and you will be in the lake that quick.
Here is a pic of what you are talking with the arneson sticking out behind the boat. We also have trips on ours so it would be even worse. The Bravo drive is 28 inch's off the back of the boat and if my memory serves me correct Rik told me his drive is 52 inch's off the back of the boat.

The Bravo's are closer to 34-36" without a box and on a box are within 4" the length of the Arneson Kits.
The bottom of all propellers are exposed so once again I do not see how the drive being made by Merc will make the pain feel any better and the photo you posted was before I made the guards...

I went and measured mine before I posted so unless 28 on the tape means something else please fill me in on the change.
Lets see swim up between to 2 props that are maybe 20" apart and a then over the tie bar and up the ladder oh there is no ladder on that boat.
Don't get me wrong I think the Arneson is a great drive but I don't think its place is on the family boat. We use the back of our boat way to much to have Arneson's on it and the grand kids playing around them would make me nervous for sure. If I had go fast boat they would be at the top of my list.
