Direct drive ski boat on roller trailer?

[scottybm1]

I just purchased a nearly mint 1997 Moomba Boomerang but the trailer is rusted and unsafe to use. Looking locally I've found a couple of roller type trailers that are taller and narrower (which is good) but I'm concerned about using a different type of trailer than the original. Any thoughts?

Never seen one on a roller.
The big concerns for me would be:
1) Tracking fins getting caught up in the rollers while loading if you got crooked - as well as tracking fin clearance to the frame members
2) Rollers tend to be built for rear engine boats, the weight in your Moomba is all in the middle
3) lack of a prop box at the rear of the trailer and clearance for the shaft and the rear crossmember.
