What is interesting is that with this drive, we have the whole spectrum covered. First we have Trimax which is not trimmable nor steerable. Just a fixed shaft, thus requiring rudders for steering. Then we have the BPM drive which is not steerable and thus requires rudders but is (slightly) trimmable. Then we have Arnesons and the likes of SDS drives which are trimmable and steerable. And finally we have the Sage drive which is trimmable, steerable and with a variable X dimension, in other words it moves all over the place. No prizes for guessing which is the most reliable. Plus, the Trimax can be set at a really shallow angle (2°) because certain design characteristics allow it to keep good handling characteristics even at this angle (cavitation control). So you can be just as fast if not faster than others while keeping it all supremely reliable. It simply NEVER broke in racing and it is fast. Look at Tommy Bahama. As far as I'm concerned, it's really the best surface drive system. I am expecting to be shot down in flames for saying this but I'll leave it at that...

you are obviously not south of Bar, and working for the right side. I am really impressed with your Trimax knowledge.

FWK/ I was refering to 33' Endagered Spieces that was a race boat, that Dennis Bradley later purchased and campaigned as a B boat Tsunami. I had been told the boat had Arnesons originally, barrel rolled and swapped ends a couple times as a race boat and then Dennis purchased. If I recall they even tryed to install a skeg in the keel to help it turn, like the flat bottoms. Dennis purchased and then rigged it with 5's on boxes. As far as being a fast boat with the Arnesons I guess that is very possible. Maybe not fast around a race course? I had another friend with a 33 with blower motors and Arnesons and I believe that boat was at 110+. Sutphen has a fast bottom and provides it's own lift, but I am not sure how the hull reacts in turns and during re-entry with the drive.
