Yep

I bought a 25 Convincor from them a couple yrs back and have know them for 30 yrs.
Can’t believe I didn’t think of them for this thread...

They had a 25’ running mid/high 120’s 20 yrs ago.

Dude, grab a beer, go to you tube and search “Australia Ski Racing” and enjoy.

Some of The spectator video shot from the river banks is off the hook.

Look up the “Bridge to Bridge”.
One of their most famous.
60 mls, River bends, narrow ass passes, no stops, full zoot!

Im an OB guy and their stuff is crazy.

Their IO hardware is beyond what I’ve seen in the states.
And, pull up two slalom skiers from a deep water start, hold your foot on the floor, race 30 mls up a river, do a u turn and come back!

Their is also some spectator video of a guy that ran an offshore cat in the Bridge to Bridge and spun at a turn where there were spectators in water filming that had to dive out of the way!

Still on my bucket list.

I had a 26' 1998 260 so basically the 280. I ran a ProCharged built 454 aluminum heads, larger injectors, etc. Dynoed 720HP and 727 TQ with 685 TQ at 2800. I ran a B-Max with 1.30 gears spinning a 30 at almost 5300 RPM. Ran 94.8 GPS
