Steve,
I love the short small hull in the surf.. With a flush plate that comes on the hull which is perfect for flatwater sucks in the surf. You fight the nose high, wants to tail stand all the time. You can ride it, but your fighting it more than enjoying it..
Add a long plate, makes it fun to ride, no tail standing, re entry's , backflips, rolls, stabs in the surf are no problem... Now take the ski to the lake, 5 minutes to swap ride plates and your off and riding, backflip , rolling, etc on flatwater with the same ski...
As for my reduction / nozzle setup that's my own setup... Yamaha reduction custom bore, protec steering nozzle with custom bore, thrust trim...
Ski rips... Can't wait to tweak this motor and swap pumps...
