Yea 28s.
last test was with 28 Bravo's. They were pigs. Witj The 275 hp tune got 5300 rpm @ 73 mph if I recall. Slip numbers were very very low. Like 5%. Max rpm currently is 6400
Gonna see what these will do. Should get the rpm up...but idk if the slip will be too much. I hear they run great on the shadow OB cats tho who knows...might see 80 with the right props.
Gonna have to send ecms overseas to get the 325 hp tune now lol
Might try the hill 28 4 blades of these don't pan out
