as in title im looking for a new prop for my yam its got a standard 9 7/8 x 10.5 allt prop as std
its goint on a cesar mini cat 3.0 mtr rib (like zapcat)
at the moment i can only get traction trimmed right in i get prop slip and lots of bow lift if i trim out more
also the engine is down on the transom not raised
and the cavitation plate is just about on or slightly below the water line
its hitting 26.8 mph
iver seen on the web an 18hp on the same boat doing 56kmph and a 30hp hitting 76kmph one had a 13p prop the other a 15
i think ive read semi cleavers are the best for tunnel hulled boats as the prop is in so little water?
any advise welcome
