took my boat out for its first run since putting piranah prop. so far great. runs smooth, picked up a couple mph at top speed. comes out of the hole better i think than with the oem prop...kc
Ian glad to read that someone else is happy and using a Piranah prop. I've got them on both of the boats that I own, and will never go back to any other. The abilty to switch blades an or pitch on the water has been a real benifit for me. I've hit things that would realy mess up things and never have been left out in the cold. Most of the water I go on is only 4 ft. deep with rock bottom, not a freind to props nor lower units. More than once I've had to tow others in. Have fun on the water and be SAFE.
the boat is a 1985 invader, aq125b 4 cyl volvo/ 270 outdrive. prop is 14x19 old prop 4500rpm = 32mph, new prop 4500rpm = 34 mph same lake same conditions. now i am ordering the extra blades..
Just wondering,could you give us the details on the boat and outdrive.
ie:size,dryweight, horsepower,max rated rpm, gear ratio,usually stamped on the leg.
