Hey everyone,
I will be testing the three props below tomorrow on my 2006 LSV with the 325 HP engine (same boat as current LSV) and would like your input on my test protocol:
OJ #454 – 13.7 x 17.5, 0.110 cup (stock prop)
Acme #537 – 13.5 x 16, 0.105 cup
OJ #466 – 14.25 x 14, 0.090 cup (wakeboard prop)
I bought the 537 from tazz over the winter and mandley was nice enough to let me borrow his wakeboard prop for the purpose of this test (not that he needs it right now :).
The reason for the prop testing is that I am looking for a prop with a little more holeshot because last year, I found the limits of my stock prop. I had 1400 lbs of ballast full and 7 adults on the boat plus 1 behind the boat that I was trying to get up on a wakeboard. It took about two minutes for the boat to plane out.
Of course, the wakeboard prop would take care of any holeshot concerns but since I do most of my boating with light loads, I’m not sure I want to pay the gas usage penalty as well as give up several mph on the top end all the time. So I hear that the 13.5 x 16 is a good prop that is in between the stock and the all out wakeboard prop. This was the prop suggested by both my dealer and nettle props when I described to them my boating habits.
Below is the data that I plan to record for each prop. I am not concerned about wakesurfing – I have no trouble getting to 10 mph with a boat full of people and the surf ballast filled and I only pull up at partial throttle anyway when surfing so I see no value in upgrading the prop for surfing only (sorry Ed :).
Please review the list below and let me know if I am missing anything. I am using 23 mph as my test speed as that’s the speed I normally ride at. Note that the first series of tests is with ballast empty – only the last set is with ballast full. I am going to fill my three wakeboard sacs full (1400lbs) plus I’m going to fill my 750# sac full and put it right in the center of the boat between the driver’s and the observer’s seat to simulate people weight as only me and my son will be on board.
