whats the right prop

[mdegood]

I have a 2001 evinrude 200 hp with a modified lower unit (shallow water) with hyd jack plate. It is mounted on a 22' Hydro sport LTS with the tunnel hull. I am not sure what the max rpm's are. (i think @5500 rpm). I have noticed that on a tight turn I am getting alot of cavitation and power loss. The boat seems to be running slow with high rpms. It has a 3 blade prop and I have no idea of the pitch. I am wanting a good all around prop that will give me some performance speed but not totally rob what fuel economy. Any ideas?<br /><br />Thanks,<br />Mark

The best possible advise i could guess is that i would probally use a 141/4 x 19 or a 141/8x21 4blade cyclone depending on weight of the boat

Howdy.<br /><br />What you are getting is ventilation. The prop is grabbing air and making foam.<br /><br />The most probable cause is that the prop is too high or trimmed out too far.<br /><br />Changing props would do no good without first getting it into the water.<br /><br />Good luck.

I had that on my boat. A larger diameter prop pitched down one notch helped. How is your hole shot? ( I went from a 13 x 19 to a 14 x 17) Lost 2 mph at the top end, but got better hole shot and no cavitation.

you may want to try an OMC shooter or Renegade 4 blade for the best of both worlds

Before you go spending a ton of money on a prop, my recommendation would be the same as JB's...Drop the heigth a little and see what happens first.<br />You don't have a transducer or speed sensor within 12" of center on either side, do you???
