Minimum Planing Speed

[76Red18]

I have used the doelfin and currently we just put a stingray fin ($48)from West Marine on the new Zuke 140 on an 18SF. The planning speed dropped nicely and the fin does lift the stern up on take-off. There is no noticeable digging-in at turns and the extra side to side wing length vs. a more narrow one should only improve it's function. The narrow plates work great just different.

That priced model looks to be the drill holes to mount model. No concernes about doing that to an under warrenty motor. Mines an old 150 so I don't care. What that Suzuki weigh? I think my Johnsons about 375. Were probably close in performance except for 1 big factor; fuel economy. I get about 2mpg max.
