OK Guys,

I have been thinking of using this on the 18' Raider. The boat lends itself to towing (with its tow-bar) and going fast with its 200HP motor.

I was looking at this and it seems like it would do the trick. I have tried to tow with my (now gone) Montauk and it had a 19" pitch prop that did not tow well at all... Plus with all the talk about picking the right prop in the performance forum this might generate some intersting discustion on slip, trim, angle of atack etc.

Interesting read.

Was that really an article, or an advertorial?

Buckda,

I agree, he seemed have liked it a bit too much. I don't know much about Powerboat Magazine it could just a paid ad rag.

I search the net for any "down-side" information and the only thing I found was the issue of high cost.

land-and-sea had a lot of "independent" write ups, but this was the best one to explain the shift=trim system. The others seem to talk about speed to plane numbers [about of fixed] (and water skiing benefits)
