jwalker - I think Manos may have got it the wrong way round - he was replying to me where I said that it may get ripped off the cavitation plate.

I always thought they were the same thing - but the result is the same anyway!

my experience of these devices is admittedly a little old, and they certainly (to my knowledge) didn't do them for "bigger" engines then! Impressed they give you more top speed on your boat - do you get other benefits as well, such as earlier and slower planing speeds?

Not read in a sales leaflet - a simple fact from experience of fitting one

When throttling back you can keep it just on the plane at very slow speeds, which is usefull approaching inlets when you need to think about slowing down

Are we talking about the flat fin or the gull-wing shape fin here?

I've just noticed that Pepper seems to have a doelfin fitted to his 18hp on his 3.6 SIB (see the for sale section).

Pepper - how do you find it affects the boat and it's performance? Would YOU recommend fitting one to a smaller boat?

I presume that it could be removed if it did not work.
