there are two different designs to those dolefins. One that I had looked like a birds wing and when installed it was perpendicular to the cav. plate/lower unit. I thought it worked well, a good 39.00$ upgrade. The other design is that the "fin" looks kinda like a big flat paddle that mounts sorta inline with the cav. plate. On a larger, heavier boat I somehow think the second one mentioned would work better on a v20 or similar. Can't say I like how they look, but on my little 16' slickcraft w/ 85hp v-4 'rude it made a difference for the better.
