Has anyone got experience of using doel fins on outboards. What if any improvement is to be found in the boats performance?<br /><br />I use my boat on a river where the speed limit is 5mph. Would a doel fin be any good?
What is the best height for the cavitaion plate on my 30hp evinrude below the keel of my 22' Teal crusier. I have a feeling that the transon is to low. I think the engine has a 20" shaft.<br /><br />Thanks Alistair
