My question is do dolphin fins create back pressure towards the transom, I think a liewell hose is leaking and thought if the fin produced back pressure it would leak more!
If you have alive well hose leaking, back pressure from a dolefin(if there is any) is the least of your concerns.
If your hose is leaking it's allready compromised and needs to be replaced NOW. when that hose fails completely your boat will go directly to the bottom.
