Hey gang - I am curious about performance with an upgrade to a duo prop with a Volvo 270. It's for my 69 Corsican with 351 Cleveland all upgraded. Currently running a 19 Solas at about 5700 rpm at 55 mph. (Was getting 52 mph at 4400 rpm with 21 Soals.)
Will my performance be substantially better with duo setup and are there any other issues to consider?
thx
