Beware a two blade prop !!!!
Sasha :Do yourself a big favour & get a 3 blade prop for your 390!!!Although our experiance is with a Flex-A Fold, no doubt you'll have the same experiance with a Gori. When Winpipe (our B361) was delivered in june 2001, we removed the fixed 3 blade prop & put on a 2 blade Flex-a-Fold.It ""shook"" the boat something feirce & so we changed to a Flex-a-Fold 3 blade when we launched this year & it runs as sooooth as can be.We would NEVER encourage anyone to get a two blade prop as a result of our experiance.Also, bear in mind that the boat comes with a three blade prop from the factory...there's got to be a reason !!!Fair winds,Paul Ouellette,www.winpipe.ca
