bravo one drive wrong side?
 
ok i have a 35 fountain ex with 496's bravo drives.I just took off the props to have them tweeked for the winter.The starboard prop is on the portside and the portside is on the starboard side.I have owned the boat since new never have removed the drives.Is this correct or do I swap the drives? Or is this a fountain set up?

If what you are seeing are the props turning "IN", then it's a normal Fountain set up.

i dont understand question?? Do you take your lunch or walk to work?

sonic28 10-01-2010 01:53 PM

ok lets try this the port prop is on the starboard side and the starboard prop is on the port side!The question is this normal on fountains?I do know if I swap the props around when you put forward the boat goes reverse.nope I drove to work and bought my lunch.

No such thing as Port and Starboard props, just left and right:grinser010:

I believe you are saying you heve a left handed prop on the starboard side, and a right handed prop on the port side, if so this is normal for fountain.

thank you but why would they do that?

Turn in to WIN:drink:

I still dont get how swapping drives has to do with props ?? if you put boat in gear and go backwards props are on wrong..switch em no?? easier to change a prop than a drive..

As a very general rule:

Props turning in raises the transom when on plane compared to turning props out when lowers the transom and raises the bow.

Fountains are normally set up to turn in as tuned with the props and hull.

Other boats are normally set up to turn out, also as tuned by props and the hull.

Sydwayz, thanks for actually giving an answer.
To expand a little on this Reggie started turning the props inward (for the reasons you stated) on the high powered turbo boats back in the 80s when 100mph was king of the hill. The early boats had so much lift in the pad for running 70s/80s the nose resisted lifting at the higher speeds. Standard powered boats still turned outward.
Some side effects are if the boat tries to chine walk the outward turning props help stabilize it and inward turning props make it worse. Also, around the dock the boat does not twist on its engines as well with the props turning inward.
Cats have to be especially careful running the props inward; if you launch and come down tilted on one sponson a high pitch prop will paddlewheel and try to corkscrew the boat over on its back.
