6 drive owners ???
 

when your boat is at rest how far below the waters surface is the top of your cavitation plate?? also what type of boat...no exacts neccesary just a ballpark...

thanks

Ttt

Man, I would have to check. We use them to sit on when we are floating...:drink: Less than a foot I would guess. Let me look at some pics and see if I have some that show it.

been wondering the same thing myself. Measured many boats through last summer and came up with a pretty broad range pending hull type. Cat Vs. Vee Vs. staggered Vee etc.

I should have been a little more specific......with the drives tucked all the way in and at the trailing edge of the plate......

thanks

There are so many variables it would be hard to get a uniform response.

Why are you interested?

+1

Not sure what the purpose of the excersize may be here. At rest can very greatly even in one boat, due to passenger load, fuel load, beer/cooler load :D, and ballast tanks...

... not to mention one boat compared to another of same make/model that might be made of kevlar vs. C/F vs. fiberglass vs. resin; as well as traditional layup vs. vacuum bagging; etc. etc.

Then comparing different boats and types (Vs/Cats/manufacturers/lengths) would produce a WIDE spread result here.

Are you looking to develop a swim step that bolts to the cavitation plate?

Or possibly developing Hydrofoil available at West Marine and Wal*Mart to improve the performance of your VI boat? :D :D

the top of our drives (tie bars) are right at the top of water when just sitting. (drives about parallel with bottom of boat.

I have an idea on tight quarter, slow speed manuverability........would it be a safe bet that most are at least 8 inches below the waterline?
again not looking for exacts just a ballpark......most of our boats around here are still in dry dock...

I would say most are at least 8" below the water line

:drink:

anyone have a six close by? what is the distance from the top of the gear case to the top of the cavitation plate?

About 18.5 " !!! ruffly

Thanks....

Old style is 11" new style +1" or 2". The drive shaft to prop shaft is 18.5"or 19"

Your right about the Propshaft to driveyoke !!! Missunderstood that ,,,but what is the difrents in the housing between an old and new style six ???? They should be the same exept for the sweptback on the lower ?!:party-smiley-004:

They raise the top so the gear can be switched for left or right hand rotation. The old style switched rotation in the lower like the other speed masters. early style tie bar mounts to the back of the upper case new style mounts to top.

WOW,,,they look the same but ,,,yeah . Looks like u know what your talking about ,,,sorry if i messt something up.:cool:
