View Full Version : Rudder offset about 1" to port on 90 PS190?

Hey guys, fill me in on why the rudder is offset about 1-1/2" to port from the centerline of the shaft on my 1990 ProStar 190(appears to be factory-no prior damage). Could this be an engineeered attempt to somewhat counteract the "port-drift" while backing? My 1985 "Stars & Stripes" 19 has the rudder perfectly inline with the shaft. Why the design change? My 85 was purchased from "Bouy-Chaser" last month and is such a NICE boat.

The one reason I know is to allow for easier removal of the drive shaft. Earlier models required remoavl of the rudder to accomplish this task.

I don't know if this is true but I heard that it puts the rudder in a better position in the prop wash than directly behind the prop, which has a "dead" spot.

Makes it easer/possible to dip it in the pitcher when making frozen Margaritas (personally I prefer “on the rocks”)

Oh, as well as allowing the shaft removal thing..

Not exactly the "theoretical" reason, but cover's the bases. The prop creates a "pocket" of air around it's center (essentially cavitation) and the rudder is offset to get it outside of this area where it will be more effective..

I always thought it was to counter the rotation of the prop , Prop has a tendancy to make you turn one way & having the rudder off center counters that tendancy. I could be wrong , just what I assumed or was told a long time ago. :)

Yea, that might just happen! However, As I have tried to teach you in the past, Its not WHAT you know, but WHO you know. If'n we was to get thrown into the gray bar motel here in BWK, then we gots NO problem, as the high sheriff is a CLOSE friend of mine! He's got me out of more crap than Carters got them little pills! :D As a matter of fact, the local traffic court Judge told him he didn't wanna see that Wildsmith name ANY more for a long time! :eek: Now, that might be bad! As far as the rudder goes( back on track), ya'll just come on down to So. GA. for about a long weekend, and lets see just what we can git into! :toast:

If Dog drives all the way up there and I haven't changed out that damn rudder by then, then you can bet your a$$ that we'll be a changing it there! BTW, Wakebroad needs to be the rep. from the west! We need her talents in the body shot department! We won't accept ANY subsitutes! :woohoo:
