Does anyone have a diagram of a twin prop rotation set-up......im asuming the left hand prop as you look at it from the back goes anti clockwise and the right goes clockwise.
Also which is the left and right prop (3 blade identification) Does the left one have the straight edge on the right???
Sorry for the novice questions guys,

Hi Ad
If you place the Prop nose down on the table use the following,
If it's a right handed prop then the the flat part will be on the right and the curved bit will rise to the left.

I might be wrong here but is that not a left hand prop in the picture?

Depends on if you want the wash running inboard or outboard i guess.

That is actually a Right hand prop but it's viewed head on (with the pointy bit in front)
I'm sorry but my picture shows nose up, not down as written about.
Apologies for the mistake

Much of the rudder response on a twin screwed vessel will depend on the fore and aft location of the prop shafts. If they converge towards the motors then the prop wash could easily "miss" the rudder. If that's the case then inward turning props could be the answer. But again, a lot of handling problems, single and twin screw, come from the ships (or model) "turning or pivot point. Weight too far forward and no matter what you do she will always handle like a pig. Converesly, weight too far aft and she will be so "twitchy" it will be almost impossible to steer in a straight line. BY.
