My '89 DD has a left hand prop, and the rudder is offset about one inch to the left of the propshaft. Can someone explain why? (I have a theory, but I'm not going to say anything for fear of sounding stupid. Again.:))

To get the shaft out without having to remove the rudder.

That's it? Aren't there any other explanations involving irreconcilable prop torque, torque thrust, centrifugal force, or the coriolis effect?

LOL, that is what I heard. But I will let someone else provide the more complicated answers, if there are any.... :confused:

Next question: If I have a LH prop and my rudder is offset to the left, do those of you out there with RH props have the rudder offset to the right?

It's off center so it's not sitting in the pocket of air directly behind the prop that truns into prop wash a little futher back.

So you're telling me all the boats on here have this???

I suspect not. BIGGER boats, yes. On a MasterCraft I think the answer is - that's just where it all bolted up. These boats are hand built.

I think I recall reading that it's a combination of this and easy removal.

A dealer once told me it's to help them track straight as well, to offset the prop rotation. Not sure I buy it.

I actually got that from here a while ago, it's been asked a few time since I've been here :D

Every V-drive I've ever owned has been this way. It's not just Mastercrafts.

I got a more detailed explanation from the RC boat crowd.

One reason the rudder is offset. There has to be some type of torque on the rudder that allows the driver to hold the boat straight. If the rudder was directly behind the prop it would have a tendency to fludder. Having is slightly offset set allows flutter not to happen

Time to BUY BUY BUY...Then SELL SELL SELL


The idea of EASY REMOVAL is pure HYPE...not the reason at all

I thought mine being off center was just a quality control issue...............

Thanks Jim! An answer that makes sense!

Any explanation as to why it's offset to the left and not to the right?

I'm glad to hear that I'm not the only one with this problem. I've been calling MC for years trying to get this fixed! :D


I'd bet that I could go to my MC dealer and ask 3 guys why the rudder is offset and get 3 different answers. What ever the true reason is, I like the fact that it does make it quicker to pull the prop shaft.

Time to go outside and winterize the boat. Air temps are only in the low 40/50s and the water was the same last weekend.:mad::mad::mad:

I'm sure the toy boat forums are a hot bed of information, never thought of that :D

That is the same reason I have heard over the years as well. I never have heard that one real reason inboard makers do it is for easy DS removal, but it is a good side effect.

So how does Correct Craft get away with it?? All the rudders I have seen on those are right in the middle?

Are you just looking for answers or the right answer???

I dont know...I am not a Correct Craft dealer. I will tell you that a CC turns much better to the left vs. to the right...I guess they cant do everything CORRECT ly HA HA HA

That's true. Unfortunately, my father in law's MC does the same thing at slower speeds.
