Can I remove the propshaft without removing the rudder. Oceanis 40

Does anyone know (100% sure) if I can remove the propshaft without removing the rudder on my Beneteau Oceanis 40?

I can't imagine how - isn't the shaft directly in line with the spade rudder?

Sometimes I believe the shaft log can be removed and it can be done that way.
Shaft is in line with the rudder on my IP, but it can just barely make it if the shaft log is removed. There may even be enough variation in production that may not always be possible.

pull the prop, pull the engine, and slide it out through the engine room.

if this is harder than pulling the rudder, you might as well take the rudder off.

Hi guys. Yes it may be possible if the stern gland and cutlass bearing is removed. That might allow sufficient movement to get it past the rudder. But that much I already know.

I really just want to hear from someone who can confirm it either way.

THE METHOD YOU OUTLINED ABOVE IS EXACTLY HOW I REMOVED THE SHAFT ON MY 2005 BENETEAU 50.

HOWEVER, IF YOU ARE REMOVING THE SHAFT IT IS A GOOD IDEA TO REMOVE THE RUDDER AND REPLACE THE LOWER AND UPPER RUDDER BEARINGS. BENETEAU USES VERY THIN CHEAP BRONZE LOWER BEARINGS (A SIMPLE SLEEVE) THAT WEARS OUT VERY QUICKLY.

WHEN WORN, IT HAS A TENDENCY TO EGG SHAPE THE RUDDER SHAFT OR ENLARGE THE FRP BEARING SUPPORT IN THE HULL IF LEFT IN PLACE TOO LONG.

I HAD A MACHINIST MAKE ME A SOLID HEAVIER GAUGE CYLINDRICAL BRONZE BEARING.

THE STEERING NOW IS MUCH TIGHTER AND MORE PRECISE. IN ADDITION, THE AUTO PILOT IS ALSO MORE PRECISE AND LESS ACTIVE (MINIMAL HUNTING AND COURSE CORRECTIONS), THUS SAVING A LOT OF BATTERY POWER. THIS IS NOT AN EXPENSIVE FIX OR UPGRADE.

GOOD LUCK

Sorry if I'm appearing to barge in here, but a very poor design if you cannot.
I've replaced the Shaft on my Irwin43 twice in past 20 years.
Remove Prop, Uncouple from engine and it slides by the skeg mounted rudder.

I have a Beneteau 473 - and have just changed the stern gland and bearing I definitely had to drop the rudder , it does not clear , not even close . Dropping the rudder was quick and easy .

Re: Can I remove the propshaft without removing the rudder. Oceanis 40

I did it on my Oceanus 382 when the yard told me they would have to drop the rudder (at great expense) they started but I went down the following morning and pulled it out. On mine I pulled it back to the rudder. When it got that far out I was able to tilt it down a bit , turn the rudder and out she dropped. I walked into the office and handed it to them and told them their chief mechanic didn't know what he was talking about. they still tried to charge me for unhooking and then hooking up the top of my rudder.

I sure hope you didn't pay! I have a real dislike for being charged when it wasn't necessary..
