Volvo saildrive

[Laysula]

Hi all
Our boat is coming out of the water on Friday to be scrubbed and antifouled. I expect that I will have to replace the anode on the saildrive,cananyone give me any advice on what this entails before I see it out of the water,I expect that the prop will have to come off Is this a nut and split pin? How is the anode fastend are the bolts likely to be corroded?and hex head/socket head or crosshead and will I need any special tools?
cheers Steve

I have a Volvo 2001 with saildrive. To change the anode prop has to come off and on to do that on mine you undo a locking nut then the main nut. You need a socket set for that. I can't remeber the size but was quite large. Before that to get access have to take blades off and that needs an Allen key on mine. The actual anode is held on with three machine screws. There will be anodes on the prop as well. Its not difficult.

Mine's nothing like Simons .... which isn't going to help you /forums/images/graemlins/frown.gif

Volvo 2020 with 120S saildrive.

The prop is held on with a spin-on cone which in turn is held on by a long stainless steel bolt.

Undo the bolt using an allen key.

The cone spins off anti-clockwise. You need to jam the prop and put a screwdriver through a hole drilled in the cone to get it free.

The prop is located on splines and just slides off.

The anode is held on by 2 or 3 phillips screws.

No special tools required, just a bit of luck that everything is 'free'.

Essential that you replace the s/s bolt or at least loctite it back on.

Dont forget the locktight for the machine screws and oil drain screw. have seen the screws backing off when the anode starts to wear and damage done to casing

Simon is describing a folding prop, and this varies by make. Bav 34 is for a standard fixed prop. So you need to know which it is - obvious when it is out of the water. The anode on the leg is the same, but fixed props do not have a separate anode. If you have a rope cutter fitted you will need a modified anode from Ambassador Marine.

If it's a folding prop the main nut is 24mm so make sure you have a big enough socket. Main anode is held on with cross head machine screws.

Cheers for that
I have a fixed two bladed prop on a 2010 engine any idea what size the nut is on that?

Does not have a nut. See Bav 34 description above.

On a charter boat I frequently had a loose anode spinning round. I cured it by buying same size SS screws but with Allen key head. I find an allen key gives more torque than a phillips screwdriver. I never had one of these come off.

Always use locktight or similar on threads
