There should also be a hose from the valve part of the anti-siphon valve guiding any water down to the bilge, instead of squirting it all over the engine. The small hosetail: https://webshop.vetus.com/en/product/asdv-anti-syphon-device-with-valve-13-32-mm

Mine had a little bottle tied to it, so I know when the valve needed cleaning. Also less mystery leak hunting that way.

With regard to the anti siphon valve.. the latest VP model is creating far less problems than the old model. If you can spare the money, would recommend to exchange for the latest VP model.

The anti siphon valve only needs  maintenance. Take a look in the manual, its easy to do.

Thanks again symphony2 another good suggestion. I have found the source of the problem, the anti siphon/vacuum valve is dribbling water at idle and supporting it out at anything over 1500rpm. Of course this is going over the fuel pump etc on the starboard side of the engine. Will install a new anti siphon valve and hope this fixes the problem.

Modifications & Equipment / Propellor cone and prop. loss

Last post by Rapita - March 29 2026, 14:24

I have read various posts here, also a recent article in PBO about propellor loss.Apparently VP now supply a new cone and locking bolt with a metal tab to lock the bolt in place,about £100.Apparently making it more secure.
Our boat is a B34 ,md 2030 powered with sail drive.

I read a previous ingenious post here about drilling the cone and bolt to fit a roll pin which provides locking security.

I just noticed on another site that Orbitrade sell a lock washer (part no.19367)to fit under the cone with the tabs available to bend up into cut outs in the cone.

Do you think this would work on a saildrive?

Would the tabs cause more chance of picking up debris?

Thanks in advance of any opinions

You may want to check the outlet spigot of the exhaust muffler as this tends to corrode leaving pinholes that leak seawater when the engine is running. That ends up in the bilge under the engine.

Thanks for the answers really appreciate the detailed response. I'm not sure how seawater has reached the fuel pump, perhaps evaporated seawater... I will clean these up with my Dremel and use rust converter plus paint.
I suspect the sail drive ring bolts are vibrating loose and nipped them up yesterday about a quarter turn on each one on the port side. There has been about 100ml of seawater in the engine bilge after a day sail with 1hr motoring. I clean this up after every sail so hopefully the problem is resolved for a period of time.

Thanks for the clarity on this question, very pleased to hear there is nothing needed. Just had new anti foul done with a 30cm coating of Jotun aluminium surrounding the rudder.

See my reply to your other question. The anode on the hull should show minimal depletion as it is not in a galvanic cell. The saildrive anode should show some signs of depletion, although this varies from location to location. Make sure there is good electrical contact through the mounting bolts and the face of the housing. Check for continuity. As already suggested the corrosion on the engine and drive bits inside the boat are result of damp salt water  - maybe a leak at some time in the past. The verdigris on the intake is quite normal and should clean off easily.
