Great to hear about your journey.
You mentioned good experience with ultrasonic antifouling earlier. I thought that we have a sandwich construction of the hull made installment difficult. How did you solve that ? Anyone else have experience with ultrasonic antifouling ?

12 weeks static in water of more than 30C, using ultrasonic with two transponders. Hull clean with just a light slime, but saildrive as can be seen. Discussion with manufacturer suggests that maybe the seal between hull and saildrive is stopping the signal. Am going to relocate transponder nearer to saildrive to see what happens.
Transponder is glued to bottom of bilge and transmits thru the hull.
Saildrive now clean by diving, and hull ready for the winter season here in Dubai, started last week with Barts Bash.
PS background is the marina and under the dock live many angel fish feeding off the growth.

Hey rod, my hull was covered in rubbish when we lifted her out for transport to turkey, proof that your ultrasonics worked as ewe were all of 10 meters away. What make is it, I might get some fitted.

Mark, the make is Sonihull from NRG. Now I have to figure out the sail drive.
How's Turkey? In cruise mode yet?

Hi to Panos and Alain and other very helpful inputs.

I think Panos owes me a case of beer, collection point to be agreed.

We took the prop off this morning (underwater).

1. Two of the blades feel a bit rough, can move / rock slightly on their bearings. I will be taking the prop back to UK in my luggage, there goes my weight allowance!

2, We ran the engine at various speeds, no vibration, the diver (an experienced engineer) is certain the shaft is true and straight.  HOWEVER he said he can hear roughness in the bearings in the races.

3. Gear oil is seeping out slowly when the shaft is turning. I knew we were still losing because even now at rest my oil feed system is going down. I should explain this; in Trinidad with the help of the local Yanmar engineers we tapped and fitted a nipple to the top screw in the sail drive, and connected via a tube to a small oil reservoir bottle. This gets us away from the expansion problem suffered by these drives as the oil can expand up and down the tube.

4. I discovered a pool of what feels like gear oil in the pan space under the engine.  Not 2-3 litres, I don't know whether it is coming from, the sail drive or how it is getting there. I think most of the oil loss is via the seals and bearings on the shaft.

Alain, you briefly mentioned oil getting past the seal between the engine and the sail drive.  Also the adjustment of the shims.  Can you elaborate in great deal what a novice is going to find and what I will have to do to repair the damage?  What components will I need to buy in UK to make a safe repair?

Thanks to all for the really helpful insights and advice,

Graeme and Camille, in Paradise

Reference Ultrasonic Antifouling

I assume you are talking about a standard Hanse hull.  Ours is epoxy biut I wouldn't think that would make any difference. I think there may be a problem iif the hull is laminated with a foam sandwich between the layers.

Otherwise it is still performing as it should. The diver complained to me this morning to please turn off the ultrasound as it was echoing in his skull.  We get a bit of slime along the waterline and I still get bits in the log wheel sometimes.  But when the prop came off this morning its on;y going to need a bit of a scrub and polish to take it to the manufacturers.

When we were in Trinidad, Curacao and Aruba we could have sold and fitted several dozen units if that way inclined.

Regards, Graeme

For your interest, we have two JAYCAR kits fitted.  One is directly over the saildrive the other is forward of the keel.  My saildrive is CLEAN after tropical waters for 12 months. No growth inside saildrive. No growth on prop.

Jaycar reference is:-

We fitted two of the £90 kits.

Where are you now? I'm always happy to win or to loose a case of beer!

Graeme something else for your hand luggage,the prop shaft no doubt has two rings worn in where the seals touch.
The shaft diameter is 34 mm have it machined down to 32 mm you buy new seals that size from any bearing supplier,make sure you ask for ones with a stainless spring though
