Yes - Harry Harrison in Grey Lynn. Very approachable and excellent, considered work at a reasonable price. Harry Harrison harrih@xtra.co.nz Also I have known him for years and he has done work with me. That's the only connection BTW

I have now setup a new website www.jorgensenboats.nz - a repository for all things relating specifically to boats built by Jorgensen and Sons of Waikawa Bay, Picton. As owner of Peter (Pop) Jorgensen’s yacht Stormbird I am fascinated by and admire Jorgensen boats and I would like their history to be preserved in a publicly accessible form. I am asking around for anyone connected to the yard by way of the people that worked there and past and present boat owners to contact me so I can include their information - pictures, anecdotes, technical information, refurbishment notes, present

Volvo?

Does salt on and in the fabric make any difference to it being for marine or motorcycle?

Bio Magic additive from Burnsco

You wouldn't need one.

I would prefer the boat next to mine has, like mine, a gas certificate as well as EWOF

Thanks Fish - good pics and explanation. Counts me out though as I don't have a strut.

Ah huh - brilliant then that's the problem! and I will replace the cutless bearing. Last time I removed it with a slide hammer cutting a slot in it first with hand held hacksaw blade. The boat has the prop in an aperture which is a bit of a bugger cos to get the shaft forward enough to remove the bearing the engine has to be lifted and moved forward or possibly get away with removing the gearbox (uncharted territory). Thanks for the offer of the puller might take up you up on that - the size is right. Would you be able to send a pic and I can quickly see if it will be of use due to the sm

Yes but all those are isolated eg there are no mixed metals in contact with each other under the water. Fastners are isolated, bronze though hulls are isolated, s/s rudder shaft is isolated from bronze bearing at the lower end. There is an electrical path with resistance from the prop shaft to the stuffing box and cutless bearing - not sure why except perhaps because they are close to each other and the salt water is conducting. The only thing that isn't isolated is the prop and shaft which are dissimilar metals and the prop degrades over time but will last for 10 years or more

Getting bit off topic here because what I would like to know is and my original question is .....has anyone seen scale/calcification build up on the prop shaft inside the cutless bearing? But re the anodes rule - number one is don't mix metals under water - lots of info at Waitemata Woodys https://waitematawoodys.com/2015/05/15/electrochemical-damage-to-wood-the-marine-version-of-leaky-homes/

Wooden carvel boat. Anode = even more trouble - its cheaper to buy a new prop every now and than fix the stern timber area from degradation
-
The only other thing is that researching this I realised the cutless bearing has a brass shell part number which will be in contact with the copper stern tube and if it really is brass it will be breaking down. (5 yrs old) No anode fitted anywhere. So will replace with a phenolic one and have a good look at everything at that time (now soon)
