  1. Combined effort. I had a mate help with the welding and he CNC machined the manifold flanges.
  2. I promised I would share some photos so here they are. New exhaust manifold fabricated from Schedule 40 pipe and the exhaust pipe and mixing elbow. Fitted it all up and tried it out on Saturday and it works perfectly.
  3. Talking about sanding antifoul, I have found using a tungsten blade paint scraper really handy for tidying up after water blasting. I have previously sanded (using No 5), but one of the guys in the haulout yard suggested I try this, and it worked a charm. Just takes a light run over to shift any lumps and bumps. I should say I'm not looking for a mirror finish but it was a huge time saver.
  4. Thanks again for the replies. Fish, the contact for The Engine Room sounds worth a follow up and Frank, that was a useful link you provided. All good info. I'm breaking the job into two parts. The first is to fabricate a new manifold for the engine, replicating the original one as closely as possible, but in stainless. While we are doing that I'll investigate the options for the riser and mixing elbow. There's a bit of a plan taking shape, so I hopefully I'll be able to share some photos before too long (and be back on the water).
  5. Thanks for the replies. I have somebody lined up to help with the fabrication. He's a first class welder and machinist, though not much marine experience. We have a plan for making a new manifold and intend to keep that separate to the riser and mixer to make future repairs easier. I'm still not happy with the idea of hot salt water sitting in the bottom of the riser and condensing into the exhaust manifold as the engine cools, so I'm keen to see if there's a better way to do it. The previous owner had exhaust valve problems and had to do a head overhaul, so I suspect the current set
  6. Sadly the exhaust manifold and mixer on my engine has reached the end of its life and has failed fairly dramatically. The engine is an older Isuzu and the original cast iron manifold has corroded fairly dramatically to the point where it broke (fell) in half while dismantling. You will see in the attached photo there is a stainless water jacketed riser and mixing elbow which are custom made. The water jacket is really just a second point of injection into a well which the exhaust gases flow through, rather than a proper jacket. Parts for the Isuzu are hard to come by, so it looks as if w

  8. Likewise. Was with Youi, then transferred to Tower when they bought Youi's customers, then dumped by Tower when the policy expired. In my case no offer to switch over to Club Marine though.
  9. I have the same unit and while it's working OK the aluminium plate has become quite corroded. I had a go at removing the whole unit but gave up after removing the screws on the face plate and finding it was still well attached. It was going to be more complicated than I had time for that day so it's gone to the to-do list, but some maintenance is probably well overdue. To save me some mucking around, is somebody able to advise the best way to detach and remove the unit please? I'm thinking it may be fastened from behind where I can't see. Thanks.
  10. I'm also looking for a new insurer since Youi sold out to Tower. Have just received notification from Tower that they will no longer provide cover. I have checked with Nautical and they won't provide cover on a swing mooring. No luck either with State who I have my car and house with. Some helpful info in this thread, but I get the feeling it may be going to take some time and research to get this sorted. Boat is a Spencer 28 built in 1979. I also have had suggestions to check with Mariner and Club Marine. Does anyone have experience with them? Good, bad or otherwise. Any other sugge
  11. Try a CRC product called 'Peel It'. It's a citrus oil based label remover. Worked well for me. Some Mitre 10s sell it but you can probably find it elsewhere online at present.

    Sail cover

    Looking for recommendations about where to have a new sail cover made in Christchurch. Any suggestions?
  13. I have my now 40 year old boat insured with Youi. No unreasonable questions asked, no survey required, happy to insure on a swing mooring, and the price seems competitive. It looks like all insurance premiums are taking a hike though. My business insurance (through State) jumped 25% this year. No claims and it seems other companies have made similar increases. Always worth shopping around.
  14. I had a break in last year. Toolbox stolen, and a torch, but the electronics weren't touched. Whoever it was broke the hasp off the hatch cover - probably with a large screwdriver. Not hard to get in if you really want to, and I agree with Puff about more damage if you make it harder. Since than I have put in an alarm siren that will sound if the washboards are lifted. There is a concealed switch in the cockpit to set it. Also a sign to say the boat is alarmed. No trouble since then. No longer leave a full toolbox on the boat either.
  15. Hi Kevin, 3M make some good outdoor quality tapes. There are various types depending on whether you need stretch, strength or self amalgamating properties. I suggest visiting an electrical wholesaler as they will carry the professional quality products and should be able to advise on which one to use. Be prepared to pay a bit more than your standard insulating tape from the local hardware shop.
