  1. Hi. My boat is a 47 year old Cav 32. Like most Cav 32s of the time, the engine was positioned forward facing, and transmission went through a remote Viking vee-drive, changed direction and went under the engine then through the hull. I am installing a vee-drive to replace the original Viking vee-drive and I need to rebuild the footings. Problem is that I cannot tell for certain what the angle is of the propeller shaft where it goes through the hull. I can't actually get a clinometer onto the propellor shaft becuse of all the other things in the way, but I think it is about 8 degrees, where as
  2. Hi Everyone An update! Andrew Connelly is the man! I very indebted to this man for helping me. His old Vee-drive is a beaut! So, now I've got to fit it. One question: does anyone know the angle of the propeller shaft on an old Cav 32? There's a bulkhead preventing me from getting an accurate reading. I think may 8 degrees. Does anyone know? Cheers
  3. UPDATE: I took the old v-drive to Moon Engines who took it to their specialist welder. The welder thinks that there is little chance of the casings surviving the weld job. So that means that Plan A is off the table. Plan B is to chase up Andrew Connelly's offer of using the second v-drive that he took out of his boat. I am having problems reaching him. If any of you know Andrew, can you help me contact him? I have already sent him a direct message with my phone number in it.
  4. Hello Everyone I just wanted to thank everyone for their helpfuil comments here. I have decided to go with a repair of the old v-drive. The guys at Moon Engines advisedthat there was a half chance that new bolt holes could be welded to the aluminium casings. It's a tricky job and might cause the casings to warp and become useless but it was worth giving it a try. Meanwhile, Andrew Connelly has a spare v-drive and that could be an excellent plan B. Plan C is to purchase the Argo V-drive new from Ozzie for around $2000 NZD. Thanks again for everyone's help. It's really appreciated. Mar
  5. Hi Andrew, thanks for that! I am very interested in your V-Drive. Maybe I could chat to you? I will DM you. I have got a plan that might not work out, so your v-drive could do the trick.

  7. I should add, that my old unit is not strictly speaking a v-drive. It's a parallel system with a 1:1 ratio. Much simpler than the Argo V-Drives.
  8. I just spoke to "Jim S" who offered his brother's foundry service, and Jim himself runs a tooling workshop. We had a great conversation about making new moulded casings and then reassembling the whole unit. It's an attractive idea because I would get something that fits into the current space and wouldn't need to reshape the interior. Big should out to him. I'm still in conversations with Moon Engines and with Argo in Ozz. Slow progress. Stay tuned.
  9. That's awesome Fish. This is the kind of info I need. Main focus for now is the v-drive.
  10. Awesome, Syohana! You and Wild Violet are thinking along the same lines. I will put the to Moon Engines. Do you know of a workshop that can make this sort of stuff?
  11. I wasn't ware of the Python Drive so thanks for that. The boat was using universal joints and a "spider joint" to account for alignment issues. Thatn worked okay.
  12. Hi Everyone A couple of you aqsked for photos of the problem. Here's two phiotos showing the corroded / broken threaded bindings on the v-drive case. You can see that the unit is generally corroded. Sad situation that it was still working fine inside despite the issues on the outside. In another update, the guys at Moon Engines advised replacement. But I'm gonna chat to them again about a simpler cog and belt system and ge their reaction. I have really appreciated everyone's comments and advice. I will let you know how things develop. Happy sailing. Martin
  13. Hi Wild Violet This is a really exciting idea and it's great to hear someone has actually done it. I'll go back to Moon Engines and ask the if they could build something like that. One advantage of a motorbike belt system is that the lubrication requirements may be much simpler and the whole thing can be maintained by me from time to time. Do you know how I could contact the "bloke on a cav"? Martin
  14. You may have hit the nail on the head here. The initial problem was that the thrust bearing broke, so the propellor shaft went backwards about 70mm when we put the engine into reverse (to lay anchor). Paddy (of Paddy Marine) says he does a "complete job" and won't touch it unless the whole drive train is tested. That includes the v-drive. When he took the v-drive to be tested (not sure by whom) they said that because two of the threaded bolt-holes were broken, that they would not be able to seal the unit after inspection.
  15. Thanks for the tip. I contacted Bill. He says he has a "kanzaki". I'll jhave to look it up on Google.
