  1. Yeah, ive heard that as well - unfortunately i don't have any and the white vinegar alternative isn't doing much. I really dont want to take a trip to Bunnings hence I'll try poking it clean with some wire and see how it goes.
  2. Quick update on this since a few of you are interested. I finally got down to the boat last weekend and after tearing apart the raw water cooling system, i discovered a VERY blocked up water injection mixer (see pic) that Im 99% sure is the problem. The raw water intake side of the mixer (not exhaust) is completely gunked up and will be cleaned out this week and re installed. I suspect the raw water was under such pressure due to the blockage it was forcing its way back through the rubber connector (and clamp) that seals the heat exchanger, and into the fresh water system. (not
  3. I had my boat sign-written with Vinyl lettering about 10 years ago - its still lookin great. My counter stern faces north in the marina and cops the sun all day. Dark blue lettering on silver/grey.
  4. No not yet. Life keeps getting in the way. Im hoping to pop down this weekend and at least start the engine for a few minutes and take a further look. The wife and daughter are heading overseas next school hols so I'll attack it in anger then
  5. I'm not surprised and I bet a majority of it is due to inefficient, unproductive, bureaucratic red-tape.
  6. Many thanks all for the additional input - its going to be interesting to figure this one out! Touching on your comment IT "AND loss of water from header tank" whilst its loosing water from the header tank, the level doesn't seem to decrease?!?!, hence im thinking raw water is getting into the coolant as pressure builds with the revs . . . maybe Anyway, I'll start with a new cap, check impeller, then disassemble, clean, inspect and reassemble the the header tanks and exchanger to the exhaust mixer and see what reveals itself, if anything. Ah the joys.
  7. Thats exactly what some others are suggesting on another forum as someone else had the same issue. A breach somewhere in the raw water/fresh/exhaust system is causing back pressure when the revs increase. First plan of attack will be to checkout the heat exchanger and raw-water exhaust mixer and their connections
  8. Many thanks everyone for the input - much appreciated! It sound like a methodical approach starting at the cap, impeller, then check and clean the heat exchanger, check thermostat and then exhaust mixer will be the plan - fingers crossed. As an FYI, the engine was rebuilt less than 100 hours ago but has had very little over the past few years hence I'm pretty comfortable its not a head gasket, also, the water in the heat exchanger is perfectly clean, but we will see. . . . Lets hope i havent killed the engine for the second time Thanks again, I'll report back once i find so
  9. I thought I'd try the collective wisdom here before i start down the rabbit hole of diesel engine trouble-shooting. Over the weekend and while on the marina berth I started the above engine, and after a short period in idle, i upped the revs (in load) and headed down below. Only to discover the overflow pipe beside the filler cap was dumping green (antifreeze) water in the bilge at a rabid rate, and hence i shut it down! After a minute or two, i opened the filler cap (small amount of pressure) and, expecting the exchanger tank water to be empty or hot, stuck my finger in to discover it
  10. What about a decent tablet in a case with Navionics?
  11. I thought this post was about jet skis
  12. Have you tried overseas VP parts suppliers? I've used www.keypart.co.uk for a recent VP rebuild and there parts were 1/3 the price of the local guys and delivery was faster.
  13. I cant speak for those particular boats, but in my experience sizing comes down the the specific marina and its management. My boat is 12.8m OA and some marinas will let m on a 12m berth, others (Westhaven, Opua for example) will insist i take a 14m. It would pay to get the exact length OA and call the marina
  14. A drain at the bottom.
  15. I did this several years ago and it was GST and duty excempt. My documentation on place and time of manufacture was pretty loose and customs had no issue with it
  16. I have the same engine and the buzzer sounds on cold idle until I give it a few revs - I should probably adjust my idle speed
  17. I agree, Ive had a great run with my VolvoPenta and whilst the local parts are pricey, its now very easy to buy offshore at a fraction of the price I havent used parts4engines, but bought my MD2030 rebuild parts from www.keypart.co.uk and highly recommend them for service and price.
  18. I'm just wondering if marine salvage laws apply to a beached digger? Hypothetically speaking, if you rowed over to it, tied a line to it, could you call it yours?
  19. Your wife has good taste. Me likey too
  20. Try these guys www.keypart.com Their OEM VolvoPenta parts are a fraction of the local price and delivery is generally faster as well!
  21. +1 Mitchells in Silverdale had a great range of teak trim bits
  22. There was a very mixed fleet racing out of CCYC at Hobsonville marina most Wednesday nights over summer. Mark Foy starts and relaxed racing could be a good starting point?
  23. DIY. You can buy flexible LPG pipe and crimp it on myself.
  24. Very nice Abel S. Any guesstimate on final weight?
  25. Yup, for all its faults, the interweb is truly brilliant for that type of thing.
