    This is a bit of a worry then. The low hour engine on this yacht was one of the drawcards for me, but I didn't even consider it being underpowered since it was recently replaced. I'm not sure if I could afford a new one on top of everything else I'd require. I've had a look into this and the rule of thumb is 4hp per tonne and this is 3.33hp/tonne unloaded.

    Can this be a safety concern if you're battling wind/currents to get to safety or is it more of a speed preference thing where you would just be painfully slow?

    I'd be more inclined to go with the 1hp/ft rule. I have a 32ft over all 24ft waterline with 4 tonne displacement. I have a 3GM30 27hp. I couldn't imagine life with 16hp.

  2. It looks like power supply quality, as IT suggested. Sometimes, when the voltage drops very slowly to a point below the digital electronics logic thresholds, they will lock up. Similarly with a quick dip.

    Can you connect it to a known good battery, on its own, and see how it holds up?

  3. If it's still getting power while it's dead, have you tried cycling the power to see if it comes back up, or still waits 15mins? If you have to wait, it may be something overheating and needs the time to cool.

    curious to know which marina asked you this?

    There is a concerning trend of the marinas inventing all sort of rules that are not actually legal requirements. They are correct to ask for an EWOF because that is the law and they are responsible for you connecting to the power supply, but a gas certificate?

    This will be Lyttelton. It's in their contract. They had a push on EWOFs and tagged extension leads recently, but they don't seem to be pushing the gas certification part yet.

  5. Are you wanting to clamp a hose, or are you looking for clamps hold a pipe? What you have described sounds like a tube clamp, which is used to hold stainless tube in dairy plants and the like.

  6. If all you are wanting is to ensure your batteries are kept charged by plugging in a charger and leaving it unattended, don't do it. You will need an EWOF and that will cost you $$$. The subject of EWOFs has been covered extensively in this form, just do a search.

     

    Your money would be better spent on solar, which will charge your batteries wherever you are and is more fun to set up. Also, get a tagged extension lead which you can only use on the boat while it is attended.

     

    That's just my opinion and will get other options too.

  7. If it was exported after construction, so no tax was paid on the original purchase, tax would be due.

    If the original purchase was in NZ, tax would have been paid, so none is due.

    My understanding is that's how it works in the EU so NZ may be the same, otherwise they're double dipping and we all know the government would never do that to us.

  8. I have a marinised Shibaura S753 [Perkins 104-10, Perkins Perama M30, Volvo MD2030, Caterpillar 3003, ford 1220 and there are lots more places this engine has been used]. It is a solid little engine that has found its way into lots of equipment, machinery and tractors, so parts are no problem at reasonable prices or full rebuild kits for that matter.

    It has unknown hours or history. It does start easy if glow plugs are heated from cold or if warm no issue at all, no smoke under load either. But I would just prefer the piece of mind of a semi blank slate on the history of a boat engine.

     

    I am more than capable of removing and installing an engine either existing or new. I would not rebuild one myself, that is beyond my skill level.

     

    So what are some pros and cons? What have been your experiences? Suggestions? Recommended mechanics?

     

    I am really struggling to make up my mind.

    Starts well and no smoke. Sounds good to me. Maybe get a compression leak down test and oil analysis and if all good, as Maté said, go sailing.
