I have two Vacuflush heads, and a few days ago one would not flush.. Motor would not turn on. I suspected the vacuum pressure switch was the most likely culrprit. Sometimes there is an advantage to having two of something. It wasn't practical to swap the entire switch assembly, but I was able...

I have just replaced engine and oil cooler anodes. They all look similar, with a crusty substance that I assume is a hydrated zinc oxide or similar substance. One of the cooler anodes, which are about 1cm in diameter, had material dislodged on removal. Scraping that with the end of a...

News reports on Sydney's Emerald class generation 2 catamaran ferries are intriguing I think. The ferries are designed for ~400 pax and 26kn. Installed were a pair of Yanmar 6AYEM-GT engines. These are rated at 900HP (light duty) and around 1000HP (pleasure). One failed...

First up the mea culpa: I have not been very diligent in flushing the outboard with fresh water after operating it in the ocean. So the tell-tale is down to a dribble. The over heat alarm has gone off. So, i changed the impeller even though the old one looked perfectly fine. I changed the...

I log each trip I make, and record distance and fuel consumption. For interest I've just made a histogram of the data. The boat is an Ocean Alexander 50 Mk 1, and with typical fuel/water it has a displacement of around 28 tonnes. Power is a pair of Tier II John Deere 6068 TFM75, 201HP...

Sad news posted on Moreton Bay Cruisers facebook group - Dave passed away overnight. He came into my home marina a couple of months ago to 'sort out some things', and I understand an operation was part of it. At time provocative, he did have a lot of knowledge and I'm sure many of us will miss...

While it suits the agenda of quite a few people and headline writers in the press to shout doom & gloom, death of the Great Barrier Reef isn't going to happen anytime soon. The Government's Long Term Monitoring program reports annually. Below is from the most recent report, and here is the...

Crew of 5. Memo to superyacht owners: hire someone who knows how to drive. Ability to look out of windows desirable https://www.dailymail.co.uk/news/article-11188261/James-Bond-themed-superyacht-called-007-SINKS-yards-Greek-beach-running-aground.html

My old Icom M127 works perfectly, but the screen has reached the point where it is very difficult to see what channel you are on. I found a business in Florida that offers a repair service, but sending to FL from Australia isn't practical. I then found a August 2011 post on sister forum CF...

Sure, its not your average yacht. But it can make "trawler speeds" and has reasonable windows. Thin end of the wedge? Dock Queens next?

I am in the process of removing my Excel #8 anchor and 10mm chain from the boat and likely getting them re-galvanised. Due to flooding the River is closed for recreational purposes so its a convenient time to do it. For the anchor, its a given to re-galv. But for the chain there are other...

Last haulout was in early 2018, at which time I had Jotun SeaVictor 50 applied as the antifoul. Previously I had used International Micron Extra, which performed poorly, growing lots of slime along the waterline and heavy crap over the rest of the hull within a year. I had checked the Jotun...

There have been a few threads on stabilisation discussing passive options (batwings, rolling chocks, paravanes) for reducing roll underway, and many will also reduce rolling at anchor. But there are also some simple devices for reducing roll at anchor only, that cannot be used underway. One...

I did an extensive upgrade on my boat in 2012-2013. Re-power, Naiad's, new fuel tanks, basically rewired, new switch panels and more. I've had trouble free cruising for over 2000 hours on the engines, which was the objective of doing everything at once at that time. The only stuff I've done...

I was intending to reply in a thread in the Marlow-Mainship forum that was discussing 'Change Electric Stove, Install Gas Stove'. However, that thread drifted off topic (badly), and many regular & knowledgable contributors ceased posting. It was basically trashed. A reminder - if you see that...

I am looking to replace my fresh water pump in the near future. I have two heads/showers, a galley sink and icemaker as the users. My current pump is 10 GPM and 67 psi max. I'm not sure that I really need that flowrate as have never needed to run both showers at once. What kind of flow...

My old house battery bank used 6 x front terminal 12V batteries. They were connected to positive and negative busbars (Blue Sea 600A rated), with some variation in cable lengths but they were relatively short or very short. My new house bank is going to be 10 x top terminal batteries, and will...

I only learnt to play poker as a Uni student in the early 1970's, too late for the poker game that is referred to in the Island's history. Of course I wouldn't have been able to 'ante up' for a seat at the table anyway...

Well, its no trawler but still looks pretty nice. And the price could be a great deal! https://yachthub.com/list/boats-for-sale/used/power-boats/princess-p57/248370 But. Its been sitting in a shed for 8 years. Undercover but in a hot humid climate. Apparently it was a Police seizure...

The attached graph is showing good progress in regards to declining new cases in Australia. However, lockdown conditions continue to be tightened, with authorities fearing outbreak clusters around the Easter holiday period in particular. Conditions are set at State level with some regions...

I seem to recall discussions from time to time regarding the frequency of raw water pump impeller changes, but could not readily locate a thread on it. For my starboard engine I have changed the raw water pump at 2 or 3 year intervals due to failed seals, and thus changed the impeller...

The pic was taken by a Mr Clarke Espie in the Cromarty wetlands south of Townsville. The news article unfortunately requires a subscription or payment, and has a couple more pic and a little more info...

The news item is brief, and I'm not sure of the boat brand and size. But it seems likely it was a twin engined boat on the plane. I don't see how else the props and struts would be ripped off after hitting a rope. Maybe there will be more detailed reports once the guys get off the P&O cruise...

So, my Torrid Hot water tank has developed a leak. I have started to remove connections to it and will remove it (hopefully) in the next few days. It was installed then piping and other stuff placed in front of it, so getting it out is going to be a little tricky. I see in the Torrid...

I have been using Cmap charts most of the last 6 years on a Time Zero display, and am generally happy with them. I also have their satellite photos, and although they are OK for the coast they are hit or miss for the islands and outer reef areas, and not particularly good resolution. Google...
