Technology?

Because proven simple stuff works and is easy to maintain and repair...

Take stuffing boxes for instance, many of us prefer old fashion set up with goretex to the drip less high tech PSS or others. A big chunk of bronze is not going to put you out of commission for a week waiting for parts in th bahamas when that fancy talon face seal fails...

Waste system? Why do you want them to be high tech... I want them SIMPLE. We have magnum opus electronic heads on the boat I run and carry a spare board jaut in case. Frankly I ll take a simple pedal Vacuflush instead of relying on a circuit board, an electric water valve, a contact switch, and God knows what.

ANd th list goes on. High tech maybe cool and impressive to folks who don't know much about boats, it maybe easy to throw parts at it if you never stray further than 30 miles from your home dock otherwise simple and proven low tech does the job.

Not really, the Globe impellors flex too much and sometimes don't suck water........another innovation that isn't quite what it's supposed to be. If you do your preventative maintanence you usually don't have issues. It's all this over complicated stuff that causes more issues.

On mots boats the problem is not lack of technology but installation and accessibility.

Since you brought up impellers, I never suddenly lost one. Every time I had to replace one, it gave me plenty of warning with a slightly dryer exhaust on the gennies or slightly higher temp on the mains. And in 25 years i don't think I had to replace more than 5 impellers outside routine maintenance and as long as they were easy to reach and with the right tools it was a 15 minute job. Now I ve been on many boats where the impellers were hard to reach because of poor engine or Genset installation and kept my fingers crossed hoping I would not get a failure.

Agreed. The vanes will float and not pump much. I try to explain this to folks and get long stares.

I improved all the hoses behind some MAN engines a few times. Makes getting to those impellers easier.

Worked on a 53 Hat last week, Those 8v71TI & M clutches offered little room to get to those impellers. I'll be cleaning up that mess this fall.

It's not really the equipment. The ease of getting to it or lack of can dictate the how & when of proper maintenance.
Same on easy or hard to get to shaft logs. It's not the equipment that is outdated, the beauty in some designs just can not be improved.

It's the access; it's the architect who has the problem.

When you have PTOs, Tach cables and multi belts, I have plastic tie wrapped (cable ties) belts to the motor mounts and anything else available to wrap to.
Now if a belt wears of fails, I have a belt ready to go without breaking a PTO coupler or tach cable loose or removing other belts.

Heads arrrrggghhh, on the 2007 Sunseeker I manage the heads were new then they stopped making them around 2009. We bought a dealer demo just to store and have spare parts......But if you look Sealand has around 15 totally different heads now, as do many manufacturers so the luck of finding every dealer stocking spare parts is slim.

I love the headhunter toilets......all they have is one water solenoid to flush and that is it!!!!!!! An electric pushbutton and a water solenoid part that's less than $150 for a spare.......

I remember their first show. The rep was pouring in coins and it never stopped flushing.

YUP, all you need is water pressure and a amp of electric for the solenoid to work, can also plunge them if you need to.....simple, and they work well.....I really like Headhunter. They're a very reputable company in regards to warrantying their products and if you go to their factory in Ft. Laud, they will bend over backwards to help you.

The vaccuuflush are pretty simple, but you need a very long screwdriver or 1/2" dowel to clear blockages at the bottom of the bowl, and also need to change duct bills periodically and once in a long while the vaccuum switch.

I usually get 6 to 8 years out of duckbills, what I like is that they give you plenty of warning when they start having issues and will rarely leave dad in the water. Even if a vac switch fail, you can't still use the head.

But yes, headhunter is a pretty good supplier. I like their Mach 5 pump, although I had one fail in just a year. Replaced right away though. Fluke failures can happen to the best product and that s where good support is key
