refering to advances in electronics, and that you can now buy a lap top for 300 bucks, not a radar.
My previous boat, a 34' CHB trawler had a head in the bucket Furuno 32 mile radar, looked like something out of flash gordon, and was complicated to operate, you had to let your eyes adjust from the 'bucket" to the day or night , when i bought the boat in 1996, the antiquated radar was only 14 years old, I put a new raytheon 16 mile on the boat, was night and day in technology, and now, that raytheon looks like a dinasour with the CRT screen.
I now have a Furuno that was on the boat when I bought it, while it has an LCD diplay, it's nothing like is available today with the NAVNET technology.
that ol' 120 Ford Lehman was a great engine, 1000 lbs, 120 hp and the size of a buick, the new 300 +- HP cummins are smaller, more efficient, smooth and quiet and don't smoke, they self bleed and self diagnose, if you have ever bled the air from a lehman injector pump in rolling seas, you'll appreciate this feature. The lehman was a bullet proof 10,000 hour engine if cared for, but the technology in todays diesels are far superior to the old truck / tractor engine that the lehman was based on, it was truly a great engine, but I would not put them in a new boat / machine today
The weight of the engine oil is based todays machining tolerences that were not possible 20 years ago, again technology, the viscosity will not make an engine more efficient, especially an older engine designed for a heavier oil, in fact it may make an old engine less efficient if the lighter oil does not help the comprssion rings seal, and heavier weight oil can easily make a new enigne less efficient, the tolerences within new engines are so tight now that the engine must work harder when working against a higher viscosity oil, think grease and machine oil, you wouldn't put 20-50 in the head of your vertical mill, as it would cause heat and drag and eventually wear out the quill bearings, kind of the same theory in a modern engine (turbine oil?)
I have a 2010 F150, 5.4 with 5,000 miles on it, the twin to it had the oil changed recently and delo 15-40 was used mistakenly, (we buy it 500 gallons at a time) and the mechanic used the wrong depenser, the driver complained that it acted doggy and the avg mpg indicator went to 13-14 mpg, i get about 16 -17 on mine all the time. they changed the oil and put in 5-20, and the mialge came back
and yes, my 03 yukon, 2 MPG penalty for incorrect oil
06 Dodge Ram, 2 mpg penalty for incorrect oil
SAE oil specs must be met to keep the warranty in effect, but so must the weight. and now with diesel emission regulations, ULS diesels, DPF and exhaust fluids, you MUST use a low ash oil, ULSD and the correct EF, or, you guessed it, void the emission system warranty if a catastrophic failure is traced to incorrect fuel, oil or EF,
Trade shows, yes sales shows, and you can spot a huckster from a mile away, especially if you are talking small town fairs, However, attend a few of these, it'll change your mind on trade shows and the technology available,
SEMA, CONEXPO, NTEA, Powder and Bulk, ASTA and a host of west coast boat shows, (for personal fun)
silicone, technology,
all glues and sealants have everything to do with technology, sailors used to seal wood planks with pitch, craftsmen performing wood working projects used glues ;similar to elmers and contractors sealed with acrlyic caulking,, now there are products that will adhere and cure underwater, tapes that will hold car parts together, (trim panels) gorilla glue, silicone, JB weld, hell, duct tape, heck we use a metal tape (FAA approved) to repair the leading edges on helo blades to keep it in service until a permanent repair can be made.
I'd bet that if you have a recent year vehicle, that the valve cover and oil pan gaskets are silcone or some version of silicone,
Technology is the continual advancement in any product that makes it better .
Sticking your head in the sand and ignoring technolgy becuase your reasoning is that this is the way I have always done it, so it must be right, guarantees that technology and your competition will pass you by.
silicone today is not the crap we used to use to seal the shower, is cures better, has better adhesion, creates a seal that is impervious to most chemicals and soaps we use daliy on our boats and equipment and it is a good product. however it is not the catch all end all of sealants, none are.
I do not know what kind of sealant that was used originally on the trojan rails bases, but it was dried out, cracked or missing, and i'll bet the boat had leaked for years, I just feel lucky that it does not appear to have caused core damage, one blessing of living in an arid region and salt water environment (wood preservative)
I grew up on the Mississippi,(dodging barges in a alumacraft with a 9.9 honda) boated and fished the lakes of Minnesota, Wisconsin and Oklahoma, bought my first boat at 13, bought my first car at 15, and with the thousands of projects to cars, boats, planes and homes I know one thing for sure, I learn something new everyday, and that guy you think ain't so smart - has probably forgotten more things than I'll ever learn.

This is a 300 HP Isuzu enigne that was in our Hitachi 450Z excavator / drill we repowered it with a new TIER 3 Cummins 325 HP and about 1300 ft lb torque, the Isuzu is about 1050 ftlbs. the Cummins is 1300 lbs lighter than the Isuzu , we had to ad counter weight to the machine to keep the balance correct on the rotation bearing.
