About a year ago I went to the Mercruiser parts desk to pick up some lube and such at Palm Beach Yacht Center. There was a Midnight Express with 3 hanging off the back and all the lower units were off. This was a boat that looked new, I mean the trim tabs and paint were pristine. I walked up to the mechanic and was like wow, did the guy hit something? He said no, maintenance, we need to put on 3 new lowers. I was like? Really? The mechanic went on to say yeah, we repair these all the time.

I threw up in my mouth and walked away...

What Kool Aid are they drinking over there?

AOC and Kamala must have made it for them:violent-smiley-021:

My business has me dealing with folk in the U.K. and the Netherlands frequently. Make no mistake, these guys are DAMNED intent on the whole 'going green' thing, with various pledges of being "zero emissions" or "carbon free" by XXXX date, usually promoted to be within the next 15 years or less.
Seriously?
For one thing, there simply isn't the infrastructure in place to even begin to accomplish this. The list of why it can't happen within the time frame desired (if ever) goes on and on but it's not popular to denounce the effort. As others have noted, we have similar freaks over here thumping the same drum...Bedpan and Kameltoe, along with AOC, just DREAM of this.
Crazy.

Good luck selling a boat with these now

You know I see nothing wrong with pushing forward on new technologies. If all engineers said no way can’t be done, Elon wouldn’t be where he is at.

I mean who would have thought that you could “fly” a first stage rocket back down and reuse it?

The time table of 15 years sounds a bit aggressive but on the fuel cell side, in the mid 2000’s the car companies were testing them. That may not be as far fetched as we think.

never say never.

I completely agree with your statement. Horsepower from electric motors is not the problem currently, it is only the energy density of the batteries - which is currently only about 1/10th that of gasoline. Once the battery technology advances and the energy density approaches that of gasoline, we will see electric everything - cars, boats and even airplanes. I do hope that everybody goes online and educates themselves to the fact that our ships and trains have been powered by electric motors for decades now, with either diesel motors (trains, commercial ships) or nuclear reactors (military ships, submarines) providing the source of energy to create the electricity to power the electric motors. The first flight of a commercial aircraft has already occurred last year when a converted De Havilland Beaver seaplane with a 750hp electric motor/battery system developed by MagniX flew a short route up in Vancouver, Canada. All electric is coming guys, it's just a matter of time.

I think they were a hard sell before....... Intrepids/HCB might have to rethink their designs with the lesser HP offerings from Yamaha/Mercury. A quad 627 boat (2508 HP) can't be replicated with 6 Yami/Mercs hanging off the transom of a 11-12 ft beam boat.

Thanks Matt, I actually had not seen that yet. A friend of mine told me about it recently, and I just never took the time to research it afterwards. Pretty amazing that they can get 2-3 hours run time out of such an inefficient hull design. I also heard that a guy mounted a Tesla car motor (400hp) on an outboard midsection, with the batteries in the boat. There's also currently a boat in your neighborhood Matt that will make waves in the industry when it is completed, but I'm sworn to secrecy on that one..........

endlessly trying to get it running ( and usually swearing )

I can’t image trying to keep 6 of those running all at once;)
