It's BIG. It's HEAVY. And it *still runs*. It's developed a fuel leak and I think is mixing oil and fuel internally and the manual has what seems to be thousands of parts all working together in it. but *it still runs*, spitting fuel. I really sit there and just admire how well we built things in the good ole days.... And she doesn't have bluetooth. Or a computer. Or nothin, just things geared up just the right way. It's a marvel to me... I've loved learning about how it works. I've gone and looked at new motors, and in comparison they seem impossibly fragile. I've also looked over the latest in electric propulsion... but I cannot imagine an electric motor at this stage of the game surviving 40 years in an aquatic environent. And the best batteries are kind of a fire hazard. I don't know if I'll rebuild this motor or not, as finding a mechanic or shop willing to work on it has been impossible thus far. For the record, the boat has eaten two phones, 1 tablet, one archer C7v2, and a raspberry pi so far. And I needed to switch to VGA from HDMI as the darn cables kept vibrating out. There's a picostation going on the mast at some point, I have some hope that will last a while.

Simon (of dnsmasq) has one of these wonderful boats. I went for a ride a few years ago.
