As a former diesel engine marine tech I can really appreciate this engine and his teaching. Now the Ranger Tug, that's another discussion. Lot of information on that but this is not the place.
I think ALL owners should have to take a class on their engines. It is amazing how clueless most folks are. Money are not, it's your responsibility to be educated on your vessel. I've seen it all over all my years. I'm not sating this to jerk. It's like an airplane to some degree. You need to be self sufficient an know how to get yourself out of a jam as best as possible. Some things we just can't help. But for him to have to travel 70 miles to push in a dip stick.... that's messed up.
Unfortunately everyone..for a new boat owner the amount of systems dependant on water cooling is ridiculous, Trucks and buses cool off with AIR. Just food for thought.
This dude is a unicorn. Not to sound racist but when was the last time a black dude work for over 40 years, a mechanic, and just great vocabulary and pleasant body language……
