I've never figured out why boaters are SO enthralled with diesels
lugging along at 1200 RPM that are made for 3600-4000 RPM by the
Japanese geniuses.

Amen! I was told early on by a diesel mechanic that it was best to run
my little Yanmar diesel at higher rpms. My boat isn't in the water yet
but I think I usually run mine between 3200 & 3400 rpm. That gives me
a little left at the top if/when I need it. I've been doing this for
18 years & I've had zero problems.

Luggin' a 1GM sure is hard on motor mounts and the hull under them....

I think the prop should be small enough to over-rev the 1GM by 5% without
creating a huge cloud of lampblack.....

A too-big prop isn't going to create more power. Maybe that's what they
think. A 3GM adds more power....(c;
