can anyone tell me the difference?

The "high thrust" motors typically have larger lower units, higher gear
ratios, and different props than "standard" outboards , but I believe
the powerheads are the same in both types.

Yes, that was the case with the Mercury 60 Big Foot that came with the
16 and a half foot Legend bow rider I owned a few years ago. They
claimed it had the same lower end as the 90 and had a special larger
high thrust propeller. I believe it was originally popular for pontoon boats.

"They claimed"? That's hilarious! Only you buy boats on a salesman's
word and look what that got you. The reason they are popular for
pontoon boats is that they can move a heavier load, at slow speed, more
efficiently. They were never designed for the hull style, and weight,
of the POS Legend you wasted your money on. They probably had a Bigfoot
laying around at the dealership and sold it to the first dip**** to walk
in. That salesman probably got a nice commission for unloading that
from their inventory.

Boy...y'all are getting more ditzy by the day.
The boat manufacturer offered the 60 Big foot as an upgrade from the base 40 hp outboard.
Y'all should keep your pie hole shut unless you know what you're blathering about.



A 60 hp would be an upgrade if in a standard motor. The Big Foot and my
Yamaha T-8 high thrust are for displacement hulls. My T-8 has the lower
end of a 25 horse for the strength and a lower gear ratio, and a larger
propeller. Moves lots of water, but at a slower speed. Would figure the
same for the Big Foot. Designed for displacement hulls.
My T-8 has a 11.75” diameter 5 pitch propeller as opposed to a standard 8
hp of 8.5” and 9.75 pitch. Will move my boat a max of about 6 mph, which
is hull speed, and will troll at less than 1 mph at idle. When I used my
Mariner 15hp 2 stroke as a kicker, I could get about 4 mph max and a lot of
churned up water. Would troll, but at a higher rpm.
