A friend did the work for me, but he's clueless about boats.
OB is a '92 Mariner 125.
Thoughts?

Thanks stp. Nothing there about aftermarket superchargers.
Probably just not done, or rare because of practicality.

Found this about the Verado at

*****************
Weight can be saved by supercharging. Let's compare the weigh of some
200-HP outboard motors:

1.7-liter supercharged 200-HP = 510-lbs (Mercury Verado 200)
3.6-liter non-supercharged 200-HP = 580-lbs (Suzuki DF200)
3.4-liter non-supercharged 200-HP = 588-lbs (Honda BF200)

The supercharged motor is 70 to 78-lbs lighter. However, if we move down
just slightly in horsepower to the 150-HP range, the supercharged motor
loses any advantage, and instead shows an 32- to 36-lb disadvantage:

1.7-liter supercharged 150-HP = 510-lbs (Mercury Verado 150)
2.9-liter non-supercharged 150-HP = 474-lbs (Suzuki DF150)
2.3-liter non-supercharged 150-HP = 478-lbs (Honda BF150)
*****************

Pretty nice weight savings if I went up to a 200hp.
Looks like the Mercury is the only game in town for supercharged.
Think I'll just stick with the 125 for now, and get my speed gooses from
the Cuda.
