Direct Drive vs Reduction drive airboats

[twors]

I was wondering if you airboat enthusiasts could help me out... I am looking to buy a 16x8 or 18x8 airboat one has a direct drive prop and the other has a reduction drive... I don't know much about the difference other than I assume you can get more torque out of the reduction drive. Could some one explain the benefits or lack of on the two.... Thanks for the help

The only advantage a direct drive has is price and weight.

Noise, power, HP/ weight of engine system, fuel consumption, number of props available, etc a reduction drive is better.

Lower center of gravity with the reduction gear set up.
