"How much better are Turbine Motors now?"
Boat Friendly Turbines are propshaft Turbines. These were
designed to run in Helicopters and the Technology dates

The consumption of fuel at rated horsepower of a t53 l13b
is approx 180gph. Turbines Idle at 46 percent.

"I know they cost a bunch to fix if you have to pay for it but I do all my work myself and Have two guys working for me now that were in the army and thats all they did was fix turbine engines"
Tell your Army friends to go back to the Army
You dont have to fix turbines.
Dont suck any Seaguls threw them and ya wont have to worry.
Its called F. O. D.
The other killer is Temperture. 75% of the air being fed threw
the turbine is used for cooling and seal pressure.
The other 25% is used to create the power.
Keep them cool and watch your pyros.
