Its not crazy loud. well ok next to my 15hp its a 747 but next to the air boat it's quiet as a mouse.
Grab some lights from Harbor Freight like 25 bucks for 100w h-3 halogens. If they break just get more

once you run them you will give up on the hand held lights.
The crank is the trim adjustment. Once on step you just crank it till the prop is half in and half out of the water. Lucky for us not as much sand as mud. Sand is tough no matter what you run unless you got bucks and a airboat. 270lbs the motor is a pig!!!! and she runs at around 4200 RPM
