Portable stainless outboard motor test tank

Portable stainless outboard test tank. I have successfully run my Yamaha 30HP which weighs 130lbs and has a 20" leg. Has water ports to fill/shut off including lower drain & black hose to keep water consistent while running the motor. Frame 2 x 6 construction, easy assemble and easy take down.
