Yamaha Outboard Motor 9.9, First check run and gearbox/prop check service

Here I check out a new purchase second-hand Yamaha Ouboard 2 Stroke 9.9 Hp. We look at the starting mechanism and how to avoid problems, check the gearbox oil and replace, check the water pump, check oil seal behind the propeller, and finally start her up.
