Selling a used 9.9 2006 Yamaha 4 stroke powerhead. This is the model with the spin on motorbike style oil filter. The engine had no issues and used no oil. I took the head off just to check for any corrosion or salt build up and to show those looking at it what they are getting. It comes with a new head gasket. It can be viewed with the head off and I will resemble and torque the head for the buyer. This engine works for both the high thrust or regular gear case models.
