I recently purchased a gently used Honda 9.9 Power Stroke / Four Stroke (looks to be about ten years old but very clean) to push my V222. I purchased it from a friend (actually it was the motor on the boat originally). The boat was free with a $1200 motor lol. That being said, we saved our pennies and purchased the motor this week. It cranks fine, seems to be in great shape. Other than cleaning the carb and maybe changing the plugs what will need to be done to it before splashing? What about the oil in the lower unit? Does that need changed / checked? Since we can't afford another motor we need to make certain we don't screw this one up. Any suggestions or comments are welcome.
