I have an old Jonson 9.9 mq 3. I think it was made in 1967. Motor is in great shape and has only been used in fresh water. After 10 years of sitting and a little prep it started on second pull. I have changed the lower drive oil, replaced the plugs and water seems to be circulating good...anything else I should be worried about? I am taking motor to FL and putting on a Geenoe for occasional use. If motor is flushed with fresh water after each use will this be sufficient?
