So I have an outboard that hasn't ran for 10 years . Guessing it will need a carb kit and possibly seals . That aside , I want to know from anyone who's had success with this . I've been told before , if you want to try turning a dormant motor over , to add some form of lubricant in the cylinders , let it sit for a while and then try to turn it over . But , I'm wondering what lube is best ( it's a 70hp. Evinrude 2 stroke ). I've herd several thoughts , but I just like to hear from either your thoughts , if what you tried worked . And yes the motor was fogged , but I'm sure that would have little affect now . So 2stroke oil , 3 in 1 oil , WD 40 ( think that stuff is dicey ), a seafoam product or Lucas product , how much add into the cylinder ? How long do you let it sit before trying . There is this new stuff at TSC called Mechanic in a bottle , that says it will renew seal life and a bunch of other stuff which may or may not be a sales pitch . Any experience with that stuff ? Was thinking of going up today to grab something . Just not sure what . And I'm guessing this is a one shot deal , so would it just be better served having somebody taking the head off and quoting a price ?
