I have a 25hp mercury outboard that has been sitting for about 10 years. It was serviced every year prior to that. I know that I will need to rebuild the carb and change the lower end oil but what else should I do before attempting to start using it again?

Thanks for the info. Also how much oil do I mix with the fuel? I inherited the boat and I don't know much about it.

Do you have any idea what year it is? Post the model and serial number, if you can.<br /><br />There should be a plate on the clamp bracket.

I would also replace the thermostats if it has em.

Put some 2 cycle oil in the cylinders and turn it over by hand before trying to start it...
