I change mine once a year.
I hate supprises, they come at the worst time.
I say when I change the damn thing not the engine.
I throw the old one away and buy a new spare and gaskets just incase.
I have an outboard and cannot even imagine hauling it aboard and pulling the lower end to change it.
Right after the new year it comes apart and gets s full tune up regard less of run time. It always starts on the second pull when cold and the first when warm.
I do a couple of dozen engines in January from my little one to up to the new v-6s for my motorcycle clients.
