Lower Unit Problem...

    Sunday I decided to get the boat ready. (14' starcraft w/ a 9.9) I decided to change the lower unit oil, 1st time since I just bought the boat used last year. Seemed like an easy enough job However when I removed the top screw it didn't want to come out. When it did I figured out why, the screw was cross threaded. :mad: Now it won't tighten. :( Do I need to take it to a marina, or can I just tap out the hole and use a larger screw?

    Any advise welcome.
