It's a 1977 Glastron w/ the Volvo outdrive.<br /><br />Tell me if I'm wrong: <br /><br /><br />1.) unscrew lower screw under prop to drain.<br />2.) replace<br />3.) unscrew upper screw<br />4.) fill w/ 30 wt.<br />5.) replace<br />6.) do all this with motor level.<br /><br />is that it? what am I missing???????<br /><br />thanks - <br />Ben
