I've just bought a 1999 chaparral sunesta 232 with a merc 5.0 w/alpha 1 2nd generation outdrive. My question is how much oil should the outdrive be using? The boat has 200 hours on it. When I picked the boat up, the outdrive reservoir was full to the line and after a few days of use, it's dropped 1/4". Is this normal? i/o's are new to me. Thanks in advanced. This is the greastest forum on the web!
