Hi, <br /><br />I all new to the boating world and I have just bought a 23 foot cobia and put a brand new mercury 200 outboard on it. In order to keep the waranty valid I need to get the 20, 50, and 100 hour services down. Can someone tell me if this is able to be done while the boat is on water or does it have to be hauled?<br /><br />Cheers
