Hi.<br /> I had outboard boats for 30 years, but just switched to my first I/O.. (23' Caravelle Walk-around with Mercruiser 5.0L 220hp sterndrive).<br /><br />I would like to know what spare parts should I be carrying? Should I buy the Mercruiser brand oil / fluids or can I get them at an auto parts store (any brand suggestions?)<br /><br /> My fuel filter/ water seperator is strange.. you can't see through it to tell when there is water present (all of my outboards always had a see through bowl). My dealer said they aren't allowed on stern drives. True? How do you tell when there is water in it?<br /><br /> I have 10 hours on the engine, and already had to add 1 quart of oil. Is that normal? It was full when the boat was delivered.<br /><br />thanks.. any other tips on maintanace would be appreciated!<br /><br />Al
