I have a 2001 4.3L EFI Merc w/ Alpha I Gen II drive with 140 hours.<br /><br />Supposing regular maintenance (engine oil & filter, drive oil, winterizing, gimbal, drive pivot, & coupler greasing, etc.), how long can one expect to run such a package without a repair outside of this type of basic maintenance? 1000 hours? 2000 hours? Is it hour dependant or more number of year dependant?<br /><br />Let's assume that there is no catastrophic "accidents", "defects", or "stupidity" to bring on a repair.<br /><br />For example:<br /><br />How long could I expect to get out of:<br /><br />-gimbal<br />-ujoints (prelubed type)<br />-drive gears<br />-drive seals<br />-coupler<br />-heads<br />-engine<br />-fuel system<br />-bolt-ons like PS, alternator, starter, etc.<br /><br />I'm new to this stuff and was wondering what I should prepare for. I know "it varies," but give me some general ideas.<br /><br />Thanks!
