Haven't had any diesel mechanic
horror stories....yet.. haven't hired any...yet!
I belive the captain/owner should have a good working and hands on knowlege of their motor
. Not to the tear it down and rebuild
level.. but, at minimum how it works.. being able to, and having the tools, spares, and supplies, on board to, service fuel filter
, impeller..etc to quickly troubleshoot a problem, on the water
, far from home. Having a mechanic
do EVERYTHING is counter-intuitive..to me anyway.
I have spent on our boat was taking a Mack Boring 3 day Diesel
mechanic class. Got to work on actual motors (I got lucky and got to work on an identical motor
I own).. we took apart the filters, belts, fuel
injectors, adjust valves, etc and put it back together. Learned coutless tricks.. most important to break open the high pressure fuel
injector lines when hand cranking the motor with a breaker bar (say to adjust the valves)..otherwise the motor may start!
The stories the instructor was telling us about customer horror stories was amazing... customer always blaming the mechanic for whatever went wrong.. but not telling the mechanic they made an attempt and couldn't fix it..or had a lack of maintenance
and many times making it worse! I would bet there are more CUSTOMER horror stories than mechanic horror stories.
After taking the class, I want to know what my boat yard was doing when they quoted me $600 to winterize the motor and $500 to commission it in the spring!
I think the owner should get down and dirty with your motor .. frequently .. be one with your motor!
Plus the $$ you save you can put away for when something actually goes wrong and you need to actually hire a mechanic for a problem that is out of the scope
of a DIY'er.
