Better than Best
When I first started sailing boats with an inboard diesel, I didn't know squat about their maintenance. An embarassing situation with an overheat when my father-in-law was on board strengthened my resolve to get educated. I did buy Marine Diesel Engines by Nigel Calder which I highly recommend (I also highly recommend his Boatowner's Mechanical and Electrical book).I wanted to take a class, but there were none locally so I found a local mechanic who was both good at what he did and also a good teacher. I paid him his normal fee and in half a day's time he took me through tensioning belts, changing fuel filters, bleeding fuel lines, swapping out impellers, etc. etc. Factoring in the cost of travel, it turned out cheaper than a class, AND it was done on my boat and my engine so I knew just where everything was and how to do it.I've done all my own engine maintenance on boats since then and fixed problems that develop while out cruising which is really critical.Hope this helps.Gary WyngardenS/V Wanderlust h37.5
