We cruised slow (2000 -2200 rpm) and extended the service interval to 200 hours on Daydream. Pete at West Coast Marine in Bellingham had put a bin of service parts together for me. It included the stuff he knew I would need, like oil filters and fuel water separators, but he also set me up with a water pump rebuild kit, spark plugs, zincs and some other stuff, since he reasoned, correctly by me, that it would be better to have this stuff with us than to have to sit around days or weeks if it turned out we needed these parts.
I did all the services myself (well, Benton Blalock really showed me the ropes on the first service) except the service in Harbor Springs, MI, where a filter deep down inside the outboard needed to be replaced, and watching the mechanic at Irish Boat Shop do this work, it was apparent I made the right choice to have them do it.
Benton pulled us out on his trailer in North Carolina for the first service. The second service was at Rondout Yacht Basin in Kingston, NY, where I was able to use the Travelift for $150, and the owners went to town to buy the oil for us and disposed of the used oil, so all in all, a very good deal. The third service was at Irish Boat Shop in Harbor Springs, MI, where we also bought a new prop. This was the most expensive but not out of line. I did the final service at Aqua Yacht Harbor on Lake Pickwick right before Yellow Creek and the Tenn-Tom Waterway. I used the Travelift there for $250, and counted myself lucky that they let me use it, because they were very busy there. I used a Mighty Vac fluid extractor and think it worked pretty well. I never changed oil on the water, but could have. As Dr. Bob said, you have to get the boat out of the water to change the lower unit lube.
Jonathan Arthur has done the Loop three times on his CD22 Cruiser Salty, but although we crossed paths a number of times, I never asked him what he was doing for engine service. Likewise, I am not sure what the Burkes or the Aussies who chartered Flint and Leslie Firestone's Venture 26 Grace Full did for service.
I was worred about it at the start, but it really turned out not to be a big hassle!
