The shipyard I've been working at for the last 15 years was recently absorbed by a much larger company and they brought with them a 1994 Donzi 54 with 1100 hp 12V92s. I get to babysit the boat
and really it's not that bad of a rig. My problem may end up being the heat exchangers if they are
like all the other DD's I have experience with. Here in southeast Alaska in the spring there is an
awful lot of spruce needles in the water and they plug up the sea strainers pretty quickly and
some of the little buggers get through the .070" holes and eventually foul the cores. I clean my
cores (8V53)every 3 years or so. The problem with the Donzi is he only has external screens (no basket strainers) and the holes are way bigger than a regular basket strainer. Is this going to be a maintenance nightmare for me or are these cores more forgiving than the DD wafer type I'm used to?
