>There is NO way replacing the engine mounts for both engines should be more than about $1K, $1.5K TOPS! It takes two people a day to a day and a half to unhook the engines from the shafts, install the jacking braces, unfasten the old mounts, jack up each engine, install the new mounts, let the engines down, and realign the shafts. With shop rates of about $80 an hour, that works out to about $2,000 in labor. Given my experience with removing engines from vehicles, I have no quarrel with the amount of time this very experienced and reputable diesel shop says it's going to take. Working in the confines of a GB36 engine room with two big Lehmans and a large Onan generator is not a fast process. The mounts are $80-$90 apiece, and we need eight of them, so there's about $1,000 in parts with tax. So if everything goes according to plan, the cost should be about $3,000. Now when is the last time anything having to do with a boat (or plane) went according to plan? We have gotten into the habit of taking the "best case" estimate and multiplying it times 1.5 and 2 to get a realistic idea of what the end cost envelope will be. We have NEVER been wrong in this in five years of owning the boat. We've never had poor work done on the boat, and we've never had to have a shop do something again. But the nature of boats is such that something always seems to "crop up" during the job. So using our so-far very proven formula, it will cost between $4,000 and $5,000 to have the mounts replaced on both engines. It will be great if it costs less, but we're not expecting it. ______________________________ C. Marin Faure GB36-403 "La Perouse" Bellingham, Washington
