I was trying to get an idea on the cost to repower. When i look on the internet the YanMar 350 goes for $17,000, but when i contacted a local YanMar dealer they said the engine is $35,000. Why the huge difference in cost? Also on a different subject I discovered that my dipstick was missing from my port transmission. I found the top part of the plastic dipstick in my bilge, how could this have happened? I had my oil changed 4 months ago maybe the technician left it out and layed it on my exhaust manifolds or did my tranny take a crap.
