A GREAT boat! I have sold a few of the 1990's sabreline 36 downeast style express cruisers- super nice boats and really, really nice lines and workmanship. All engines have their good and bad, including both Cats and DD's.
There is an absolute cherry one in Houston,Tx area. It just recently went under contract. Cummins 6BTs. You might keep an eye on it to make sure it goes. I think it is under contract for 105k...which is a steal . Anyway, check it out.
