I recommend against purchasing the vessel. I had a similar experience on an Endeavour I was considering. The broker said that water had been found in the crankcase because the mixing elbow needed to be replaced. I asked what had been done to correct the problem and was told it did not affect the performance of the engine, so they were going to let the purchaser deal with it! They had been running the engine to motor the boat around the marina and on a test sail. Unbelievable! I cannot believe a truly professional broker would have taken that attitude.
