I just bought a 95 bayliner capri 2050 that runs like an absolute top except it leaks a few ounces of drive unit lube into the bilge in a few hours of run time. The previous owner had it in to Pro power sports and marine in Ramsey, Miinnesota last November and had a new shaft seal kit put in to solve this issue. He has all receipts. After the repair he never put the boat in the water until I test drove it 2 weeks ago. After my first hour on the water the bilge had 5 gallons of water in it as they had not hooked up the speedo tube. My questions are: Is a small amount of leakage normal? Can I show them the receipt from last November, from the prior owner, and get any results? I realize other issues may be the cause of another seal failure, but the price I paid was a little higher due to the confidence of having this maintenance done on it. This is what I would consider a good dealer. What do you think.
