I am thinking about buying a 2001 27victory Advantage
496HO for $27,500. When we took it for a ride its got a hell of ratle when the exhaust is switched to the loud position,pulled the dipstick and the oil was black. The owner claims its minor and refuses to have it looked at . His words were "thats why your getting the boat for so cheap" and threw a fit.
$27,500 is alot of money for me.
Am I being overly concerned?

This would concern me.

I would pass ,as he was pissed that you heard it

If your ok with another 5-7K to go thru the motor then go ahead with the deal .....

Walk
Away.

How did it sound when in quiet mode?

usually mechanical engine faliures are more detectable when the exhuast is quiet.... but if a seller acts irrational then thats a sign of something hidden???

there should be plenty of boats for sale in that price range for you.

It could be the internal flappers in the exhaust tips, i had them in my corsa slant cut tips it sounds like a lot of banging going on but once you put it in silent choice it goes away.

There's alot of good boats out there. If he wants to be a dick find another!

I'm just going to walk away from it. Too many headaches. I appreciate the feedback.
