hey guys need some input,im looking at a tr 175 2002, with a 90 hp mercury on it boat is in great shape runs good, the guys was asking 5,000.00 and i got him down to 4500.00 is this a good price and is the 90 a decent motor,and how fast should it run he told me around 45 - 48 does this sound right because i wont get a chance to test ride the boat,he is an older guy and selling because g5 grand kids and all want to fish, what do you think pull the trigger or not?
