Hi Joe!! I also (currently) have a 2002 PT175 w/75.. It's been a really good boat and does a nice job... But I'm soon going to go to glass -- it's a long story....
Welcome Joe - GREAT boat! So what's the top end you've had her up to. I've loved my 40 on my 175 but when I load it up with kids, wife and gear i'd LOVE the extra 35 horses!!!
