Welcome aboard,there are some members with that engine,that don't have any problems,the early one's did but if this one is still around it should be fine,the 225 is more boat but your tahoe would pull it just fine,i used to tow mine with a 98 f150 with no problems,when it comes to boats it's very common to say if my boat was only two feet longer,can't tell you how many times i wished i would have bought a 245,so if you find a nice 225 i say go for it,and like Pete said a hard top won't make a difference towing
