I have a Comp 90. I just bough it this summer. After 16 hours of working the transmission overheat and stuck this is more than 1500$ damage, as I look closer my PCM engine I notice corrosion underneath 13 years old is an old boat you definitely need to replace a lot of stuff such ass electric cables, switches woods under carpet, steering maybe.......................... Of course everything is depending upon GOOD MAINTAIN of previous owner! Get all service records of the boat you decide to buy avoid boats used in salt water and of course before you buy try!
GOOD LUCK (I wasn't)
