NEWKAWIDUDE

So I purchased the 2001 STX 1100 DI it has less than 50 hours on it and is clean to the point I cant find any scratches on the hull or rub marks. It had a new Stator isntalled last year and i have all Maint records for the past 4 years. IS there anything that definitely happens around 50 hours that most owners have experienced or is it a solid machine with routine maint will run without problem .... Now mind you I also own an Express Cruiser boat so Im used to the typical issues that come with boating ..im just trying to keep from being suprised about something. Any and all input welcomed
