I bought my 1989 Scarab new in 1990 I remember the option was about 3000.These boats are pretty strong and heavy, I would think it would be for weight manley for the Kev.I owned my Scarab for 12 years and sold it to a friend that had it for 3.There was a few stress crack in the bottom toward the fron strakes, I really didnt jump wakes so I would think these prob were nornal.I have the original prices sheet s and opt sheet Ill take a look.
I sold my for 27500.3 years ago but it had some stuff on it

I would figure they would be in the low 20's
I would think if they paid for the kevlar hull it would have the 365 mag in it
