Anyone help with info on 19ft Scarab jet?
 

I just bought a 1997 19 Scarab jet. It has a 4.3 Merc 6 cylinder and a volvo jet drive, 177 total hours. It should be reliable. I know nothing about jet drives. Just looking for some guidance and what to look for. Were there many of these sold? Are there many around? Going to be a nice lake boat. Any info on thier history would be a great help. Thanks Joe
