yeap about 15 to 20 hours, I have had good luck na 650hp since 2000. going to check cam wear this winter maybe change springs ran it for 7 yrs before doing the bottom over 2000. don't care for merc stuff over priced you can get a jc perforamce 800 or 850 598 that will out last a merc I bet or dee tyler crocket on his efi motors. artie if in mass theres coughlin motors in norwood or jim reid in whitman mass .
