I don’t know enough about both of these boats to make a recommendation, but to be worried about the low hours on the motor as new as an 2018 would not bother me a bit. Definitely the lower hours gives the motor an advantage. It’s not like the boats been sitting for 5 or 10 years, those low hours would be very attractive to me, but I don’t know anything about the boats which would be a heavy consideration. The hours on both are low. Good Luck!
