as for the front wheel drive on the launches----no problem
i had a 17'skeeter bass boat with a 150 on it and i have a 25'chriscraft deep V hull with a 15o on it and i never have a problem with my mini van-fwd only.
as for the boat my choice would be an 18' V hull bow rider.
theres more room for the family with the open bow.
full windshield with a camper top on it so you can get up and walk around.
as for the motor there both good motors, just make sure you dont under power it.
if its rated for 140 dont go below 115.
a lot of dealers will advertise a boat thats rated for a 140 but put a 50 or 75 on it to keep the price low to attract
the buyers.
