i ran the boat tosay and got a top speek of about 36 knots according to my gps in a light chop with no trim the accelaration is still a little slow but the top end is very good i need to look in to the prop and i am going to have a new water pump in as well. i might have tham look at the out srive ratio like macjoe menitioned but for now i am happy but its that darn ethanol fuel that is causing all this i hate it
