DONT take the boat out without first purchasing either Boat US or Sea tow towing insurance. that is NUMBER 1 on the boat owners list.
Is your merc an optimax ???? if it is while expensive, use Optimax oil.
only use stabil if your going to let the boat sit for a long time.
only time I ever use it is during winter storage.
buy the biggest screen GPS you can fit on your boat, as you will find it much easier to find the areas that will hold those little blackfish you like to fish with shrimp for
best of luck with it !!!!!!!!!!!!!
