My son and I have been restoring an 24 foot '82 GW Weekender with a GM 305 V8 and stern drive. We are about a week or so away from completion of our project. Does anyone have any idea what I could expect on top speed and fuel milage? Our boat does'nt have trim tabs yet and it's my underatanding a lot of fuel could be saved by adding them. What cha think?
