Alright I have a 1648 with gator glide that shallow water customs built for me with a 36 pro drive stock on it except for the prop and it is a Hopkins. I'm getting speeds average 25 to 26 running between 3900-4100 rpms with me (180lbs) my brother (160lbs) 10gallon gas and a 70 qt cooler full. Is that about right speeds or should it be going a little faster? Reason I'm asking I'm seeing people post that they are running higher 20s with bigger boats than mine. Just curious to hear what others have to say about it.
