Hello! I am new to being a boat owner as i picked up a 12 foot 1977 valco aluminum boat a few weeks ago. I finally got some time to take it out on the water this week and I have some questions. I have 1977 johnson 15 hp engine on it and 30 lb thrust trolling motor with battery and 6 gallon gas tank all in the back with me. When it would get out of a plane the bow would come down enough to where i could see over but then it would start hopping and had to slow down. I looked it up and saw a picture that maybe could explain why but im not sure. i didnt have my motor down as far as it would go it was maybe mid way up. Just thought there was too much weight in the back. im not very big im about 160 pounds and had my ice chest in the middle of the boat. So im wondering if there is too much weight in the back or if i need to try to put my motor down more and see if that will help. New to all this so any advice is very helpful! Thank you.
