just purchased 1987 18' lowe pontoon with 48 Johnson spl. runs good just wondering about which hole to have trim in. it is all the way down and has 5 holes with a rod through the bottom one. seems like when my wife and son ride with me under top toward rear it doesn't plane out right, can move person to front and put some weight there and it picks up more speed. should I raise motor up a hole or 2 for this or just distribute the weight. don't want front of pontoon to torpedo. new to pontoon boating but really like it so far. thanks in advance for info.
