The aluminum fish boat is an extremely practical and functional boat which has probably
out-sold almost any other type of boat. They are durable, inexpensive, light weight, and
come in almost any size.
There's not a lot you can do to the average fish boat to make it run better, but I have
run into a few cases where the handling characteristics needed to be modified to serve the
purposes of the owner. Light loads and single person operation, sometimes causes leaning
and/or porposing. Balancing the load and changing trim angle of the engine just didn't
solve the problem. In those cases, installing a slight trim wedge over the rivets on one
or both sides, at the transom, would permanently correct these unwanted
Wedges are installed as far out, from center, as possible. .
isn't any set dimension for these wedges, as it really depends on the weight and
speed of the boat and the amount of correction needed. The length of the wedges
typically were between 3" to 6" and the height never any higher than
3/8". They can be installed temporarily with stainless screws for testing and then
converted to rivets and sealer, when your sure you have the desired correction. You'll be
surprised how little it takes to make a big improvement in performance, so don't get too
carried away by just putting the largest one on you can.
