You don't really need it. Its handy enough, but for small motors you can just pull it up when you beach it. The trim is nice when you are going fast and want to plane it out. That varies with the weather/ waves. You can do that manually with a bit it experimentation. If you look at the "clamp" part that hands on the transom, there are a variety of holes back there with a pin that cam move vrom one to another. That is what that pin is for. People had boats long before power trim and tilt.... Its about what YOU want.
