I just bought a new boat ( 1st ever ) . It is a 1448 MV alumacraft. I have a 25 merc jet for power. I have taken just about everyones word to help in this process and so far feel like I am doing well. Until I got to the trailer. I went with a cheap new one. I am not sure the exact size, but pretty sure it is close to the smallest you could get for my boat. On suggestion I bought some trailer guides. Instead of the long 2x4 type I got the roller guides ( great deal and I like the idea and the look better.) Now my buddys telling me they suck. Can someone shed some light cuz I reviewed these, and guy love them. Plus my buddy is one of those guys, if he doesn't have it, he doesn't like it. With my little aluminum riveted 14' I can't see adjusting the boat to be that tough and I am hoping the guides I got will get me in and out of the water great . I can adjust before I strap down.
