This trailer originally came with my Sunfish, but I quickly repurposed it to carry Moga on our vacation. It wasn’t ideal, the bunks were 2x4s with some moving blankets screwed down. I used this setup for two years before deciding to make some improvements in 2021. The roller up forward had started crushing the edges of the keel, and the bow stop put black marks on the paint.
I built a platform to support the keel and keep the trailer from scraping the paint off when I launch. I also lowered the side bunks and moved them ahead a bit. After the platform was built, I took the wheels off to repack the bearings and change the dust covers for some Bearing Buddies.
I’m glad I did because I was greeted to a handful of rollers spilling out of the hub when I took the wheel off. This trailer is pretty old and I don’t think the bearings have ever been replaced. Anyway, I bought some new A-4 bearings, packed them, and got the wheels installed again.
Next I stapled some bunk carpet to the new platform with stainless staples. There’s a wooden block that supports the keel’s rocker up forward under the carpet. I added a jack too, so I don’t have to move the trailer with a dolly or the winch handle. The red bow stop is new as well, the previous one was a black rubber roller that left black marks on the bow. Hopefully this one doesn’t make my boat look like I ran over a scuba diver.
Of course the wiring had quit working so I decided to permanently fix it. I bought 25′ of 7 strand 14ga trailer wire so I could run individual ground wires to the lights. I’m not going to use the trailer as a ground again, too much corrosion. The purple wire is the second brown wire to the brake lights, and the blue wire is the second ground. The red wire isn’t needed at all. I wired everything up with solder heat shrink fittings, which seem to work really well. These things have a little blob of low temperature solder in the middle that melts with a heat gun. After testing to make sure it was wired correctly, I wrapped everything in a few layers of electrical tape. Probably not as good as amalgamating tape, but I didn’t have any.
The boat is supported much better and hopefully there’s no way to scrape paint off now. The trailer jack has taken the room for the spare tire, but I plan to make a bracket for that later.
