So my boat spends most of it's life on the trailer. Very rarely will i leave it in overnight. The harbors around here don't have the prettiest water. Brackish dirty in most spots. I've always used on off hull cleaner to get the yellow stains off which often will appear after a day of boating not even leaving it in. I have tried waxing it etc etc and it still will yellow. I will never bottom paint so it's not an option I just didn't know if anyone knows of anything to put on the bottom to prevent this. Thanks in advance.

KM,

You probably have the original gel coat on the bottom which tends to be porous and thus the staining. I had the bottom of my boat painted white, the same as they would do on the deck. That was the end of my problems.

Good idea thanks. I had thought of clear coating it

Look no further. Stuff is like magic. Wipe on with a cloth, spray off with hose. No rubbing or scrubbing, instant white. AWESOME stuff.

Clean it with something like the above or the works toilet bowl cleaner. Then put some good wax on it .

Star Brite hull cleaner works pretty good too. Spray on , let it sit for a couple , hose off. Wal mart usually has it , a little cheaper than purchasing it at a west marine or similar place.

I have tried some different products that promise to prevent growth and filth on the bottom of the boat without painting. Unfortunately nothing works very well. I keep my boat in a slip for the season but refuse to bottom paint so I pull it every few weeks and clean it with On/Off. I have a ramp right in my marina so I pull it and drive over to the hose station in the parking lot. Then just dump it back in. No biggie really.

After 30 years of good success with labeled bottom cleaners I turned to much cheaper muriatic acid that you can get from Home Depot or local hardware store for mega cheap. I use a cheap garden sprayer to apply too.

Like other bottom cleaners be careful breathing it in. it hurts. Spray away from breeze. Again, cheap garden sprayer makes this better and easier.

This stuff is miraculous, almost magic to watch it work.
