Need some input. Just bought a new Montauk. While waiting for some new canvas the boat was put in the water by the dealer so I could use until ready. When I picked up to take home the bottom was covered with algae and the waterline on the sides of the boat was permanently discolored. I had asked the dealer to powerwash the boat before I picked up so it would look nice for the ride home. The dealer said this is typical with the rivers around Wisconsin (one which emptys off Lake Michigan). He then proceeded to say that I should have bottom paint put on which would reduce any staining from water, but this wouldn't fully do the job. I was not happy about this. If I had known this would happen, I would have had the bottom painted before delivery. Anyway, I got the boat home, got under with a soft brush and hand rubbed some of the algae away. Their is however, a permanent stain on both sides of the hull where the water touched. Would certainly appreciate hearing any feedback on what I should do. The Dealer told this would happen no matter whre I put the boat in and would paint the bottom when I put it up this winter.

MaryKate On/Off. It is an acid that will eat the algae and restore the hull to its former glory. Orange bottle about $8-10 at any marine store. Possibly K-Fart, etc.

You can also use Starbite's Instant Hull cleaner. In all of these, the active ingredient is oxalic acid. It gets rid of the yellow water stain in about 60 seconds.
Pour it into a spray bottle, spray a little on a rag, and wipe. Have a hose available to quickly rinse it off, especially from a galvanized trailer. I have used this stuff for years to keep my Whaler hulls looking like new. It is important to use this chemical immediately after coming out of the water. If you let it sit for a week, it will me much harder to remove, and you will have to buy the oxalic in powder form, such as Bar Keepers Friend or Sudbury's HD Fiberglass Cleaner.

If you're keeping the boat on a trailer, don't bottom paint it. It's a profit center for the dealer and cost to you. It's constant maintenance and will hurt it's value around the Great Lakes. Most trailer boaters hate it. However, if the boat is going to be moored for the season, you must have it unless you're going to haul it every 2 weeks or so and clean it.

I agree with Bigshot. There's little need for bottom paint in our freshwater. Granted, you may have to spritz the hull now and then for "river goop", but that paint is not only expensive, but (in my opinion) ugly.
If you want, you can have the bottom paint I'm removing from my 15, although it's stuck to peel-away backing...
