Name your Palette: Description: http://manitoupontoonboats.com/blog/getting-your-pontoon-ready-for-spring/ | As soon as the cold weather starts to lift and the snow begins to melt, it is the perfect time to take your pontoon back out on the water where it is meant to be. However, it is important to first make sure that you have done everything you need to de-winterize your pontoon in order to ensure that it is in prime shape once spring rolls around. When preparing your pontoon to get back into the water after winter, be sure to give it a thorough inspection.
