The Winterizer

The solution for easy winterizing your powerboat

• the FAST & EASY way to WINTERIZE or FLUSH a marine engine

• installs salt neutralizers or antifreeze
• removes seawater, antifreeze, sand and rust particles
• unbelievably fast - flush two V8's in less than 10 minutes
• no more crawling around the engine room

After years of winterizing marine engines for winter storage, we have developed an innovative way that will revolutionize the winterizing of an inboard marine engine. The WINTERIZER System  makes this process faster and lot easier.

The purpose of winterizing a marine engine is to protect the engine block, exhaust manifolds and coolers from splitting or cracking from trapped water in the cooling system that will expand when temperatures drop below the freezing point.

When utilizing The WINTERIZER System to remove this water from both sides of the engine block, both exhaust manifolds and oil cooler on a typical V8 engine, this process will take the user LESS THAN FIVE MINUTES, removing trapped water very quickly and efficiently.  As well, some boat owners also install antifreeze when winterizing to reduce internal rust and corrosion that can happen over the winter and by using the The WINTERIZER System, boat owners can install antifreeze just as quickly as it removes the water.


Due to the designs of boats and where they put the engine drains, this task of removing antifreeze is not easy – until now.

The WINTERIZER System will easily remove the antifreeze and in a way that you can easily store it to be used again year after year. This will help our marine environment. Remember that all marine life is very sensitive to all types of antifreeze. The WINTERIZER System will also keep your engine block and manifolds free of sand and debris when used on a regular basis. The WINTERIZER System can also be used to remove the bilge water that the bilge pump cannot remove, this means a dryer bilge that doesn't smell.

Lastly, The WINTERIZER System will make your boat maintenance faster and easy. Made with only the highest quality of materials to meet the high quality that marine equipment demands. The newest and strongest plastics that will not scratch, fittings that will last a lifetime, and hoses that meet marine quality.

Please Note
The WINTERIZER is the same system as the Sea-Flush, a system for boat owners that want to flush sea water from their marine engine. Please visit
