See why we called it the "Max System"?

To keep Simrek's Multiport Driveshowers out in front of all our competitors, especially those that have simply copied our designs with a couple of added gimmicks and colors, this latest design of pick-up ports and mounting bracket system is now Protected by US Patent #7,666,042 B2, Issue Date Feb. 23, 2010.

If you've been reluctant to install a drive shower because you didn't want to drill holes in your drive, we have the answer. Our latest innovation; brackets that mount the shower using the lift ram assembly. Not only will this new mounting system NOT void your MerCruiser Corrosion Warranty, but it makes installation a snap. Simply swap out one bolt at the top of the drive and two nuts (or clips) on the lift rams.

Anyone that has used a garden hose knows that if you remove all the sharp bends from the hose, you will increase the flow of the water. Our new pick-up port system does just that. Gentle bends through out the entire system not only reduces drag, but it drastically increases the flow and volume of water to the top portion of the cooling system.

It is common for many new boats to come equipped with drive showers that are mounted by drilling hole in the anti-cavitation plate. MerCruiser is now saying that doing so will void your corrosion warranty. When asked about drilling holes in the drive to mount a shower, Rick Lang at Mercury Marine replied, "If an aftermarket component causes a failure, or in this case leads to corrosion damage... our warranty will not cover the damage/failure". Also, for SeaCore product "under no circumstances should the surface of the finish be damaged or it will corrode and there will be no warranty". These new showers still use a pin located near the inlet which acts as a debris filter. By dividing the tube in half, anything small enough to get past the pin will also be small enough to get out the dump ports. We have the only system that guards against the shower plugging up with debris, which without warning; will cause them to failing at cooling your drive. We remain the industry leader because we offer only cutting edge designs, not gimmicks! We are often copied, but as always, the copiers will always be lagging behind the innovators.

Do any of these conditions detract from your boating fun?

A Multiport Driveshower could be the solution.

  • By removing 55 to 65 degrees off your drive oil operating temperature.
  • They include Pick-up Ports that supply water at any trim angle.
  • Won’t plug up with debris because of its water filtration system.
  • Locating the pick-up ports outboard of the anticavitation plate and ahead of the prop eliminates the potential for causing prop cavitation.
  • They install in 10 minutes or less with no drilling.
  • Formula Boats uses them as standard equipment on many of their boats. Why didn’t your boat come with one?

We are now the most copied drive shower on the market.
