    Sport Tech Outdrive Cooling Shower

    130-10 + Option(s)

    Stainless Steel "Sport Tech" Outdrive Cooling Shower

    The advent of sleek modern boat styling has brought the need for a smooth,fitted,exotic styled drive shower. Something that blended seamlessly with today's modern boat styling. But looks were only half of the battle performance is the real reason you purchase a drive shower and through extensive testing we have developed the finest drive shower produced today. First our engineers computer modeled the exact dimensions and size of the bravo out drive. Next we spent hundreds of hours studying the water flow characteristics as they entered the drive shower cap to develop a series of water diverters and dams to allow equal water distribution to virtually flood the top of the bravo outdrives factory bearing cap. By retaining the proper tolerance between the shower and the outdrive cap we are able to literally wash the heat away from the out drive providing maximum heat reduction. This unit is coupled with our exclusive 80 degree high volume pick up and -10 stainless steel braided hose and best of all it's virtually a stunning part in the end. So if you are looking for a shower that’s actually truly engineered to perform there’s only one the Sport Tech shower.

    NOTE: For Integrated Transom Assembly (ITS) applications, please call us to get the correct hose assembly. Also note, when installing on ANY Integrated Transom Assembly (ITS) Caution must be used to make sure the trim limit switches are adjusted to the point to eliminate any potential interference between the drive shower cap and the ITS cover
