"Sound-Selection" Air Activated 4" Exhaust Diverter System - "Captain's Call" Replacement
Single Engine Standard Exit System For Small & Big Block Chevy

At last you can have the very best of both worlds. You can go from marina quiet thru-prop exhaust to the open water roar of thru-transom exhaust. With no cutting or modifications, these highly polished stainless steel exhaust diverters install simply to both stock and aftermarket exhaust systems. But that's only the half of it. What makes the Hardin Marine Sound-Select Diverter America's No.1 choice is it is air activated - yes air activated - the same way the factory original guy's do it. You ask why air? Reliability and safety. Reliability because we DO NOT retro-fit electrical solenoids as marine exhaust components. Electric solenoids produce a continuous draw of electricity while generating possible sparks and heat in an enclosed engine compartment. An air operated system is driven by a remote mount panel providing none of the side effects electrically operated systems have. So if only the best will do for your boat do it the way the factory intended to do it - Choose the Hardin Marine Sound-Select Exhaust Diverter!

Each Sound-Select Diverter system is constructed of aerospace stainless components. The systems are sold complete with 2 diverters, and 1 remote operation panel. Exhaust tips sold separately.

These kits are designed to be fitted in stock bravo exhaust locations. See this measurement sheet for more info. If you must place tips in a different location more hose and angle bends may be required. Call us if you need any assistance. Note: This is for Mercruiser Bravo Applications Only! Will not fit Volvo/OMC applications.

These diverters will fit Bravo and Alpha applications 1987 and up they will not fit the 8.1 engines, OMC or Volvos.

The Mercury 350 dry joint exhaust will not work with the Hardin diverter.
Corsa has a set part number 270-61000 for standard non riser spacers. If there is space, we need to know if it is 3" or 6" and Corsa can build a custom set.

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
