New "Gatling Gun" High Volume MercTrans Oil Cooler

In a cooperative effort with San Juan Engineering, a newly designed high capacity Merctrans transmission cooler is now available. The original oem cooler does not hold enough volume or surface area to allow for proper cooling of the two quart (synthetic type F) oil accomodation of the case. Test trials showed an average of a thirty degree drop in oil temperature due to increased surface area and the internal water volume of the " Gatling Gun". Every cooler comes complete with a winterization kit and installation instructions. Pricing is $279.95 with free UPS ground shipment within the contiguous U.S.

    Please note that the cooler outlet "must" be rerouted "thru-hull' above the waterline in order to obtain maximum flow with resultant optimum cooling. A 3/8" Moeller bulkhead fitting is recommended (Part# 33210-10). Temperature monitoring is also wise, as overload and overprop can allow for consistent temperature climb when cruising long nautical distances. Autometer produces a high quality electric gauge with proper degree scale for the Mertrans (Part# 7357). The Merctrans should, at optimum, remain at 175 degrees or below, with 195 degrees being the maximum operable temperature.

***WINTERIZATION INSTRUCTIONS***

The MercTrans Gatling Gun cooler must be blown out with compressed air for proper draining. The cooler is a "two pass" system, and will retain raw water if not winterized properly.
