Jetboat owners:

We can repair your marine tube-and-bundle shell style heat exchanger.  Or, if the unit is not repairable, we can supply economically priced brand new coolers.  Please just send us a few pics with application info and some of the basic measurements (such as shell overall length, shell diameter, resevoir length, and mabe some center-to-center measurements of the various inlets/outlets/connections).  We may be able to just use the number stamped to your cooler as well.
