Hey 1515 finned water jacket fits leopard 4074

Just sitting with both motors and a cooling can, noticed the motors looked about the same size minus the fins on the castle.
Tested it on the leopard with a syringe full of water, holds more pressure than the cooling system can supply, when the blocked line blew off the cooler the water shot about 5 feet across the kitchen!

The Neu15 jackets from Steven do as well. Im running two of those in my cat and they are great!

I replaced the brass water inlet/outlet with bigger hole, that did lowered their resistance.
