That gets me thinking about getting Gamma done. Gamma is also ready for final paint and re-assembly, But, I am thinking now it should have a 10hp diesel engine in the escape pod. I can mount the engine on a track so it simply slides out of the pod and into the hull if I need to escape with the pod. I would use the engine as a generator to power the thrusters and maybe add a couple of thrusters for more speed since the power is only limited by fuel supply. A shaft or magnetic coupler through the hull would be more efficient but then it is more complicated to remove the engine in an emergency also the pod is not buoyant enough for the extra weight of a prop assembly. </div><div id="yui_3_16_0_1_1457694219242_6138">Things to sort out, </div><div id="yui_3_16_0_1_1457694219242_6138">Cooling the engine- it could be keel cooled or a heat exchanger so it can have proper temperature control and anti freeze.</div><div id="yui_3_16_0_1_1457694219242_6138">Exhaust- I have to think about that one-I would need a valve that can handle the heat or water cool the exhaust. If the exhaust is water cooled then I would need an extra pump and in that case I could use a heat exchanger for cooling. I would like to avoid a raw water pump.</div><div id="yui_3_16_0_1_1457694219242_6138">Fuel- I imagine an external fuel tank is best with a bladder so the tank does not need to be a pressure vessel. </div><div id="yui_3_16_0_1_1457694219242_6138">Much to consider.</div><div id="yui_3_16_0_1_1457694219242_6138">Hank</div></div></body></html>
