BOOM, Ive got it lol, I could drill a small hole in the engine hatch, make a bracket like you said on the bell housing, but have the bracket and the bottom of the pole be threaded, just screw that bitch in ! 
There you go partner, perfect idea, you can use a rigid coupling on the bottom bracket, and use a 3/4" rigid conduit for the pole or if you wanted to use something lighter, you could always thread it, I'm a sparky so that's why I am thinking electrical parts to use haha, good luck man and hope it works out, update with pics when you do it man, would like to see how it comes out 👊🏻👍🏻
