questions about my evinrude intruder 175hp

Hopefully Ferm or Spare will jump in here, but all opinions are welcome.

So my neighbor (retired mechanic) was looking at my engine with me and became concerned that the hoses are not routed correctly. Some pics are attached. He used some terms that I can't remember, but he really isn't familiar with this engine type at all... though it looked over-engineered.

His concern was the routing of the hoses on top of these pics... looks kinda like a bypass. Looking up the parts breakdown, he could not find a tee in the hoses and thought mine looked weird. I thought it's possible that I improperly rerouted them with the engine disassembled.

Also, the hoses coming off the carbs is different in each side. Anyone familiar with how these hoses should be properly routed? The engine runs great, but is hard to cold start, and the plugs foul up rather quickly.

Thanks
