I'm not a gasser, but I understand the problem... is there any way you can increase the volume of air moved by the existing blowers (install bigger fans, from bigger boats with bigger engine rooms, maybe?) and, perhaps, also find a way to increase the ability for more make up/replacement/cooler fresh air to enter the engine room through bigger/additional air intakes?... I'm no expert, but, pure physics, it seems like a possible approach?
Redesigning the airflow won't really fix the problem and may potentially create other problems.
Vapor lock (if that's what caused the problem) is fuel boiling in the fuel lines. Relocating a fuel line or even wrapping a fuel line in (an approved) type insulation should alleviate the problem.
Another problem is the fuel mixture. Was this old fuel that's been in the boat for a long time? Or is this "winter blend" fuel that was left over?
