Question about saltwater fishing boats

[Questor]

Mr. Dahlberg:

Can you explain why 2 or 3 big outboards are preferred on many saltwater fishing boats instead of inboard engines? It just seems like the inboards would be better suited to fishing than a boat with a transom full of outboards.

Thanks.

hp to weight ratio, cost compared to diesel, and in some cases the safety of an xtra engine.
