My buddy just got a new boat last year, it has a LSA for an engine, the issue is, he is getting about 8-10 hrs of run time per fuel pump. Does anyone have any ideas on what the issue may be or what fuel pump to use? I havent put any amp meter on the pump power leads but i'm leaning towards to much amperage...thanks in advance.

As in wire too small causing hi amp draw?
pardon my old age /ignorance, WTF is an LSA ???
 
You will probably not get any information from the C Dory group, unless they are recycled performance car buffs. The only reason I know anything about the LSA (and other LS series), is that my close friend was Kent Enderle, of Enderle fuel injection/ performance parts. Sorry I just don't see a 6.2L V8 General Motors supercharged engine, at 600 to 700 HP in a C Dory! :P

You need a more powerful pump (and all of the associated wiring) as the HP is increased on these engines. He should be able to get specific pump numbers from his custom parts supplier.

The LS series is awesome. I wish I had one in something! My experience with electric fuel pumps that die way too often is they are not staying cool enough. You didn't mention where this pump is. In-tank pumps stay cool because of the liquid in the tank. These generally live a very long life if the person keeps a decent amount of fuel in the tank. In line pumps need ventilation and need to be away from heat sources. They also make a surprising amount of heat all by themselves, so hiding them away out of sight with limited airflow is not the greatest idea. Of course....adequate wiring is critical too. Lots of variables.....but they hate heat.
