Took the boat out a couple weeks ago, ran great for a while - not a problem whatsoever for ~45 minutes. All of a sudden the thing started choking, and eventually stalling. Fired it back up, and would inconsistently surge and stall. Every once in a while when starting back up, it would seem like it was running fine then start to have probs again when trying to get on plane. Sounded like a fuel pump issue to me, I'm running an unknown brand mech. fuel pump that a rebuild kit doesn't exist for. (This thing has been leaking before) So I bought a new pump - is there anything else that may be the cause of this? Fuel filter is clean, tanks dont seem to have any debris.

I'm assuming that you already made sure you don't have water in the fuel as well. Did you check for water in the seperator? Did you check for a loose connection ground/hot to your ignition? Doesn't really sound like a fuel pump problem to me, but I could be wrong. I suppose a bad mech fuel pump could cause what you are experiencing, I've just never dealt with what you are describing with a bad fuel pump.
