It seems I can make the easiest of jobs oh so difficult.

She was running great all summer but then for some reason, she started bogging at mid throttle. Runs great at WOT but when I cut her back to cruise around 3000 rpms, starts to bog like it was starving for fuel. If I immediately hammered down, right back up to WOT like nothing.
So I've had boat 3 summers and winterized properly and treated her well with good oil and good fuel. First thing I tried(because it was easy and cheap) was new fuel filters. No help at all. Runs like a champ wide open but bogs at mid throttle.
So the next thing I try (suggested here, and cheap) was to rebuild fuel pump and accelerator pump. Seemed pretty straight forward. Problem is, after fuel and accelerator pump rebuild, it's worse. Now it will idle and run slow all day. When I put the hammer down, she takes off and dies about 15 secs later. So here's my questions.
1. What would cause the OB to run fine at WOT but not at mid throttle?
2. What do you think I screwed up when rebuilding pumps? Bad fuel line connection? Bad reassembly?
One thing I did notice is that the accelerator pump has two mounting slots. I should have paid more attention when I took it apart but there is some allowance for where it can be mounted.
3. Where should the button on accelerator pump be when in neutral. Right against the (name?). Slightly below? I have the shop manual but it only describes its function but no details about testing or installation.
So that's it thanks for looking. I'll spend about 1-2 more days trying to figure this out myself or with the help of anyone here. Otherwise, off to the pros.
