Slight Bog on take off

[wutagoalie]

Hello all, I have a Alpha one 3.0 Merc on a 2002 boat (not sure what Gen, but Manual #26). I have had a slight bog for years now and cannot figure it out. If I ease into the throttle slowly, I have no Bog. If I hammer the throttle as if I were pulling a water skier, I have no Bog. If I throttle down at a normal take off pace the engine bogs down to almost a stall, I then have to pull back on the throttle and prevent the Bog, then it will allow me to take off again without an issue.
Any Idea's?

Is this a carbed boat? Sounds like the accelerator pump.

That is what I was thinking.

Yes, it is a carbed boat, with 2 throats. Where is the pump located, does it need to be swapped out or simply adjusted?

It is part of the carb internals, gets refreshed and adjusted as part of a rebuild.

Rebuild kits are cheap and include the parts you need to fix a bad accelerator pump.

It's June. At least try shooting some carb cleaner in there while it's running at high idle. Might be able to put it usable for the short term.

Had a similar problem on my 83 3.0, found I was over propped and also did a carb rebuild and now it is fine. I can get a slight bog if I have idled for a long time but after a good run it goes away. I have a long canal to get to the lake from my favorite launch and I can get a bog after that long ride at slow idle.
