I have a 1997 Sea Ray 3.0lx that runs great except it has a couple of minor issues. I hope someone can give me advice on working out these issues.
1st issue
If I throttle up slowly, when I get to about 1500 rpms (my tach is probably not correct but it's a point of reference) the engine starts to "bog". It feels like it's getting too much gas. If I accelerate past 1600 it smooths out and runs flawless. If I accelerate quickly (like pulling a wake board) it doesn't miss a beat and I never feel the "bog" at all. I will describe what I've done below....
2nd issue (maybe related to 1st issue)
It runs a little rough at idle after the boat is warmed up. I have to give it a little gas after it starts up and pump the accelerator a few times to hold idle without conking out.
New plugs (gap to specs), wires, distributor cap, rotor
Timed in "base timing mode" to 1% Top dead center (to specs)
- Base timing seemed to do exactly what the manual said it would do
- Timing verified at reputable boat repair shop
Removed all gas and ran about four tanks of fresh gas (fishing and playing)
Tried all three positions on the carb accelerator pump
Had carb rebuilt at a very reputable boat repair shop (new pump, needle, etc..)
