    Mercruiser 4.5l low vacuum, WOT 4350 and higher fuel consumption

    Why do you think it's struggling to breathe? If the throttle isn't opening all the way And the timing is retarded, that seems like something the PCM is doing on purpose. I'd like to see a graph of demand vs throttle opening at WOT throughout the rpm range. I didn't see any knock sensor data on...

    Mercruiser 4.5l low vacuum, WOT 4350 and higher fuel consumption

    Oh, gotcha. Looks like everybody was thinking that was relative/gauge value. Not sure what "arbitrated" TPS means? Is it drive by wire system? Also, looks like these values are at steady state conditions rather than WOT (otherwise demand should be 100% the whole time)? In other words, if you...

    Vacuum should decrease with throttle. At WOT it should approach zero.

    Mercruiser 4.5l low vacuum, WOT 4350 and higher fuel consumption

    Your manifold pressure is going the wrong way. At idle was the vacuum steady? You said you replaced TMAP, is that the MAP sensor? That would be my initial thought, or intake restriction somewhere. Is your throttle opening all the way? Fuel trim is good, which means that whatever air it thinks...

    So, another one. This is more than mildly concerning I think. https://www.cnn.com/2026/07/30/tech/anthropic-ai-models-break-out-hack

    1997 5.7L thunderbolt ignition. Slow crank

    Much easier when hanging, but possible without. Raising/lowering the front with a hoist is much quicker than turning the adjusters individually a turn at a time.

    [SPLASHED] I/O (Sterndrive) Conversion to Outboards

    Where did the mercruiser #'s come from? scott's link looks like the VPs are closer to your current setup than the stock OB setup. Anybody have the skill to overlay all 4 graphs? Ted, do you have a GPH graph of your new setup yet? Also interesting on the VP test that there isn't too big of a MPG...

    [SPLASHED] I/O (Sterndrive) Conversion to Outboards

    1. Do you have that graph from your old setup? 2. I'd like to see an MPH x Time graph...wonder if they'd still overlap EDIT: Oooh... Space the dots out every x seconds, and keep the rpm v. mph on the axes.

    Only thing I don't like about removing the lags is messing around with a penetration into wood. Mine are gooped in there pretty good with 4200 now.

    Engine misfires after rain storm

    Yup, I also assumed carb initially and rebuilt it yet again. If you don't have one for your 'rude (and if it's a CDI type system), definitely get a DVA. Nearly impossible to troubleshoot properly without one. The merc also has a spark at the plug, but very weak. About to (hopefully) fix it with...

    Engine misfires after rain storm

    Yeah, ha ha actually going through that right now with my Merc. Has spark with the light but weak on a gap tester. Still a good first test I think, and if it's missing you know it. Also guessing that a weak but not absent spark is more common with a stator driven ignition, multiple places to...

    I mounted my pump to a piece of metal, which lays flat at the bottom of the bilge. It's stable enough that I never fastened it to anything. Easy enough to remove and replace
