you're in luck that it is a FI/PCM engine, as it can be scanned for specific faults. I'm willing to bet one of your fuel delivery sensors is outbound.. take your pick: throttle position sensor (TPS), or manifold absolute pressure (MAP) sensor. it could also be a vacuum leak, evidenced more by the fact it does it on your outbound leg. an intake manifold leak, where it marries the heads and block, can leak a bit, and then seal itself when the engine warms.. they are hard to find. more

I'll tell you something else, too- that I would likely do just because: distributor cap. I've seen them be cracked and have water infiltrate, and cause all kinds of issues from misfires to limiting ability to achieve RPM, just to dry themselves out under the heat of running, and work fine. and it's a devil to diagnose because usually by the time a mechanic gets it, it's already dried. the only real indication for that is difficulty starting it up. are you having that issue at all?

*** I've not experienced it, ever, but it stands to reason that a pending code, while it is happening and before the ECM/PCM corrects itself, may in fact beep.

Search the archives in the box at the top of the page for a few key words like rpm or whatever. Sure seems like we've seen a few of these threads that have "limited RPM". I haven't experienced it but have read through the posts and it seems to be a variety of things from fuel filters to protection faults that limit engine damage from overheat scenarios. Drew has quite a few ideas to check too. [links]

was it replaced with a duplicate engine?

Under heavy acceleration, the engine bogged down and stumbled. Unless I let off the throttle, the engine would die. However, if I accelerated slowly, I could reach full RPM and maintain WOT indefinitely. more

Where should I start my troubleshooting this weekend? Spark plugs and plug wires are fairly new. I installed a new cap and rotor in 2013, and have used it limited hours since. Cap and rotor inspection will be my first task Saturday.

The Mercruiser 5.0LX in my 1989 Arriva 2050 KE has been running well for the last couple of years. I rebuilt the 4-bbl Quadrajet in 2013 and haven't had any issues since. That is, until my last outing

I checked the accelerator pump, and it's squirting lots of fuel into both sides of the primaries and appears normal. Choke appears to be operating normally. [links]

When the engine misfires, you may have trouble getting your boat up to speed. Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on the accelerator. [links]

Armed with this information, your mechanic will have your boat engine hitting on all cylinders and running smooth in no time. here

A misfire usually starts out as being merely a nuisance but if the causes aren’t identified and corrected, it may result in your engine not starting or stopping altogether when you least expect it. more

If you’re experiencing a misfiring engine, you’re likely going to need to enlist the services of your mechanic. Before you take your boat or engine to the shop, gather as much information as possible to assist your mechanic in diagnosing the problem.
