Low power creeping up?

Check your exhaust elbows. I had it where inside of the tip of the elbows was blocked off enough because of rust that the engine wouldn’t go past 3100 RPMs because at low rpm the engine kind of pulsates back a little bit ingesting a little bit of water that eventually builds the wall inside of the exhaust elbow tip.

That would be sooo cool 😄 thank you for the comment, my friend

Hey my friend, thank you for the comment. I really appreciate it. If a Mercruiser 4.3 engine stalls when RPMs exceed 1200 and the carburetor has been cleaned, there are a few possible causes to consider, including a fuel pump issue or an ignition coil problem. Here's how to test these components to determine which one might be the issue.. Fuel pump test: To test the fuel pump, you'll need to check for fuel pressure. One way to do this is by using a fuel pressure gauge. Connect the gauge to the fuel rail or fuel filter and turn the key to the "on" position without starting the engine. The fuel pressure should read between 3-6 psi at idle and 6-8 psi at full throttle. If the fuel pressure is low, it could indicate a problem with the fuel pump. Another way to test the fuel pump is by listening for the sound of the pump when you turn the key to the "on" position. You should hear a strong, steady humming sound coming from the pump. If the sound is weak or intermittent, it might indicate a problem with the pump. Ignition coil test: To test the ignition coil, you'll need to check for spark at each cylinder. You can use a spark plug tester to do this. Remove the spark plugs, connect the tester to each plug, and crank the engine. The tester should produce a strong, consistent spark at each cylinder. If the spark is weak or intermittent, it might indicate a problem with the ignition coil. Another way to test the ignition coil is by checking for continuity. You can do this by using a multimeter to test the primary and secondary windings of the coil. The primary winding should have a resistance of 1-2 ohms, while the secondary winding should have a resistance of around 10,000 ohms. If the resistance is outside of these ranges, it might indicate a problem with the coil. Let me know what you find out my friend, also a couple other spots that could cause problems. I’ll give you an example no longer ago one of my engines started to lose power gradually to the point where one engine was way stronger than the other, and then all the sudden I started having high RPM issues, after chasing my tail for a very long time turned out that my exhaust elbows was partially clogged up by the very tip, I didn’t really think that it could clog up like that but it does. Also, a little trick that I use chasing down a fuel problems is a little glass filter that you can add before your fuel pump and after to see if you have air leaks anywhere., Remember that before the fuel pump is a vacuum Side of the pump after the pump is the pressure side of the pump so before the fuel pump issues, you will see bubbles in the line and after the fuel pump you would see fuel dripping Also, I know that this goes without saying because it’s usually the first thing that people will tell you to look for, but make sure that the vent for the fuel tank is not clogged up. Also, the fuel pick up tube inside of the tank are notorious to crack or develop small pinhole leaks or that screen on the very tip of it gets clogged up, I hope this helps at all my friend once again thank you for the question

@@Cruisingthesouth thanks for the tips, i will let u know once i found out the problem.

Hey bud, thanks for the comment, well, for as far as I understand it the only difference for the automotive is that the gases are rerouted to a charcoal chamber or filtration system because of emission regulations where the cruisers the gas is just get sucked up by the carburetor and it spit it out on the exhaust, I think the cars are just different because of emissions, but there could be more to it

Silent pain of boaters 😄

What’s up bud!?

You cant surf in front of wake. Thats not how wake works. LMAO
