    Is My Impeller Bad? Mercruiser 228

    It's in the title and my bio sorry haha. Bits and pieces. My brain scatters. Mercruiser 228 is a 1979 system that was originally a carbed 305. Now it is a 350 with throttle-body injection, but still the MC-1 outdrive. Fresh-water cooled.

    Is My Impeller Bad? Mercruiser 228

    Update: I just put 3 quarts of antifreeze in the system. Now it is running back at 170 F (digital gauge) at 1500 RPMs on the hose. And my IR temp gun at the thermostat housing says 170 F on my gauge is actually 155 F. That is the outside of the thermostat housing and manifold of course, but that...

    Is My Impeller Bad? Mercruiser 228

    Okay long story. It is still running hot. The overheating was not because of the impeller, although it was good to replace it thanks all. The engine threw the belt that runs the water pump and the alternator. That is why it overheated. I did replace the impeller and housing though...

    Is My Impeller Bad? Mercruiser 228

    Good to know. I have run it on the hose at high RPMs many times over its life. Will not do that any more I guess haha. Just ordered an entire new pump kit. Thanks!

    Is My Impeller Bad? Mercruiser 228

    My engine is overheating and I am trying to track down why. Below are the pictures of my impeller. The video is of the outdrive hooked up to a hose running at idle and WOT. What do you guys think, is that how much water it should be pumping or should it be more? The outdrive is an old MC-1...

    How Much Voltage Drop Is Too Much?

    Thanks for the replies y'all. Almost all my wiring and gauges are the original from 1979 so you confirmed my suspicions. I also left the key on and drained my cranking battery twice. I did not realize it was weak since it charged right back up and kept 12.45 volts. Rewiring my boat it is, along...

    USB charger

    I put a double one of those in my boat about 5 years ago. Still charges without a hitch. If I remember right, it was like $6. I put mine inside the cuddy though so it is very protected from the elements.

    How Much Voltage Drop Is Too Much?

    Howdy all! I am trying to determine whether my wiring harness and instrument cluster has too much resistance and draw and needs updating. With my 3-wire ignition switch in the off position, the hot wire reads 12.45 volts, which is what the battery reads. With the switch in the run position...

    Tachometer Bouncing Causing Engine Surging

    I mentioned I tried that in my long-winded post, but good suggestions. I found the problem though! The positive side of the coil was only getting around 9.5 volts! The Pertronix wants 12 volts. The positive side of the coil is where the Pertronix gets its power from. I do not think there is a...

    Tachometer Bouncing Causing Engine Surging

    It says it is self-tuning so we will see if I get the darned thing running properly. I can manually change the AFR per the RPMs too. It has Coast Guard compliance so I'm hoping it works. When the tach isn't on drugs it sound great on the hose.

    Tachometer Bouncing Causing Engine Surging

    I see the confusion I created. When the carb was on it, the tachometer would bounce around but the actual engine RPMs did not change. The tach would just momentarily read wrong. With the sniper on it, the tach will bounce and the Sniper will inject fuel thinking it needs to for the increased...

    Tachometer Bouncing Causing Engine Surging

    Hello all. I need some schooling on how the RPM signal is generated. I just replaced the carburetor with a Holley Sniper EFI system on my Mercruiser 260 setup (old carbed-style GM 350). My tachometer and the Holley Sniper unit will jump up and down in RPMs when that is not what the engine is...

    2012 F20 Starts, But Putters Out Quickly

    Took the boat duck hunting yesterday in as rough of seas as a 14' with a 20 horse can take. Nice cold Washington saltwater spray in the face at every wind wave. Engine performed flawless for the 5 miles out, and 5 miles back. Didn't die once and have dinner to show for it!

    2012 F20 Starts, But Putters Out Quickly

    Well I took the carb apart a second time and shot compressed air through all of the jet and followed it with carb cleaner. I found that two jets might have had a tiny bit of what appeared to be gasket glue or something in them. Anyway, I cleaned it all up, put it back together and back in the...

    2012 F20 Starts, But Putters Out Quickly

    Yes I have. The primer ball has hard to pump, and I'd like to think it ran a little better, but I'm not sure that it did... I did check the carb gaskets and they appeared fine, but a rebuild kit never hurts. Just strapped on cash right now. I didn't try a different fuel line because I do not...

    2012 F20 Starts, But Putters Out Quickly

    Hello all! I have a 2012 Yamaha F20 remote start that started running funny. When I start it up it runs fine for 20 seconds or so, and then it sputters out and dies as if it runs out of gas. The gas is fresh, non-ethanol gas and the fuel filter is clean. It seems to run fine when I rev it, but...

    2003 Suzuki DF140 Nothing Out of Telltale.

    So there was a little bit of confusion about what got blown out. I asked them to blow out all the ports leading to the block again so they did that and found a lot of junk in the port connected to hose 9. They also took the cover off the crankcase and found a lot of junk in there. It's peeing...

    2003 Suzuki DF140 Nothing Out of Telltale.

    Hose 18 goes to the telltale. The engine had 4 anodes, all were crumbled to pieces. They have all been replaced now, but there are definitely pieces that could be dispersed throughout the system. We have flushed it out as best as we can, but we're just unsure of how the water flows through the...

    2003 Suzuki DF140 Nothing Out of Telltale.

    Salt. Heavy corrosion. Always flushed but still suffered major corrosion. We are wondering which way the water is supposed to flow throughout the block since we are not getting water to the oil and fuel coolers.
