If the float drags on the inside of the fuel bowl, it could easily cause flooding when the needle valve doesn’t close against the seat. Overflowing the bowl past the designed fuel level is likely the cause of the dripping fuel you see at idle in the Venturi area. At idle you should never see...
I also suspect a battery issue causing the alternator to go into full output mode. I suggest that you pull the battery/ batteries and have them load tested at a trusted shop. When removing the battery clean the connections on the battery terminals and the cable ends.
So after hearing from a few folks I could do this. Have the “Test Fuel Pump” ready to install. It would consist of 3/8 fuel hose, an in-line filter and of course the pump, along with the correct fittings on each end. If the issue repeats itself, I can by-pass the current filter and Mercruiser...
1993 Chaparral, 2050 Cuddy. 4.3 LX . Engine Serial OD 843641. So I replaced the Fuel Pump 2 seasons ago. Mercruiser $400 part. Original one failed. I just experienced a fuel issue and needed an emergency fuel delivery. $$. Seems okay now with only a short run back to our home dock. Either the...
When you removed the old oil filter did the gasket seal stay on the engine block? If so, there will be two stacked gaskets on the new filter once installed. This will quickly lead to a catastrophic oil loss.
To be clear about the relief spring in the alldodge pic of an oil filter mounting base - which shows the oil filter BY PASS VALVE. It’s job is to allow for oil circulation around a totally plugged up oil filter. Better to get dirty oil delivered to the engine than to have no oil at all. The OIL...
Perhaps begin with a battery voltage test. This is battery voltage even before you turn the key and crank the engine. Typically 12 to 13 volts. Now leave the voltmeter hooked up to the battery and crank the engine over. Watch the voltage go down. Typically 11 to 10 volts remains at the battery...
If you are changing spark plugs you will always need to check and correct the gap on the new plugs. Otherwise you should not be attempting this service on your engine. I would compare this to filling the tires on your car without checking the tire pressure when you’re done.
So it looks like your ignition system uses breaker points. Old school but dependable if you maintain it. With the key on and engine off, Coil positive voltage check should be 5 1/2 to 7 1/2 volts with the points closed. Coil negative voltage should be less than .2 volts with the points closed...
You did fine. Ignore the dipstick reading until you start up and run the engine. Check for oil leak at the filter. Rev it up to 2000 rpm. Observe oil pressure on the helm gauge. Shut her down and clean up your mess while the oil drains back to the oil pan. After 15 minutes or so you can check...
The power valve circuit only opens up a by pass passage around the main metering jets. When the power piston senses engine load it moves downward to open up the power valve at the bottom of the fuel bowl. This is where extra fuel will supplement the main metering circuit provided by the two...
Look closely at the seat of the spark plug. The one with red paint is called a tapered seat. The cylinder head is specially machined to match up with this style spark plug. The other spark plug uses a flat gasket to seal against the cylinder head. Again the cylinder head on some engines is...
Just to chime in a bit here. Please do all the maintenance items during the off season. That way you won’t be breaking down during the boating season. Nobody likes an interruption when traveling on their boat.
Or try this. If it’s possible to get into the water safety, engine off, disconnect both of the trim ram cylinders from the rear of the out drive. Pretty straightforward. Now you can use a ratchet strap to hoist the drive up to trailer position. No loss of hydraulic trim fluid.
