    spark plug question

    It is in fact a Vortec engine and it's in a 21' Blue Water CC that I regularly run to Catalina Island so I can't really rule out the overworked idea but at least now with the new plugs in I'm not afraid to try to start it. Thank you people.

    spark plug question

    1996 mercruiser 4.3lx 6cyl 4bbl Was told running a different spark plug (not as hot) may help with a deisleing problem I am having The manual calls for a AC-45MRT plug. The replacements have a longer shaft and I'm concerned about them making contact with the piston. Is that possible?

    Can't slide the remote into forward gear.

    1996 Sterndrive 4.3lx 6cyl. 4 barrel carb with Thunderbolt ignition. Alpha one Gen two. Had this out a few weeks ago and it shifted and ran fine but was dieseling when I shut it off. I set the timing, idle and changed plugs. Next I was told to change the impeller. I had the two bolts above the...

    Engine dieseling

    I think there's between 50 and 55 hours on the plugs. They appear to be burnt right under the letters ACDelco. Also I was told these plugs are not the right ones for vortec heads which I have.

    Engine dieseling

    Following the list of suggestions for getting rid of the engine dieseling problem I've had. First thing I checked was the timing and it was advanced. I have clear hoses going to and leaving my thermostat. I shut down before fixing the timing because there was no water showing in the hoses. I'm...

    Engine dieseling

    My thanks to all of you, I now have a direction. Gas lines, plugs, timing, better fuel.... I can handle that. hot spots in the cylinders, not sure what to do about that. make it last on the list and hope it's fixed before I get that far.

    Engine dieseling

    1996 Sterndrive 4.3lx 6cyl. 4 barrel carb with Thunderbolt ignition. At idle, wot and everywhere in between it runs fine. The problem I am having with it only occurs when I turn it off. With the key in the off position, it keeps trying to run. Not in a smooth way, the engine kind of coughs...

    Stuck again

    I got the tools from different merchants for around $10 ea. They were all from Amazon so unlikely genuine Merc. The last thing I tried was a 6 point torque. Very little meat left to grip inside the pin but I will try again with the opposite side of a new tool with chemicals and applied heat...

    Stuck again

    96 Mercruiser 4.3LX 6cyl 262cid 4bbl alpha one gen two A week ago I came on asking for help removing a stuck outdrive. You all got me through that but it came out with the gimbal bearing seized to the drive shaft so bad a hammer didn't budge it. A couple days of cutting, grinding, heating...

    outdrive stuck

    Round two with the 2x4 it was down for the count. Did someone say rusty u joints and a gimbal bearing seized to the shaft?The way it was running on the water I expected to find a bunch of broken pieces when I opened it up but did not. The main bellow had no water or gear oil and only some minor...

    outdrive stuck

    Looks like another busy morning with the wood. To a beginner like myself, these forums are an absolute life saver. I can't thank you people enough for all your input. My first thoughts went towards crow bar, wedges and Grub's hammer. So glad I refrained.

    outdrive stuck

    I tried the 2x4 and ended up with 1/16" gap. It's very loose. I can shake it up and down as well as sideways. But it will not slide off and I've been trying all morning. I attached a pic and avi file if you wouldn't mind looking at it and see if I'm doing it reight

    outdrive stuck

    I don't understand. what is a shift dog? is it where the cable from the front connects to the back? the remote is still in forward position. the shift shaft is still facing forward and can only turn the prop clockwise from behind.

    How do you pin point the source of a loud vibration

    I filled the lower end with the pump from the bottom hole until it was running out the vent and plugged both holes. Then I filled the resivoir in the engine compartment. Shouldn't more than a half quart have drained out originally?

    How do you pin point the source of a loud vibration

    96 Mercruiser 4.3lx 6cyl vortec with alpha one gen two outdrive. I took the outdrive off and installed a new water pump kit. Who ever did it last broke two of the four housing bolts off and left it like that. I drilled them out and mounted the new housing with 4 new bolts. Didn't see any other...
