    Replacing Spark Plugs Mercruiser 4.3L - Coolant Hoses In The way! Help!

    Coolant now topped up with fresh coolant, ran to 80 degrees celcius and kept cap open to burp out the air. Spark plugs finally changed now! To answer an earlier question, it might be with the right tool actually you might be able to get to those plugs after all without removing the closed...

    Replacing Spark Plugs Mercruiser 4.3L - Coolant Hoses In The way! Help!

    Thanks! I think I'll go for 0.045 for these as makomark suggests given that 1. The plugs currently in there looked like they hadn't even been gapped and they were at 0.03" and the engine started up OK, and ran (probably could have been more fine tuned but no major issues) 2. bumping up to...

    Replacing Spark Plugs Mercruiser 4.3L - Coolant Hoses In The way! Help!

    Haha yes I second this proposal! Never thought life would be so hard changing a spark plug! It might be possible the way you say, the problem is to get into my engine bay I have to hang pretty much upside down in there to even get close to the plugs, and the fat closed heating system is right...

    Thanks I was considering this and since it ran ok in my uneducated opinion at 0.03" i might be better off not pushing these plugs past what they're intended for. Why 0.045 out of interest?

    A few people here saying 41-932 was replaced with the 41-993 I'm thinking they would be a suitable replacement which are pre gapped at 0.06". I might pick up a set for another year or so when I next change them.

    Oh sorry these are AC 41-993 not AC 41-933. But still I am assuming the AC 41-933 ones pre gapped at 0.06"

    Oh I see so looking at https://www.ebay.com/itm/226116133646 I see these are already pre-gapped to 0.06

    OK thanks, but how would you ever gap them then if you got AC 41-933 ones? My understanding is they wont come gapped to 0.06"? So how do people normally do that?

    Replacing Spark Plugs Mercruiser 4.3L - Coolant Hoses In The way! Help!

    Thanks I bought the same same plugs as the last mechanic fitted (maybe was a bad idea given he gapped them incorrectly) which were NGK BPR6EFS. According to my friend chat GPT they are a suitable replacement but they are standard nickel electrode not long-life (platinum/iridium) so given they...

    Replacing Spark Plugs Mercruiser 4.3L - Coolant Hoses In The way! Help!

    Super helpful guys! Thank you! AllDodge, so would one way around this to basically be when I pull off the (rather thick) hose, to plug the hose itself AND the "male" part that goes into said hose. Surely plugging them both would stop the leak entirel? My 3D printed part at 26mm width fit...

    Thanks again. Im not sure I am following this part "By plugging the hose it will lower the amount coming out but note the hose on top of the exhaust manifold will drain back into from that hose and out." I think you're saying by plugging the hose immediately after taking it off it'll end up...

    Thanks, I was actually wondering about straining it. I managed to hoover up all 6 litres of it from the bottom of the engine bay and collect it, but the bottom of the bay was very dirty. I asked chat GPT on its take and it was very adamant that I should not re-use it due to contaminants...
