I have a 2003 FX Cruiser with 175 hrs. I do not believe the plugs have ever been removed. I would like to change them. The ski is giving me no problems, running great, but I think that is to long of time for the plugs not to be removed. I have not tried removing them yet, not even trying to remove the plug boot. Since the plus are recessed and there have been incidents of plugs breaking, I would like any pointers before I try this simple process. I do not want to break a boot or a plug. Any tips? What are the chances the plugs are going to be frozen to the head and not want to break loose? Just want as much info as I can get before I attempt this. Thanks.
sounds like you're very stressed out over something very simplistic...if you're really that worried, spray some pb blast around the spark plugs and let penetrate for a while.....grab the boots by the whole, not the wire, and pull off. take a correct socket and gently turn counterclockwise.
Yes I know it is simple, but the plugs I think have been in there for 14 years. The boots have been on the plugs for 14 years. I just wanted to see if anyone thought that might be a problem and know if there was any process to get them out when they haven't been touched for that long. I just didn't want to break anything. Thanks for the reply.
Max is right. Just spray some down in there, and twist and pull the boot off. Apply some antiseize to the new plugs, and dielectric grease to the boot (I just make a ring of grease around the plug hole).
Not yet. Just bought the new plugs and it as been raining for the last 3 days. Did take off 1 of the boots though to see if they would come off. Will try as soon as the rain stops.
OK, no worries. Plugs came out fine. Hardest part was getting the boots off. Have no idea how long the plugs were in there, but they came out easily. They also look good. A nice brownish grey. One other thing though. I am running this ski without the element filter. I really see no purpose of it in a water element, except water protection if it flips. Filter seems to be fairly clean, but it slows the ski down several mph when used. Any thoughts about running a 4 stroke without the filter? Lake use only.
I read somewhere not to use antiseize on NGK plus as they come with something on them already. I did not notice anything on them, but read that if added you could easily overtighten the plugs. I did not add anything. Remove and add?
Always use antiseize on plugs especially in an aluminum head. As for over tightening they only need turned in finger tight and just snug them a bit. No need to make them farmer tight.
Probably a little late on this but I agree with everyone. The only think I would add is to invest in a decent torque socket wrench and actual spark plug socket. I broke the ceramic neck on my volvo boat engine once cause I was lazy. A spark plug socket has a rubber insert inside that protects the spark plug. Also, torque spec for your plugs should be around 20ft lbs but check your manual to make sure. I don't use antseize but that's probably good advise from Dave in DE that I'll start doing.
