I have a 1998 150 johnson fast strike ficht. the plugs that came out of it were xc12pepb. my question is can i replace them with ql78yc? any help would be app. thnx, lance. i dont know what johnson specifies and dont wanna blow tha motor!

that first plug doesnt sound like the one thats recomended my 97 200 uses the champion plug you have listed but mines a 200, but id bet it takes the same plug but ask someone else to confirm it

ql78yc is what I found it calls for same plug I run in my 96 200 Evinrude

i bought the ql78yc and cant get a socket on it once its hand tight. like there is no room for a socket. any suggestions? the ones i took out (xc12pepb) were smaller and i could get a socket on them

I dont know on that Lancer that is just what plug chart says it takes my 200 is not inset I can actually put a boxed end wrench on my plugs without a problem maybe one of the experts can step in and help with this one.

well i sure thank you for your input . i did go out and look on the motor by the serial number and boat info. and it says to use the xc12pepb, so guess i will go withwhat they say! got tha lower unit lube changed so i got one thing accomplished yay hahahah!

I had the same problem. Couldn't get a socket on the plug. My dad had an old wrench that fit the plug. This is why he is a genius at times. He shaved the outside of the butt end of the wrench(circular end) down with a grinder to where it fit snug down on the plug and the outside didn't touch the hole. And BAM! Now i have the perfect plug wrench for whenever i need it.

Looks like your trailer tires are too big for the fenderwell. Have you up sized the tires and does the tire contact the fender well on bumps/potholes?

?????????????

Just noticed that the tire appears to have no room to move inside the fender when hitting bumps.

cant you use a open end or boxed end wrench

my dad has the same motor in a 175. only use that same plug. dont try anything else in there! xc12pepb. they're expensive but alot cheaper than a blown motor! also make sure they are lined up with mark on all of them when you tighten them down!!

I dont pretend to know anything about that engine....but I've had to buy a cheap plug wrench and take a grinder to the outside of it, in order to make it fit into something I was working on before.

hey big mike how do i line up the marks or mark them? i heard something about this but not sure what to do?

the tires on here are fine. It's a brand new trailer and came from the factory with these tires and rims! rides smooth too!
