Re: Attention Joe Reeves
M.A.<br /><br />Plese do not duplicate threads. It get's confusing. Your previous thread has been transferred here and the other thread has been deleted.<br /><br />From previous.<br /><br />I went to replace the plugs on my "86" Johnson 150, I wasn't sure which one to get because I had left the one I pulled at the house so I decided to use thier manuel and look up the year and model. From what I thought I remembered the plug was a QL77JC4/L77JC4 about $2.49 ea. but the catalog showed a plug (forgot the # ) $8.49 ea. so I asked one of the guys there and he said go with what the catalog said. I then saw a Clymer's manuel and looked in it and it showed me a totally different plug all together a UL77V $4.79 ea. Thanks for the assist! <br />--------------------------------------------------------------------------------<br />Posts: 9 | From: Dade City Fl. | Registered: Jan 2005 | IP: Logged | <br /> <br />marinegrh <br />Petty Officer 2nd Class <br />Member # 32191 <br /><br /> posted January 26, 2005 08:58 PM <br />--------------------------------------------------------------------------------<br />those plugs are all used on that engine i believe, they have different heat ranges but omc loved to use the heck out of those ql77jc4's...however i am looking at a cross reference and a 86 150 should take a ql16v price is going to be what the dealer wants, id try napa first though they are pretty cheap <br />--------------------------------------------------------------------------------<br />Posts: 140 | From: jacksonville florida | Registered: Sep 2003 | IP: Logged | <br /> <br />walleyehed <br /><br />Commander <br />Member # 26896 <br /><br /> posted January 26, 2005 10:42 PM <br />--------------------------------------------------------------------------------<br />My book shows UL77V as the prefered plug with an alternative of QL16V.<br /><br />--------------------<br />Kenny<br /><br />--------------------------------------------------------------------------------<br />Posts: 2166 | From: Texas, Kansas and somewhere in between | Registered: Jun 2003 | IP: Logged | <br /> <br />M.

I just couldn't figure out why the QL16V was 2 times as much as the UL77V.Oh well thanks again! <br />--------------------------------------------------------------------------------<br />Posts: 9 | From: Dade City Fl. | Registered: Jan 2005 | IP: Logged | <br /> <br />DJ <br />Fleet Admiral <br />Member # 5471 <br /><br /> posted January 26, 2005 11:45 PM <br />--------------------------------------------------------------------------------<br />IMHO, a bad choice.<br /><br />Read my resonse on this thread.<br /><br />

What this means to you is greatly reduced radio interference on your cell phone, vhf, radio, that sort of thing. On later engines they have to run it because the interference screws up the VRO warning system. You've got a choice.<br /><br />FYI, the V indicates it's a surface gap plug, and the L indicates the length of the threaded part. The numbers are the 'Heat Range' and it's super-important that that is right. Champion decided to change all it's numbers so 77 is pretty much the same thing as 16, which confuses things a lot. <br /><br />The QL77JC4 is the 'regular' plug version of the UL77V with a proper ground electode. Again, this is a suppressor plug since it's got a Q in it. There is also a L77JC4 out there. Many people here have found that these plugs work pretty good too - especially at low speed. Now I'm just repeating what I read here, so listen to those with experience with it!<br /><br />I suspect your really expensive plug was a Champion 5828, an outragously pricey 'Marine' version of the QL77JC4. It features a stainless steel shell. Frankly, since you end up throwing them out ever couple years, I don't see the point.<br /><br />Hope this helps! <br />--------------------------------------------------------------------------------<br />Posts: 2626 | From: Nova Scotia | Registered: Nov 2002 | IP: Logged |
