Starting monday and working through today on my free time I made/installed New Qtr. doors with vents to help keep the bilge dry and happy while its stored in between fishing trips.Then I had a custom Stainless radar mount welded for my Raymarine Raydome (installed a new interconnect wire to it also) and drilled,wired and mounted it all on my stainless t-top(which I had custom made a few months back).Then I performed a pre-season High performance tune up with BRF9HIX Irridium plugs and new Magnecore wires.I also installed a SST 13 7/8" x 17 pitch prop with a new SE Sport 300 hydrofoil and changed the lower unit fluid from 90w to 50 sae V twin oil to lighten the drag..Cant wait to run it and see how the Tune-up and newly installed SL72plus Pathfinder Radar works on the open sea! I got a bunch of pics as I did it all.Take a look!

Hey CSC,
Welcome to CSC,
Are you running a JohnnyRude? They require supression plugs or you risk blowing expensive electronics. My 150 calls for Champion ql78yc supression and nothing else. It didn`t idle great and I called Monty Racing as they make serious power with Rudes. They recommended ql77jc4 plugs and they are much smoother. I would not run those plugs. The heat ranges vary greatly among different brands and you could risk preignition/detonation and blow the pig. I am not fond of Champions, but you gotta run em.

Cheers,
GFS

i hate to agree but champions are the only plugs recomended in omc out boards i replaced with new ngk and the old champs worked better and new ones were better everything else gets ngk
good luck

Thanks for the sparkplug info.I have a set of cooler 10hix which are hard to get....Maybe I try them first or is there a reason Irridiums should not be used period??
My outboard engine guy also was the one that recommended them.? I was running ql77jc4 before and it lugged at idle...but as for the HIX plugs I am leery now since I dont want to hurt the motor at all.I appreciate the input.

Are they supression plugs? If not your power pack may not like the decision.

Ok...Just got off the phone with NGK support.Feel free to contact them with any spark plug questions.

The product support represenetive says that the 86' V4 90hp Johnson can run the BR9HIX plugs and even said his book specifies a BR7HIX or BR8HIX specificly for this engine.Upon cross referencing the heat range,He also stated these are in the same heat range as the QL77JC4.
