Will QL77JC4 champions work in 1985 90hp evenrude? .030 or .040?

Re: right plugs

yes, gap .030 if you do a lot of idling or trolling go to .035.

Re: right plugs

99% chance you need to clean and rebuild carbs, have you done a compression and spark check?

Re: right plugs

Before adjusting the cables you need to test it in the water under load.It will act totally different than in the driveway on the muffs..
Here is the spark plug chart,

Absolutely. Different ball game when in the water.

Re: right plugs

Thanks for the help,I have actualy put it in the water 2 times,first time it shifted fine then I changed the lube in the foot west back to the lake and every time I shifted into reverse it jumped in and out,maybe it dont like new lube?

Re: right plugs

Changing lower unit lube won't do that, although I have little knowledge of the bigger hp motors. I see you adjusted your shifter cables. Hopefully, that's the problem. How does it run in forward? Does it slip in and out then?? You sure don't want to keep letting it do that, as it will ruin your clutch and rev. gear.
