Spark Plug Question

[Jolicious]

2 Parts:

1.  I do a lot of fishing in "No Wake" lakes.  Should I change my plugs regularly?  I am guessing that since I do a lot ot idling around that my plugs need shcning due to build up?

2.  If I do need to change plugs, is there any certain brand that you guys reccomend for a Johnson 200 Venom?

Thanks guys!

I always keep a spare set of indexed plugs in the boat and change plugs when one starts skipping or every couple of years if I think about it.   It's recommend you you replace them every time you decarb the motor, but I use an old set to decarb and after making one WOT run at the lake, I take the old set out and put my good plugs back in.  If not then, it's recommend you replace them each spring at the start of the season.  I'm too cheap for that and may run a set two or three years.  

A couple of miles of WOT running will usually burn off any idle build up.   Running long and hard at WOT I would run Champion QL77's.   If a lot of no wake and little WOT, I would run Champion QL78's.  

I also always buy several extra's, index my plugs and once I get a set indexed, I use my engraver an etch that cylinder number on the plugs metal body so I always know which hole it goes in.  It's very unlikely you will get six plugs to index properly is the reason I usually buy two sets at the time.  Don't matter the motor, all motors run better and make better power if the plugs are properly indexed.  I do my vehicles, even do my lawn mower, weed eater, chain saw's etc. like I said, I index everything
