With approx. 120 hours and a boatload of idle time on my G2, it seems like it might now be idling a bit rougher than when new. I’m thinking about installing new plugs, but I’m stumped about the port side lower plug, which is partially blocked by the cover shroud. I’ve seen the techs installing new plugs on a G2, and they disassemble a whole bunch of stuff to get to that plug. Is there an easier way? For one thing, I don’t have a tool to insert in the hex-shaped plug at the back of the engine, so I’d either need to buy one or fabricate one if I want to start taking all that stuff off at home. I don’t mind paying the dealer to do necessary jobs, but it would take me weeks to get into the shop at this point in the season, so I’m looking at alternatives, if there are any. Thanks in advance for any insight you can provide. 2018 G2 225 H.O.
