My Yamaha 115hp outboard is giving me fits at low rpm, mostly idle speed. It starts fine and runs like a top when above idle, which as about 800 rpms. But when idleing it sounds like it's missing a beat (new plugs only 5 run hours ago). I had brought it to a mechanic a month ago who said he could find nothing wrong, it was running great. But if it does stall, it then becomes very hard to restart. Once started, when I give it throttle, it may start fine and I can run at 30 mph at about 5500 rpms with no problems. Or it may bog down as if it has no power and stall again. It's very frustrating. My neighbor gave me some gas treatment (1oz per 6 gallons) which he says will help clean the engine a bit which may help.
Any suggestions? Thanks in advance for any help.
