New to the forum. I logged on last night and have learned more about outboard motors in the last 12 hours that any manual can teach me. <br /><br />My question is: what is the gap setting for the spark plugs for a 1990 Yammy 150 Pro V. I am having trouble with it. It fires right up, idles, and will go about 5-10 mph, but boggs down when I try to advance the throttle. Spark plugs looked a bit fouled, I have cleaned them and want to check the gaps before I put them back in. Any other ideas? I just purchased the boat and don't know much, so any info would help and be much appreciated. Thanks
