A couple days ago the quickstart feature stopped working. On a cold start it idles 300-500. After it warms idles to specs. on a warm start it does the same 300-500 thing again. Instead of revving high for a few seconds like it's supposed to. Now the big problem. Returning to the dock yesterday, running 3/4 throttle, then slowed for another boat. put the trottle down to wide open. Rmp's only went up to 3000. Felt like I lost half an engine! Slowed, tried again same thing. Also noticed a vibration. Checked all the plug wires. Checked the plugs when I did the 10 hour service and they all looked good. 2002 90 Johnson with 35 hours. Any Ideas? Thanks, Stretch
