Hey Guys hope you can help. I have a 1994 Four Winns 190 Horizon with a 5.0 OMC with EFI. It starts and runs and idles great. My problem is this. When running around 40mph plus...I hit the trim button to bring up the lower unit to gain a bit more speed. Every time I hit the trim button...it seems the engine stutters or cuts. When I release the trim...it runs fine. I'm hitting the trim button for about 2 seconds at a time.<br />I took it in to the marine...and on land...he couldn't duplicate the issue. Almost seems like some kind of "short" somewhere. <br />Issue number 2: when running wide open...at top end...the engine appears to "miss" every once in a while and you feel a slight slow down in speed. <br />I had the tech guy pull the plugs....(which haven't been changed in 4 years) and he said they look brand new. Engine has about 260 hours on it.<br />I'd appreciate any insight into this. Thanks so much.
