I have a 99 2000 Intimidator with a 200 optimax turning a 26 tempesst plus prop when I get to about 5500 RPMs the rear of the boat feels like is takes a slide to the left. Im not sure what is happening when this happens, so I just back out of it. I Dont want to blow out if that is what it is trying to do. its usually around the 73-74 mph range. I have tried trimming down a bump or two but it still does it. I also noticed it is worse on slick water. Has anyone experienced this before?
