    Seadoo Sportster 155hp 4-tec loss of power when turning left

    I have a 2005 Seadoo Sportster 155hp 4-Tec that I have on for two years with no problems. The boat is all stock with no modifications except for a stainless Solas concord impeller, which was installed on the boat when I received it. My boat usually runs around 7000 RPMs at full throttle. Today when I took the boat out I noticed that every time I turn the steering wheel even slightly to the left the boat acted as if I was at half throttle. As soon as I turn the steering wheel to the right the RPMs jump right back up. The impeller looks good and the wear ring looks good. I don't know where to start with diagnosing this problem. Any help would be greatly appreciated!

    Check your pump first and the steering nozzle. Make sure there is no obstructions and it's mounted correctly.

    Make sure that your reverse gate is locking in forward.Seen this happen a few times usually that is the cause.

    This is partially normal. You can expect this to happen to some degree, but probably not as much as you describe. Is your engine low on compression?

    Would a broken motor mount do this?
