Hey everyone, gotta question for you all.

Yesterday, took boat loads of kids tubing as part of a church youth activity. I noticed some very strange and definitely physical throbbing in the throttle on the SB motor. Noticed it most when coming off speed and near the idle throttle position with rhe bucket fully open.

It doesn't feel fuel or motor related.

Wondering if this is from the rudder? I'm in my first few weeks of ownership with a ruddered 240.

Any other suggestions?

Have you confirmed the bucket is fully open at that throttle detent ? maybe it's not adjusted properly ?

I get that all the time coming off the throttle especially tubing/surfing its like the buckets are half way. I bring back both throttles/shifters to neutral and go forward all gone. Almost like you have to reset the buckets. Do you have any finns installed?

No fins, I find the rudder does a nice job steering. Had fins on my old 2005.

I will look at the buckets and make sure they are aligned properly.

That's kinda good, cause I thought it might be my fins.
