when I try to get it up on plane it sometimes bogs down slightly for a few seconds before it gets up and going.
No surge. Actually I have to let off the throttle, back down to idle, do it again, then all is normal.
Last time we had this type if problem was probably 10 years ago, it was the piece the throttle cable attached to cracked off. JB weld held up for the last 10+ years. Didn't seem to be messed up this time. This has only happened the last 2 times I took it out.
