I have a 21' Wellcraft with a 1998 Johnson 150 Ocean Runner. Shifting into reverse is smooth. When I continue to accelerate, there is a point when I get a little speed, but it takes a hard shove to get any additional speeed, which casuing me some trouble when backing out of slip in wind and current. When pulling back harder on the handle, you better hang on, because you are now moving way too fast. Any ideas?<br /><br />Thanks,<br /><br />Dave
