Delay and bang when outdrive goes into gear

[dennison17]

I have a 2004 Cobalt 240. Big block Volvo with same outdrive system.

I just had it into the Cobalt dealer for a full tune, oil change, outdrive service... the whole 9 yards. After a short run, I notice that periodically when I pull up on the tab under the throttle cable to put it in gear... and push the throttle forward (expecting it to immediately engage), it delays engagement...and the motor rev's for a couple seconds, and then it bangs into forward. Before the service was done, once you pulled up on the tab under the throttle and pushed forward, it immediately engaged. No engine rev, no bang. Hmmmm.... This doesn't appear to happen with reverse (but I haven't exhaustively tested this in reverse.) Is this just an adjustment? Any advice? I really do not want to take this back to the dealer prematurely and have the boat sit for the next four weeks in their backlog.

Sounds like the drive cable is out of adjustment. I am assuming they took the drive off. Very easy to check yourself at the back of the stern drive.

Thanks for the feed back. We checked the adjustments and ran them all one way and then back again in the other direction and it did not seem to help. I DID verify that reverse works fine, the problem is just when its going into forward. I have it at the dealer for a quick look

I'm having the same issue and from research and checking it sounds like the clutch isn't engaging fully or slipping.

Soooo the issue is resolved. The cone clutch had to be replaced (because I'm told that there was water in the unit from a broke seal. They also had to replace a couple bearings I the upper pat of the unit. Hmmmm....
