I have a 2000 mercruser 3.0L, 181 CID inboard on my pontoon. It seems that if the boat is run at a high PRM 3-4000 and then idled down quickly to shut off, it fails to shut off right away. The engine seems to continue to turn and surge for up to 10-15 seconds and then shuts off. Anyone have any ideas. Thanks in advance.

Re: Engine waits to shut off

Don, your opiniotn on this please.

I have a 2000 3.0L mercusier inboard in a pontoon boat. The boat runs OK for awhile and out of the blue while pulling the kids on a tube in will bog down. I have noticed it happens around the 3000 RPM level, I have to lower the RPM and increase again. I have changed the fuel filter and plugs. Can anyone help a new boater out with some ideas? Thanks.
