    I finally found the alarm.... all wires look like they are intact except for this one red wire that i have pictured ....i tightened up the mount where the lanyard attaches and now it will kill the motor when you remove it but still no alarm......does this red wire that anyone can tell need to have 12V going to it..... and on a NOTE the red wire is coming out of the larger connection down stream of the lanyard mount...... the buzzer has a pink wire running to it if that helps

          Did you ever change the impeller before?

              Wonder where all the fins ended up? Probably a few in various nooks and crannies of the motor.

                Wow, how many hours you got on that motor?
                I got 2006 with 1650 hours and did the impeller once just preventive maintenance about 4 years ago, looked like new.
                actually kept all the replaced old parts as backup

                    You really need to look for / remove the missing vanes.

                    Their in the engine somewhere..

                      i have 260 hours on the boat.....i was really shocked that the impeller was completely destroyed except for the center...... i have found probably 95% of all the vanes....just pieces all over the place..... i cleaned out the lines and pretty much everywhere i thought pieces could go ...... i did notice the key way slot was smooth inside so i am thinking the keyway slot stripped and let the impeller slip.......

                        Keen to see pictures.
                        Would think unlikely for impeller to slip. Is the key missing?

                          That's weird!
                          Perhaps someone started the outboard dry?

                            It's not unusual for the smaller engines to loose the vanes. Read about MANY of them on this forum.

                            It's good you found most of the vanes and should be ok. Never read of the key way splitting(as it's designed to), the rubber / vanes go away, melt (no cooling water, etc)..

                            The larger engines, the vanes just take a set. Pretty rare for the vanes to break away.

                            If there's ANY discoloration / distortion to the SS cup, replace it and all the O-rings. Just a little distortion WILL cause issues..

                              this is off topic but like to ask you favour, could you please check on your f60 if you have any play on your prop up down left right?
                              It would feel like slight click click moving it.
                              Thanks
