My boat's current shift knob is interesting. It is a male threaded knob that is aftermarket. I ordered a plain wood shifter knob with a parts order a summer ago and was immediately confused when I tried to replace the knob.  It dawned on me today that what I am looking at is the aluminum insert of the old shift knob? I have looked thru a bunch of old posts. All the shift knobs I have seen on these controls look like a normal female threaded shifter knob. This would explain why only this remnant part of the lever is corroding in that manner.  Before I tried to file flats on the base, I would appreciate some expert advice. Currently my boat's shift knob threads into these threads.  I now think I can remove the corroded threaded insert and I will have a normal lever with the standard male threads on the end. This piece has acted as a threaded union for who knows how long on this boat.

That's odd. What brand is that throttle mechanism? What model and year is this on? ------------- Previous: 1993 Electric Blue/Charcoal Ski Nautique Current: 2016 Ski Nautique 200 Open Bow |

All I have looked at were Morse Controls but yours does look odd. Is there enough stock to run a Die down and cut new threads? It looks like part of your handle broke off inside your old shift nob? ------------- |

I was able to cut 4.5 turns of threads in. I had to use a file to reduce the diameter of the shaft. I blew up the top threads by not using the file first. This will work for awhile. 1987 sn2001. Should this boat have the mv2 in it?  Sorry for the flip. I tired several time to get it right, left handers...  Thanks for confirming the handle should be chrome. |

We'll just assume that he edited his post and added the year and model after you asked your question Pete

| Mv1 with that housing through 87. They switched housings in 88 but the collar didn’t arrive until 89. Not sure if both are considered the mv2 (the internals are the same either way). |

When I had my 78 Nautique one of my friends would twist on the shift knob while driving. I did not figure it out till he had stripped it. I think it was just a nervous twitch but he certainly stripped my knob. It was summer and I wanted to use the boat. I put that stripped knob back on with JB Weld. It was never loose again over the next 10 years I owned that boat. I forgot about it until you had this issue. Add some JB Weld and forget about it. Merry Christmas. Mark ------------- |
