Patrick,
I am in process of attempting this. I have purchased the Lewar new level, as noted in this group discussion. It is availalbe at Defender "Lewmar Complete Shift Control Mechanism - 89400108" The handle attachment is a bit different than existing, but I think it will work, if I can get the old one out. Everything is rusted and frozen on the pedestal cap and old handle.
I also ordered cables, also from Defender. They come in 1 ft increments. When I looked at mine and measured, I noted that one was longer than the other. Didn't seem to be an issue as it just give more lenght to make the arc/radius to exit under base of pedistal and curve back into engine compartment. I am not sure if the longer one is a good or bad thing, but making gentle curves are i think important. The longer cable was 15 foot. I think I could have gotten away with something shorter, but ordered two at 15 foot. I think these are the correct style, Defender has two brands. I ordered the Uflex MACHZero Universal 33 Series Style Engine Control Cable brand Item: #2185667 | Part Number: MACHZEROX15. I am going up to boat tomorrow and will be there all week. I hope to just look at what I have and lay them out and see if they would work, correct ends etc. Not sure if I will have time to install this trip.
Hope this helps. Happy to get feedback from anyone else who has done this.
