Low budget OMC twin project

**sWaltsu** · 02-01-2013

problem is way to get gear shifting rod.

Long shaft model. the way is like pipe. Old, short shaft was only a bolt.
it is very hard to drill hole in the middle on the bolt.

What hes trying to say is the vertical steering tube is solid on the electric shift and the mechanical shift is hollow because the shift rod goes through it, just take the pivot shaft of the short shaft and drill it, or take the pivot shaft out of the long shaft shorten it and install it in the shorty.

Could someone explain to me how that OMC electric shift worked? I've eyeballed diagrams of it but don't see what's going on.

Thanks,

Merc man Jeff

I believe the porting is the same for the 50hp and 60hp blocks for 81 through say 85, this is essentially the same porting as the sst45.

sst45 guys turn over 7k, you might want to put fresh bearings in while you have it apart.

correct, thanks bill...i don't think I have any apart or I would post pics. To me its easier to do that than find or pay what people want for a short Stinger mid.

The short mid for the two banger is not the same as the short stinger mid, they are usually easier to find and cheaper.
