Trojan mechanical Chain steering

[rossjo]

IMO Hyd steering is a downgrade, but to each his own opinion.

Not me. Lose fluid once offshore and you won't be an advocate. I have 5 boats - none with hydraulic steering. But manual does needs some PM.

Chains come in standard sized and as this boat was made in USA using I assume US parts back then, which should be a standard size, you should be able to match your chaing at a good bearing/bushing supply house as it is usually availabel in bulk.

Good point Larry - not sure what size it is, but you can take a section in and they should be able to match it. I'd like to know what size it is for future reference.

I can't remember how the sprocket is attached to the rod. Is it on a key or what?

I've looked for good diagrams for the chain system, but haven't found any ...

Have not taken mine loose yet but as I recall my looksee the sprockets are keyed on with allen set screws, but I would not swear to it with out looking again. They should not be too hard to pull off in any case. I am sure sprockets would be available as well. I would find it hard to believe that Trojan had custome sprokets made. The gear box at final drive to the rudders looks like a recirclating ball sector like used in Chevies.

Did all the F boats (and wood boats?) through the late 70's or early 80's originally come with the chain drive with rods and the 90-degree gearbox at the starboard corner?

Mine came with the hynautic steering and its an 84 F36, model 460.
