Two older postings suggest at least a couple Nic 38 builds had Forman steering (which Adrian described as a “cheap copy”), rather than Mathway Steering.
The Nicholson 38 manual in section 3.D. Steering Gear says:
The steering gear is by Mathway Marine and is the L.S. Type
My question is – how do you know you have a Mathway steering, rather than a Forman type?
Does anyone know whether some Nic 38s were built with Forman steering, or maybe an owner replace the Mathway with a “cheap copy” when a repair was needed?
I did a variety of Internet searches for Forman steering gear and could find nothing.
Thanks – Marilyn
There’s a picture of a Foreman box somewhere, the differences are quite distinctive
I will try and find the picture

This must be a Foreman box as the Mathway one is through-bolted to teh mounting whereas this one is just mounted using the bottom plate, round top rather than ‘curvy square’, different end stops & doesn’t have a locknut for adjusting the preload on the gears (to remove backlash)
That’s extremely helpful Guy, thank you. Now I’m thinking ours is the Foreman type – here’s a picture of the aft gearbox still in place. Photo taken from the aft deck locker.
Anymore advice you can offer greatly appreciated, you seem to know a lot of about steering gear.
I’m reaching out to @jonathanc (Jonathan Carr), who wrote that FB posting, in hopes of learning more since he obviously had his all apart!
That certainly looks the same as Jonathan and it doesn’t match the Mathway drawing.
To have the amount of backlash that you have in yours, my guess would be that a bearing might have ‘let go’ or something else has happened to move the gears apart (the only thing that causes backlash)
I don’t know anything in particular about these boxes, only that it’s very similar to the pinion & crownwheel of a differential and I have rebuilt a few of those due to years of owning various Land Rovers
I updated our progress in another posting. I’ll leave this one to be the discussion of Mathway vs. Foreman steering boxes.
