Omc Ft-10s

[brichter]

I am looking for any info on these OMC race engines such as photos, tech info or specs sheets. I have most of the parts for one of these and I think I am going to put it together in as close to the original configuration as possible.
For those not familiar, FT-10S is the designation for the 3 cylinder, 49.7 ci motor that was approved for the UIM SE class around 1968. A special mid with linkage on the side was used to adapt the 14:23 GT115 type lower unit. Pictures of the hood graphics, dressed powerhead or shift linkage would be especially helpful.

Hope this is helpful.

Hi Brichter,

I use to own one..a Johnson..More or less a stock 1968 55hp power head
on a special mid section.
X/GT 115 hp gear case and the shifter on the side of the mid section..

Ft 10 S used the standard transom brackets and no power trim..

1973 OMC came out with a better one..Named 65 SS

A modified stock 65 hp power head..different cylinder head and exhaust ports..

Same mid section, gear case but factory power trim from V-4 racing..

I won the 1973 European SE Champion ship with that engine..

Maybe have some better photos..

This is my 1973 lower unit, but FT 10S look the same..

On the right side of this photo you can see a FT 10 S mid section..

Repainted in Johnson Stinger colors..

Regards

Thank you for posting those Sam and Lars!


Lars,When you say the standard stern brackets do you mean the aluminum type used on the service motors at that time (like the orange mid in the picture)? My mid has that same type but I am not sure if the FT used those or the steel GT115 type bracket.
Stock 55 hp powerhead is what I figured was used. Do you remember if a flex flywheel was used on the ft10 s?
Thaks again!
