OMC A Foot in 25 MOD

[STEVE FRENCH]

If you run 25MOD (or thinking about it) and need a foot, you might want to look at the OMC-A foot. I ran one several times last year and it worked well.

It was very easy to adapt to my Bayer tower.
The gears are bigger/stronger than the Merc foots. Ratio is close so you can run same or a little larger wheel.
I never saw a drop of water in the oil!
Will try without impeller next. Pumped plenty of water with it.

Best part----they are now available from HOT-ROD! (Sutherland/Seliwatch (sorry on the spelling Ron)).

OMC foot legal??

Steve,

I thought the only two boxes you could run were the Merc A-B spec and Hot Rod? Did that get changed? I haven't run the class in several years and may just be out of touch. That would be a logical rule proposal though if it isn't legal now.

Steve,
Last I knew, any foot that met the R/S specs was legal.
The A-OMC foot is perfect, strong, and will even fit the stock OMC 22/25HP tower with a 1/4" plate/adapter. You can take a 25 OMC "fish'n motor" and in 2-hours have a legal A-MOD, (closed exhaust thru tower,)
OR add a pipe and have a legal 25MOD!
I have one with stock cowling and a bayer pipe that is .......

Will post pics ASAP

25 mod gearcases

Steve,

I just checked the tech manual and the way I read it you are correct. It must meet the R and S as well as the gear ratio. I think it covers all three. Between Hot Rod, Merc and OMC that is quite a selection. Hopefully others will see this and realize that there are more options. I never realized that the OMC was a 14:19 ratio until tonight!

Steve,
The OMC-A foot is basicly a new style Hot-Rod foot cast with provisions for exhaust and to bolt to the OMC factory tower.

VERY strong and easy to adapt to other applications.

For the 25MOD/Bayer tower, I left the water tube-OMC adapter plate off, This leaves the top area of foot flat.
This tower had a large pad on bottom that covered all six of the foot mounting bolts. slipped a 1/2" drive socket over the drive splines using a socket who's O/D came close to the tower drive shaft tube I/D. Made the socket fit snug in the tower with a couple wraps of electrical tape and pushed the tower/foot together to mark bolt patern on bottom of tower/adapter-plate mounting pad. drilled and tapped holes. drilled and tapped water passage to match the foot. Ran water to back side of tower with a couple 1/8"npt fittings and 1/4" fuel line, plugged the bottom of the original water tube with a slug of silicone seal and --Race ready!

Trying to add pics as soon as I figure out my new Kodak Easy Share camera.
May have to consult my 5-year old step Grand-Daughter---DOH!!!!!
