Fast Fred's Secrets of the OMC MOD50's Thread #1

[BRIAN HENDRICK]

This SELVA 850 for sale on a German web site
Some resemblance to a Mod50
What are they derived from?

[Mark75H]

The Selva race motors are based on the Selva fishing motors. Selvas are their own creation, no direct forbearers. By coincidence, Selva started just after Carniti closed up; so it is possible that some of the Carniti engineers may have been looking for jobs when Selva was starting up.

Carniti had triples and prototype 6's that looked amazingly like T-2 Mercs ... before Merc built the T-2's.

at a glance, not lookin like that v-4 powerhead is just guna jump on thare.
but then i did see a v-8 on a merc OS mid and drive, a 20" 3cyl mid is lookin a lot like a V-4 mid, exhaust addapter for sure got to change.

cool a 50cuber F3 SELVA, lookin like port side exhaust, and OMC carbs

The carbs in the picture are OMC, for some reason Selva was never able to make their carbs work and would buy OMC Mod50 carbs for their engines. When Paul Kalb got wind of this he put a stop to the sales.

Hi Jim,

I remember that, to bad for Selva.
The OMC carbs was the only good
thing with that engine!!!

I think the Mod 50-OE-F3 was the best class in Racing with
"production style outboards"
and my best Racing memories is from that class

Thanks Jim for all the good work you did at OMC.

PS. I think they still used OMC carbs for years

It seems to me that they could just have used regular V-4 cabs. Tom Ireland used V-4 carbs on his mod 50 . At the 1976 opc Nats, he said he was using 100 horse cabs , and was going to try the 140 horse carbs .

[Fast Fred]

the main nozzel is too big in diameter on the stock carbs, it Will flow too much fuel.

[Lars Strom]

There was plenty of those OMC carbs around in Europe, and I think the Selva brothers just bought them
from a dealer or Ital-Marine as a carb for the FT 19 S SE engine.

I sold many FT 19 S to race drivers as a dealer, and if I remember right OMC Sweden stocked that model
1978-79.
