Retail pricing for the Yamaha XTO 425 will start at $44,250 for the 25-inch shaft in right rotation and $45,185 in left rotation. The 30-inch shaft will retail for $45,000 (right) and $45,935 (left).

Yes, this is from 1981 and Mercury made very good props. You needed to modify the rubber hub to solid. I dont think its a quicksilver cable steering. (Pretty pricey overseas) Teleflex in Sweden made a similar for a better deal.
Back then OMC did not have counter rotation as an option.
This was also the first year for the 2.6 liter cross-flow V6. (235 only)
I sold a ton of them.

they did have the fwd only left hand box, when did that come out?

We never sold any counter rotations without reverse. Maybe some aftermarket stuff/or Second Effort 1983 and later.
The first counter rotations we OMC dealers could order was 1985. The one when the powerhead was run counter and a new gear set/drive shaft and much more. (Looper V6/V8 only). Took forever to turn a standard to counter. Lots of problems and finally we got the real counter rotation gearcases from OMC a year or two later.

for the xflow v6 they had a neutral and fwd box so fwd was aft in the box to suit std rotation engine
Its in the accessory catalogue

I heard of that on the early Mercs but not the OMCs.

I had an early V-8 that spun backwards.
Wierd.
Different starter and seems like a cable running around p.head to advance timer.

We did many counter like that and I think the V8 was running smoother the other way but a terrible kit. Many hours to install and it did not fit so good.
Extremly hard to get parts for. That stupid cable around the powerhead was a disaster.
Nope, we stopped installing them.

you could order ccw v6 v8 from new I thought back in the day?
Then later just the lower changed

[lars strom]

Well 1985/86 and 1987 OMC sold a counter rotation kit for the V8.
Second Effort sold engines they installed the kit but Limited Edition model and cost way more money.
1988 was the first year for factory counter rotation from OMC.
Finally the new gear case was available
First picture the kit, second the new gear case 1988.

That the typical outboard dealer only stocks their inventory with 60hp and below these days. A 25hp long shaft costs more than my limited production Merc Twister did in the 70's.

[lars strom]

Well..yes but very few new larger outboards are sold by dealers today. New outboards are mostly sold by boat factories under long contracts.

Outboard dealers can only sell to the re-power market.

I got the first counter V6 lower made in 1980, it was as mentioned a forward neutral only. Here in the USA the first 160 inch 235 was 1980 not 81

First, yes you are right..1980 not 1981 for the thin sleeves. Thanks for correcting me. We had a lot of problems with the early 2.6 cross-flow. Cracked sleeves/blocks.
Well.. never heard of a counter rotation production cross-flow V6 gearcase from OMC with no reverse. No way you could sell that in duel installation over in Europe.
Did really OMC build/sell that??
