..,Pretty common idea in the sterndrive arena for years prior(and after) Bern. Not too marketable for the consumer O/B market. But could be, for large O/B's, in the future. Racing...yes.

That's what I used for my prototypes - all MerCruiser stuff. Used the Merc 3.4 hollow lower transom bolts to run fluid thru the transom from reservoir to gearcase. A must for big OB's but what did I know, I was just a field guy that was in the Florida big boat builders every day!

Bernard...You probably utilized the lower mounting bolts/hydraulic fittings, that came standard on the first generation(1976-79) Mercury V-6 O/B, in Figure 1, Item 15A, above. They were still available in the early eighties. Maybe you came up with the idea in the field as an answer to the first generation 3.4 gearcase water intrusion issue, that was found to be caused by a water pump base design, that leaked? Mercury updated the 3.4 water pump design two or three times in the first years of the consumer 3.4's.http://www.mercstuff.com/images/reservoir.jpg...along with the 70's/80's MerCruiser drive reservoir bottle...?

Seen those plumbed into the 70- early 80's MerCruisers going to the vent plug.

Was this back when synthetics were new or was it a specific brand? Gary

HA! I worked a kid at 16/17 a gas station after school and remember when "Mobil 1" hit the scene! $5 a quart (in 1965ish).

OK, ya right as after Nam 69! Maybe..But it was the 60's/70s and all a foggy time life! Rest still figuring out! "I was there, but when?..dunno"!

BUT? I DAMN sure remember as the owner station had just bought a new 1965 HD Duo glide. Maybe not Mobil 1 but the first syn oil new. Never forget it.
