All good information is helpful Jeff....
....even if it's not what you thought at first, it could keep you away from a dead end. Nice looking boat, & good job of refinishing. Looks like a little too much fin though unless it's a long straight with tight turns.
Turned out I gave some bad information myself. I had thought I did a kilo record and a competition record with 41994 in the same year. That was my goal, but it didn't happen. The competition record I set in 1976 was also with a Marshall Grant motor, but it was the double rotary valve "F". I have to spend a little time getting all of this straight because I lost some notes and my files are all scattered.
Marshall didn't keep notes on serial numbers and I don't think many people do. I did through part of my racing career and quit toward the end, but I would never remember a number in the wee hours of the morning from any other motor we had unless it was the "Donald Duck" motor. The fact that the number was so unusual and that we spent more than six weeks trying to figure out how to correct this perplexing high speed miss must have ingrained that number in my brain from writing up so many test sheets.
Just a thought............
I know you said you were going to display this engine, but just in case you get the urge to hear that sound and smell the castor..............
Does it have retainers w/loose needles on the wrist pin end or caged needles?
If option #1, change the retainers and spacers!! (If not all the bearings top to bottom.) The only tough one to get might be the split center one, but I'm sure there are still some around.
I can appreciate your thinking Jeff....
....but this ol' girl has come home to rest on a red wall. If I cranked her up and tore out a chunk, I would have lost some of the magic.
It's not the old style crank, and short of tearing it down where I can get a peak at the pistons from the backside, I'm saying they are the caged needle bearings. As I turned the motor there were no slight tight spots, stickiness or anything that felt like the bearings were bad or gummed up.
However, the bearings for the rotary valve belt are another story. They look like the same ones I last laid eyes on. They need to be injected with that purple stuff people take to loosen up their joints. But I am glad to have them as all they need to do now is provide tension for a replacement belt. I will have to find one of those. The one that came with the motor would only come down halfway down the top carb. BTW, what plugs do people use now. Are AC M40ffg's still around? I have no plugs either.
So I guess the plan is to get an incense pot. Fill it with a 20:1 methanol/castor oil mix. Light it off. Pop a top. And sit back listening to the Marshall Tucker Band while looking at the motor.:D

I've only seen one myself Roy...
...and this is it. VF7023. It was acquired from Marshall Grant at the same time as the D motor. There is quite a history behind it also and like the D, it went to Harry Bartolomei, so at one time it was in California. Don't know where it is now.
Marshall brought some of the first, if not the first, square block Konigs to the U.S. As far as I know the first square blocks were built in 1970, or maybe being cast in late 1969. Maybe Sam could help us here.
I don't know if any other double rotary valve konigs exist. This one has another rotary valve and set of carbs on the exhaust side. The block was cut away and this rotary valve was mounted offset, slightly higher (may correct after I see the photo) than the other rotary valve. This is because it runs the same exact belt as the front side rotary valve, but they run on the same gear--one belt above the other.
The primary problems costing a race were two. Blown lower unit and losing one rotary valve belt. Belt problems normally occurred when the motor was started. If it happened, it would be one belt popping. Once the motor was running, it was surprising how few belt problems there were.
As one pit man learned, don't look into the carb on the exhaust side when Jack squirted gas in the motor to start it. You could see clear through the motor on the carbs where the valve was open. If the gas didn't hit the crank, you would get a shot of gas in the eye.:(
As I research the D motor, info on the DRV F pops up so after I get down with this I may post some more stuff on the F. I keep finding things I forgot about. Here is a photo of the F. I was just looking at this pic to try to figure out which motor on the rack was the D.
Celebrities in boat racin'
How bout ROY ROGERS winning the long beach (or where ever) to CATALINA RACE in a yellow Jacket molded plywood boat with 2 mark 55 h's on it ? And Guy Lombardo in his (Tempo ? ) unlimited hydro ?
350 Hydros? What About 350 Runabout???
Seems to me California lost three 350 drivers from "Blow Overs"...but can only name two...Ray Hoot and Shawn and Spencer Love's dad...Both were testing when they got hurt...
Why not a NASCAR page.... Big courses, Prop Shaft 2" below the bottom (Works like a carb restrictor)... Under 3/4 mile 1 inch below the bottom...
I believe that the 1 3/8 transom height has made "A" Stock runabout and hydro safer....but at speeds of 57-58 now in "A" Hydro, I would not consider this a "SAFE" Class...
The next class to have major injuries will be Super E....or what ever they call the class that runs the three cyclinder OMC.....Those suckers are going over 100 laying down...
I know we say it is racing, but we could require reinforced cockpits in both hydros and runabouts, we could require a side height in runabouts. We could have breakaway noses and pickleforks....
Do restricted "C" Runabouts have less accidents in 25 SS Runabout than they do is "C" Runabout??? Personally, I'd rather run a lower transom height, than lower power, but I like the restricted concept as it has worked well with J, AXS, and A in Stock...
My HOME DEPOT ONE DESIGN would have the concept of new boats every year.. Build it for a SPECIAL RACE...play with it after the race...next year build a new one...
The Solar Boat Racers have to buy a bare hull each year as part of their entry...Maybe sell a simple "KIT BOAT" laser cut by like MJR Boats... with theyear laser cut in them...
How about, for DePue 2007, we have GPS Trials for guys that ain't still racing...like "Fly Bys'???? Or will you not want to fire that "D" Konig once you get her rebuilt???? I do think we should have a boat show there....
