If you go through the old Boat Sports you can find some info on them. I have a photo of one of their...

The 1955 Hot Rod had the longer driveshaft housing (1") and dual cavitation plates.
The '55 had the angled spark plugs + no spray shield.
The rope plates are slightly different. Photos by Russ...

After I typed this I went home and looked at at a Mark 6 Phelon Flywheel and it is different, hub is shorter and slightly smaller with smaller crank taper.

I have a very small amount of gaskets...

Alan,
You can use Merc Mark 6 flywheels on these smaller Champions, should be a direct fit if I remember right.

These powerheads were run on Champ 6NHR towers and American Hot Rod towers for APBA...

Yes,
I can answer most questions on the Champion stuff.
The little champ is 9.66 cu in.
Champ made 50 4MHRs in 1953.
Then they made some 4MMHRs in 1955

The stuff you have was probably used for...

Thanks Sam! I am quite sure mine was a 48-28718 Mercury 75H prop.
Had the flat trailing edge like a cleaver. I did not write the number down though.
I have a Merc/Kaminc "D" wheel hanging in the...

I use to have one of those 75H props with 1/4" pin hole.
Sold it to the Snell's way to cheap according to that Auction.

Dave, thanks for the reply. I was looking for the height for current APBA 3/4 under rule.

Cooper

thanks to all for the info

Cooper

I am considering raising the transom height on my D stock runabout to run a Mk55H engine as opposed to a 44XS.
Does anyone know what height I should make it?
I don't know the angle right now but...

Also remember that Champion had the about 15 cuber "A" engine designed by this time.
They had built 3 engines at the factory. Chances are this engine would easily run with a KG4
racer. What do...

I ran across this photo of My A/15 MD built Craig Craft.
This was taken in early 1974 at Ocoee Florida

I bought Mark's big A hydro in 1973 at the Utah nationals.
My ex-wife Christy bought this boat from me and I later rebuilt it and it made a very good 15SSH boat. (I ran this boat at the 77 nationals...

The Yachtsmen's Association of America was accepted as the UIM-affiliate in the USA.

Does anyone really know if the Mercury 25H powerhead was ever made even as a prototype? I was told the test engines went out with 20H type powerheads. And the reed port spec on the 1958 APBA spec...

According to what I was told by Bubby Cartwright of Mercury, they had the prison machine shop make the two Rotary Valve 20H big Bs, 22 cubic inch.

Bill,
I do not see Dee in the picture. I think that is Mark? somebody next to Heberer.
Tom Kargus is right behind the engine. Pat Quigley and Mitch Sears are in one of the pictures.

Cooper

Memory shot!
Sam, I see you, Paul Pittman, Mike Crawford, Tom Kargus, Bill Heberer, Del Snyder (with Kid Kraft cap) Skip Sheleski, Mike Hoffman, Kevin Komorowski,
Len Gerritts?

Mark D,
How's my memory? Did you drop a cylinder (ignition) after the final heat at Bakersfield or was that Hansen???

Fellow competitor,
Cooper

I raced with the Hawkeye group some in the late 60s, early 70s. Had a blast
with them. They hosted the 1972 SO Nationals at Cedar Rapids and also the 1978 SO Central divisionals if I remember right....

Have not followed this post everyday so I do not if any posted about the origianl wood they used. Speedliner made their own plywood and advertised it as Philippine
mahogany. This is not currently...

I had hernia surgery 6 weeks ago myself (umbilical hernia)
and had a rectal polyp removed at the same time, 2 for 1 sale.
So I have an idea how you are feeling. Just behave and do what the doctor...

I remember Hank Menzies telling me about some of his Dental patients
looking at him funny. Seems the inside of his nose was blue from painting the trim on his Hammercraft boats. I got to race...

Bill,
APBA stickers were done this year. Jeff Williams has the Mod Outboard ones and Ed Hearn has the stock ones.

Cooper

Ron,
The VHS tape has not been converted yet. I do not have the equipment myself and have too many projects going right know to deal with. I will dig out Hansen's contact info and send to you.

For Tim Weber:
Gerry Hedlund won BSR at Beloit and I think Clark ended up second. It was not a clean start and it was hard to tell who was running out front. Vic Brinkman was defending champ from...

Dan,
Sometimes the older runabouts had a brace built in for the bottom fin, usually a block of wood between the center bottom stringer and the next stringer to the left. Check if your boat has one....

I believe there was 36 BSRs in 2004.
