When I started racing, I had a Janz D Hydro that I bought from John Brusk. Wil Pergande had originally ordered it but then decided on CSH and a DSH so John got the combo C-D boat. But I never talked...
Ron, I laughed at running a C motor on a D stock hydro. When I started playing with C, my first chance to test and race it was up at Wakefield on my D boat. I tested a bunch of props but didn't like...
I'd have to agree about the handling of the 45 being worse in handling on a hydro going into the corner but I think the gearcase was the main factor. The motor had the propeller quite a ways rear of...
As I remember, Jerry ran about 89 with the 45SS motor and his EMH was noticeably faster. I had been bugging him for some time to let me have a ride in the E and finally in the fall at Kaukauna, he...
The 1970 Chicago PRO race was going on at the same time as the Stock Nationals in Beloit WI. I was pretty new to racing and had a horrible elimination heat at Beloit in DSH so when I missed out on...
Ron,
If your dad inspected at the 1954 DePere stock nationals, did you go with him? It was my very first boat race. I could ride my bike to the pits, maybe 10 blocks from our house. BTW, I learned...
Its pretty easily to visualize why this wouldn't work. Imagine just two opposed cylinders with the rod you desire. It will fit together when the cylinder pair is at TDC-BDC and the rod is straight...
I remember seeing a pic of experimental Merc opposed 4 built with 2 cylinder KG-Mark 20 type blocks when they were contemplating 40 hp engines types. I can't remember where it was- maybe in the...
Let me throw out a thought or two on ignitions. From the time we were playing with Merc V-6 tunnels running the same style ignition used here, we found the surface gap plugs would have a high speed...
Your studs/bolts should be fairly easy to remove since there is so much of the body above the block. My wife likes PB Blaster so use it after heating the bolt and boss. Let sit for a day and try one...
We always use 1/4 inch pipe threads with a #6 AN fitting and cap on Yamato stuff. It's quick and easy to remove the cap and attach a cooling hose to test wheel. Best pics I can find quick.

You are comparing apples and oranges. You should have run the Phelon mag and found where it sparked with the timing light and then set the OMC to spark at that same point. That eliminates all the...
I remember as a kid going to a race on Lake Mendota or Monona in Madison W I and smelling the horrid smell from someone burning the teeth off one of those phenolic gears!
The reason I asked you about the water pressure issue relates back to Jeff Lewis running a 2 liter (122 cu inch) V-6 Merc on a hydro with a similar pick-up. He was in the 130-150 mph range and...
Thanks for the update on the carb preparation. Wish I could go over to see it on the 18th but plan on being at the World Championships in Lake Alfred FL that weekend but I'm sure I'll get to see it...
I've looked at pics of the carbs but still have questions. The pics show the main bodies with a hollow trunk in the center of the float bowl. On that trunk is a threaded hole on the thicker boss on...
An inside caliper works well and can get around and nozzles or tubes in the venturi. It is an indirect measurement like the snap gauges so you set it in the part then remove it and measure it with...
Fred certainly did the engineering of the project, but I like to think that Bill Chatfield did the mechanical work and made the Wizard a reality. A bunch of us took a side trip to Bill's shop one day...
If the Arcadian guys could adapt 2 Merc V-6 powerheads to a champ mid-section, putting an offbrand V-4 on one should be doable.
Mercury experimented with numerous lower unit designs in the Quicksilver era, including some extended prop shaft designs for straightaway records. Del Snyder has a poster of maybe 10-12 different...
Must be fun to drive with all the slack in the steering cable shown in the above head-on shot.
Any thoughts on possible water pressure issues with rudder mounted water pick up at 130 mph?
I do...

Here is the way we do it. This particular motor has a fuel pump so there is no tank or bracket to use. Note elbow on one hose to direct water discharge out for better visibility. Hoses...
The black wire with a yellow stripe is the ignition grounding circuit. Connect that wire to ground and it shorts out the ignition. Since you disconnected it it the motor and the ignition works, the...
Bogging when the throttle is advanced is a symptom of being too lean. That could be caused by the card itself being lean on the low speed or it could be because an altered intake lets the fuel falls...
You want both compression and low port timing in a st0ck powerhead. That is easier nowdays with line boring but back in the 70s and 80s it wasn't difficult to find a block that was factory machined...
Actually the secret to a C Stock Merc block is very simple. Pull the intake port covers off all your 4 port cover blocks and pick out only the blocks that have the intake ports milled or drilled the...
I bet a lot of those thicker driveshaft housings were peinted white and had the water line exiting out of the exhaust relief hole!
Sorry guys, 57 Fords with 312s were turds. I had a 57 BelAir hardtop that originally was a light 6 cylinder car. I scrounged up a 57 Chevy 283 and trans and never had an issue with a 57 Ford. Of...
As a boat builder who is always looking for better handling and cornering, the FE boat we won a couple championships a couple years ago used a pulse tuning pipe which has all the attributes that Tim...
eLove the neat work and thought involved. My question is why is the adapter plate so thick? I don't know if I'm missing a good reason since in my mind lowering the heavy powerhead an inch or two...
Not sure why you're running R plugs unless its necessary for some of your electronics. The R plugs are more fragile and will fail when overheated.
I hope the plans to run some of these motors at one or more midwest races pans out. I am especially curious to see and hear a stock 75-H run. It probably has no unique sounds like the alky jobs do...
Or if changing jets is illegal, you can always resize your existing jets. I'm sure they could have been damaged somehow and you were simply repairing them. Stupid rules are excellent ones to work...
Just go buy two diodes- 600-1000 rated volts . Total cost under $2. Hook one end of each diode to the coil wires and the other together and hook an ordinary kill switch to the paired diodes and...
I think you'll like the Schaeffer synthetic oil. We've used a number of their products with good success. We don't see other boats with Schaeffer stickers on them or others who are even aware of it....
Boy, I just played a bit with a friends 140 that had some issues with transition from idle that several experts diagnosed as problems with labyrinth seals on the reed cages. I had some 1500XS reed...
As a kid I used to play with Mark 20 Mercury motors before I knew much about the race motors. I cut the exhaust snout below the cavitation plate off and then lopped off the end of the main tower...
and he's not far from US Chrome
There are also 2 different exhaust tuners for 15hp motors. They are similar in length (from memory) but the older one is a smaller diameter. If you gotta buy one get the newer one. If you scrounge,...
Play with the timing, stock carb jet is probably too rich, plug water outlet from powerhed into exhaust pipe area.
A Milwaukee area company is announcing that it is going to be producing a 557 hp outboard motor. It is a V-8 based on a supercharged 6.2 liter Cadillac CTS-V motor. Company headquarters are nor far...
A real KG-9H has an AC mechanical fuel pump which is driven off an eccentric on the idler gear between the crankshaft gear and the one on the magneto shaft. I had one as a kid- #406743- and cracked...
With a little trig you can see that the distance from either the bottom of the clamp bracket or the bottom of the boat back to the propeller or whatever you use as a reference point is dependent on...
We did play with the SST-90 way back when it was new. We eventually did add 2 barrel SST-140 carbs but it was simpler to just add a V-6 powerhead than make adapters to fit on the little block. Why...
For most HP, you gotta give the nod to the Hauenstein brothers and Bill Chatfield for their Wizard Merc. They put together an OZ class motor that was so fast that OMC quickly moved to have it banned....
In my conversations years ago with Bob, he said that they had enough dyno horsepower to go 200 but the powerband of the motor was such when they put on a prop that would theoretically go 200, it...
It's all about leverage and mechanical advantage. Putting pulleys on the steering bar with the cable end anchored to the cockpit side will slow the steering down by 1/2 but it will also decrease the...
Harken makes a pretty complete line of hardware for sailboats and has some for wire. We use 3/32 7x19 SS wire on smaller CSH-CMH boats and don't use coaming pulleys at all, just a Delrin block. They...
