Hi Dick
ages ago I was trying to find that rotary load cell kit I knew they used on Class 1 offshore boats in europe, not sure who supplied those
but I found an old Hot rod 2013 and...

when you have a strange problem with a Merc, swap out the stator

its a great effort and it will be an engine remembered for a very long time

whats the yellow material?

Yes being able to put the engine under load in the shop is a big part of it.

Hi Dick

I was wondering if you are able to get the load cell set up so that you could put it 1' from the shaft centre to enable direct readout?

Which OMC's make 3HP /CI? the factory race engines are 2hp ish /ci

I wasnt looking for a friction brake just an easy way to measure torque on a spinning shaft.
Perhaps using gears is a better way to get your 2:1 load?

OK I will try to find it. I do remember seeing an article about the supplier for Class 1 offshore a few years for the European racers. I was sure they said it was an eddy current device so it was the...

Perhaps one of those onshaft inline eddy current load cells might be an easier way to measure the output.
They used them on one European offshore sterndrive class to allow a power to weight...

where is the load cell, on the pump or reduction?

The stator has both batt charge windings and coils for charging the ignition system

What oil did you use?

efi engine running on your dyno is what we were all waiting for

happy new year
hows the dyno test coming?
and the EFI?

I believe this might be Jon Wrights dyno?

I dont fancy trying to dial in an il6 with adjustable jets, thats a double handful there, adjust 6 and get them the same.
6 egt sensors?
I guess if anyone can do it you can.

very nice!

personally I wouldnt dead head it
run a fuel manifold for the carbs, have the fuel return to the tank and get the type of regulator you can install on the return line.
but before you spend the...

run it under load at night, its amazing what you see

you need a plug reading peak voltmeter to see what happens to the plug voltage as the load comes on
Run it open circuit to see what reserve you have
Great troubleshooting tool
We had them in...

adjustable makes for quick adjustment as its development engine
more engines blown up by electric fuel pumps than 100% reliable pulse pumps IMHO ( saying that they dont work as well at big revs so...

Have you considered a test prop?
can use in the shop in a tank but also at the race site

wow

on what brand are we talking Fred?

I agree but always wondered about Merc using loctite and OMC oil?

Dick
You might want to get some bolts and do some torque to stretch to see where they stay elastic so you find out the correct torque spec regardless of what Merc say
At least you can them check...

crank pin offset?

wow
Thats got to be close to 250hp potential there...

I see the logic, thanks
I thought the issue to get over the increased rig groove clearance in a keystone is the acceleration of the piston will push the ring out as it sits on the sloped groove?

lol

whats the reason not to go with a keystone ring?

200 xs ssm 6 is right in and left out if you want to go new.
Use a v6 race flywheel and starter and run the engine ccw?

looks very cool now...

Fantastic stuff
The pictures dont give justice as to how many hours went into all that.
Well done

typical of an engine that comes apart every day, oring and copper?
