View Full Version : coolest looking v-4 crossflow?

05-19-2010, 06:29 PM
anybody have any good pics of the coolest looking factory (factory race or fishing motor) of the old motors (evinrude or johnson). am painting mine and want it to look very factory and very 1970's, even though it is a late 1980's crossflow.

anybody got any pics of some of the 1970's gold/green v-4 that look good?


the pics above are awesome. where did you get the louvered cowls?

I made the Johnson cowl out of an old 74 115, the Evinrude is original except I painted the top after I put the louver in

Hi Bill
Integral trim and a 135, didnt know they went together.

( Looks good though!)

You are correct they don't go together, that hood I had in the attic for 20yrs. and when Tiger showed up with a blue and white Allison to build an engine for I said I have just the hood for it and I had the side decal made to match the originals.

Look closer, yes it shouldn't have that trim for a 74' Strangler, but the whole engine started as an 86' and it's a 15" shaft. I had my old 78' ph with 77' ignition and a KR flywheel from ages ago so I told John we would make him a custom V4 that may look like it came that way. I made mine out of all different ignition just so I could use the F1 V8 flywheel.

Another year for good looking Evinrudes...it was either '76 or '77 they had two tone dark blue with a red white and blue placards on the sides.

Is there a lot of H.P. difference between that Johnson and Evinrude on the allys? Looks like the prop on the Johnson has a lot more rake.

I like the primer solenoid mounted where the old choke one was...

(see last picture) 245 is Duane Timm and 364 is Jim Umbarger I think.
Those are nice pictures, thanks for sharing them Mark!

I always thought the X-115 was a sharp looking motor.
Here is a shot of one a little closer. I don't know whose boat it was but it was a red Vampire.

Bought my X-115 brand new for $1300.00 and set up a UI rig. My 1st effort at OPC. Boat is a renovated "Sidewinder" I bought as junk and rebuilt with a lot of help from Bob Rhoades and Jim Daniels. Ran well, was US-1 high points!:eek:

Anyone got a parts breakdown on the x115 gearbox?

05-28-2010, 06:01 PM
It was never released to the public. I'd like to see one if anyone has it.

How where they repaired?
Call OMC and ask for parts?
I have a offshore V8 breakdown, I guess they look the same?

05-29-2010, 06:01 AM
It was a simple process ... you sent the lower unit back to the factory, they fixed it and sent it back to you.

When I saw the V8 offshore breakdown with its dual pinion shiftable works, I realized they were probably the same.
I doubt you can do it any other way as compact as that.
The X-115 is certainly long enough for the third gear on the prop shaft and
the double sided main gear doesn't add that much length.

Best I can do is a cutaway assembly drawing, but I will need to scan it.
Should be able to do this soon.

Coolest looking V-4 crossflow was the Evinrude used by Hu Entrop on the Starflite III: no cowl, four megaphones;)

I have the parts list for the gearcase, no pics, back in the day you sent the GC back to service and Larry Overbie rebuilt most of them,

06-07-2010, 06:41 PM
Those v4 units were pretty bulletproof.
My dad used the the same clubfoot for 20 race seasons. He used it most of the races he ran including a few marathons and It was used when he got it. The only thing we ever did was replace the propshaft seal and the lube a couple of times.

Iy appears to be a work of art that remained hiddern for years till the 2nd Effort offshore engine which was probably rarer?

Anyone know where Larry is? When he left Winthrop Harbor he moved down to Kentucky or Tennessee, worked at Birdsong Marine, I talked to him several years later when he called me at OMC but that was a long time ago, thats where all the old Gearcase info is, when you sent your GC back to plant 3, it was him or one other guy that did all the race cases.

Anyone make an aerosol of the orange used on the old stinger gp? If not, what did you do gohr? Did you use a preval and hugger orange?

that was easy, I went to my buddys body shop, he has the PPG paint mixing system, I brought and old Stinger hood, laid all the chips on top of it, added a little for age and it comes out to be I think a Porsche color.

This was off Starflite IV

06-13-2010, 07:42 AM
That was used on the original runs on IV, the last runs used a newer motor going back to a single megaphone.

Not the full breakdown but hope this helps.

Thanks. The shifter mechanism is the same that was used later on the Second Effort offshore motors.

The driveshafts turn a center located double sided propshaft gear for forward. This gear is
mounted on splines and floats back and forth between the driveshaft gears. The torque from
the input gears causes exactly half of the load to go to each side of the gear all the time.

These gears are not directly driving the prop shaft, but instead are driving a tube that
surrounds the prop shaft. At the back of the tube is a sliding shifter sleeve that has splines
inside that lock it to splines on both rotating tube and the prop shaft when the shifter pushes
the sleeve back.

For reverse, the sleeve moves forward, disengages the splines from the tube (but not the
prop shaft) and then engages dogs (teeth) into the back of another gear behind the rear
driveshaft. In reverse the prop shaft and tube are turning in opposite directions.

Great stuff
Many thanks
I guess Charlie S almost had the duo prop designed as well!

Did omc have a spec sheet on kr`s& Kc`s? I have a Kc13r and would like to know more about it i want to trace it back to the factory if thats possible.The info tag says it has a oprerating range 5400 to 5800 rpm did they all run that range?

06-29-2012, 06:28 AM
where did all the knowledge go from the guy that did the 2nd Effort V8 offshore boxes?

10-11-2014, 11:49 AM
yes the KC13R had a operating range of 5400 to 5800 rpms but the one that we ran pushed a 27 cleaver 6200
