coolest looking v-4 crossflow?

[Bill Gohr]

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,

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?

Thanks

[Bill Gohr]

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.

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

This was off Starflite IV

That was used on the original runs on IV, the last runs used a newer motor going back to a single megaphone.

Anyone got a parts breakdown on the x115 gearbox?

Not the full breakdown but hope this helps.

[Mark75H]

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.
