Thanks,from what Willy at CMI (who also tried the shorties) experienced sounds like a pair of boxes might be what you need too,break out the mastercard,whoever said your kids needed to go to college anyways ,Smitty

Also I was told with the Stellings you have to raise the motor for the box.

You know Smitty, sometimes you just have to be happy with 93 mph! If you keep on people might start being afraid to ride with you.

My boat came with the boxes on it, however,
I've worked on a few with them.

I've pulled the engine, and simply unbolted the
driveshaft flange at the carrier in the box.

And I've replaced a driveshaft through the
side access covers ( yes, you can get to the
crankshaft bolts)

So to answer your question, yes and yes.

But, since you'll have the engine out, connect the
driveshaft to the engine first, then drop it in.

Theres only a few brave souls (and a few not so smart ones) who will ride on the boat anymore .Actually I only go fast when I'm going fast .I had my wifes friend and her boyfriend on boat a week and a half ago,opened it up and trimmed it out to 89 on gps,when we slowed down my wifes friend asked how fast we went,I said 70, she said well that didn't feel so bad. My wife gave me a look and showed me the gps,I chuckled. My stock speedo hasn't worked in years,Smitty

Thanks,thats been one of my un-answered questions. You wouldn't happen to know how long the driveshaft is when actually installed would you? Stellings told me it measures 11 1/4 when fully compressed. Went to local spicer drive shaft shop today with the 34 inch driveshaft and they can put a slip yoke and flange yoke together for me that should compress to 11 1/2 BUT the flange yoke is on 4 month back order in the USA. The next size bigger they could have in a day but it will be 12 1/2 when compressed. What screws it up is these usually have 1350 series u-joints but this driveshaft has 1410 series which is unusually large,Smitty

I'll pull a side cover off tonight and see if I can
get an "accurate" measurement..

Mine are in the middle hole, so I know that they
wouldn't be fully compressed.

Smity I did the same thing to my Girlfriend when I first put the whipples on. I brought it up slowly to 95 with the girls sitting on the back seat and told her it was just 80 . .My buddy told her otherwise she didnt think it was funny

That would be greatly appreciated,its ALWAYS a PIA every time I do a mod. I talked to the osoer today who sold me the box,we worked out a reasonable deal on the driveshat being so far from working. Called Canada trying to see if the spicer dealers there stocked the yoke shat I need,no dice. I'll probably get the longer one and cut it down slightly shorter than your minimum measurement,thanks for the help,Smitty

Measured it last night.
As close as I can tell, looks to be about 12.75"
from back of flange to flange.

Mind you, this was through the access cover,
the tape measure touching the flyweel near the flange.

I would think that this # would get you close though.
