Evinrude 3836M 1968 - short shaft driveshaft length?

Hi everyone,
I have a 1968 Evinrude Yach 3hp, model 3836M, serial number B9145, manufactured in Bruges, Belgium.

The motor is currently fitted with a long shaft (48 cm. I want to convert it to a short shaft for use on a small plastic rowboat.
When I disassembled the extension section I found that the driveshaft is one single piece with no coupling in the middle.

The driveshaft is 98cm has splines at both ends.
My questions:
1. What is the correct length of the short shaft driveshaft for this model?
2. Is there a specific part number for the short driveshaft?
3. Is it possible to simply cut the existing driveshaft to the correct length, or does it require a replacement part?

Any help would be greatly appreciated. The motor looks to be in excellent original condition and I am looking forward to getting it running again!

Thanks in advance
 
You must have the rare 15" extension kit.----I likely have a driveshaft here but shipping would be an issue.----Local machine shop might cut it and use a coupling.-----Or machine a new spline.
 
There isn’t something like a universal spline one could use? This has been sitting in storage for likely 30 years. I have no knowledge what so ever but it starts and would be cool to use it again.
 
Reading their shipping requirements, they only ship to US customers, but that would be an easy work around, ship it a third party shipper and forward it to Sweden. Probably cost more than the driveshaft but outboards are sunk cost anyway so who cares?
 
Do you know anyone in the USA? Have then buy it & ship to Sweden. I’ve had parts sent to hotels in the USA, had one of our pilots pick them up & bring back.
I looked it up, to ship from Canada is about 470 Sweden krona

If the OP wants to proceed,I’ll contact Racer for the part & get it shipped, along with any other bits he may need. I’m assuming he can just cut the water tube.
 
Small update. I’ve tried to ignite using the flywheel and putting the spark plug on the motor and got a nice white/blue spark. I’ve disassembled the pull-start-thingy and cleaned it from grease and whatnot and preparing to re-spring it. Found a helpful video showing the procedure. New string is purchased as well.

Slowly moving forward and hoping we can find a shaft that fits.
