Driveshaft/midshaft in a bob

[catfish4767]

My driveshaft sticks out about 2" from the bulkhead on my bob. Is that normal? The engine coupler butts up right next to the midshaft coupler and the plate holes aren't lining up. The midshaft that came with the hull is 7" long. The midshaft from my SN is 6.75" long. Should I use the SN midshaft? Does the driveshaft poking through at 2" make a difference?

Thanks

Here's how the shaft looks

Yes thats correct as long aa its a sj 07 and under itll work

What about my midshaft? Should I use the one out of the SN? I feel like I've seen posts where that one womt work because it too short but the midshaft that came with the hull seems too long

my bob gen 1 had a bob specific shorter mid shaft..... idk if 2's have that or not.

and i believe SN midshafts are longer than rn arent they?

 

[bobob729]

It shouldn't be to long i had a gen 2 bob one and one way to find out is put ur midshaft and pump on if it feels good use it

I don't think the bolt patter from the sn will work. Mine uses an rn midshaft. No mods at all.

good god, this aint rocket science! if you used the pump out of a 90 - 2007 SJ, then thats how far the shaft sticks into the engine compartment. that BOB uses a 701 and bigger mid shaft housing. any SJ midshaft ever made is the right one. the midshaft may need to be pressed in or pressed out of the housing to get the gap between the couplers lined up when the motor mount holes have bolts in them.

The midshaft housing out of a 90 sn womt work though its to small of a housing

when the motor mount holes have bolts in them.

That's the issue, the holes don't line up

i have seen issues where the bed plate holes have to be hogged out for them to line up.
