Thanks, but all I need is 1 case to make a motor whole. Ray

mecoa lists different part #'s for the ib & ob cases. i've got A LOT of 3.5 k&b stuff. got the parts mostly in parts/box lots. have enough parts to build 2 rear intake motors, and about 3 end covers with no pto. but, ALL the cases look the same :blink: ? who can tell me the difference, and does it matter if you use an ib case for an ob, or the other way (ob for ib)?

No difference whatsoever. Outboard will work just fine.

[moparbarn]

do you know why they carry different part #'s on the mecoa site? hey ray, call me with your addy, i'll mail you a christmas present. hey, got all my distilling done, this flow meter actually works on boat motors, too :lol: :lol: ?

 

[topfuel443]

Because they are K&B and part numbers are very abundent around that area...?

I honestly dont know. Maybe there is a difference that I didnt see. I could be wrong, but when I held them up together, back to back, there was no difference...

~James

 

[moparbarn]

i've looked and looked, i cannot find any difference, either......

 

[John Knight]

When I was running K&B inboards and outboards at the same time, I interchanged the cases with no difference in appearance and performance. I suspect it is a scheme by K&B to sell more parts by listing different part numbers for the same unit.
