wtb: lower units for outboard

[Jesse J]

so... I have this lower unit and want to run twins. If somebody has an identical one/two of these for me... lets see it. I may be wanting to do triples if I can get two more for decent price.

One question: what is max rpms these guys can handle? I was wanting BJ motor (1500 KV) on 4-6S? (that would be possibly 30-35K rpms)

What kind do you have already?
I dont know much about OB's. Are they the same as a nitro lower end? If so i have a K&B, but its a 7.5???

Steve.

[Jesse J]

I remembered I forgot to add photo... Don't know the name of it - I think its K&B - but maybe pic can help.

It was for nitro. This one has a conversion and I will have one showing up that has a nitro engine that is supposed to be a super good running set up - willing to trade for lower unit from one that isn't so good.

I would like to track down two more of these if possible

[Chuck E Cheese]

those are k&b legs... i just sold 2 brand new for about $50 on iw
you can get them here for about $70 with stub and flex shafts

Hey Jesse,
It's a K&B. I converted a 3.5 K&B for my Bud Light with the stock BJ motor. Ran it a lot this summer with a x437/3. One day I tested some different props and ended up braking a flex cable with a Prather 215. The boat was torx rolling out of the turns when ever I would hit the throttle. It would put it up on one sponse. I think it can handle the RPM's though I only ran it on 4s. Hope that helps.

[Jesse J]

thanks guys - this is totally new water for me, but I have always liked the look of outboards and want to trick the Cyclone with three of these babies!!!

Any more info/links or if you have one, hit me, I wanna get this goin!

[Jesse J]

I would even take somebody's that the engine is bad on...

[Jesse J]

anyone?

[nomobux]

anyone?

Just a idea .. Maybe post it up in the RCU nitro boat forum. Has to be alot of old KBs sitting around in boxes.

[Jesse J]

Yep keen thought. Just found a pair for $70??? on the first page of the FS forum!!!

thanks, AND I am still looking, will close this thread if I find one elsewhere.

Steven, Did Hyper take care of the issue with his OS mount being too short??? Also his coupler does not work well with the stock OS Flex. I recommend one of the Hyper flex shafts as part of the package. The stock flex is a little too long plus it will also spin inside the Hyper coupler.

He was supposed to send replacement mounts to those that ordered from his web site but I havent recieved one yet.

I wasnt aware of the exact problem. But I was told to return what I had and i've received the replacements.

Jesse, I just wanted to let you know that you can cut out all of that exhaust porting on the lower halves of the K&B (Kaboom) lower end...it will save you some weight! When you get those lower haves check out the insides...you will see the porting. If you're not sure what I mean, check out an OS lower and you will see the shape of what the K&B should look like if you cut out...just make sure you don't cut out where the flex runs through...

You will need to buy the K&B P/S assembly...not sure what/if anything else will work...

I would not use the stock OS Shaft for anything, it will spin inside all collets as it has a smaller square with rounded corners
