K&B 16.4cc

[John Seybold]

Hi, I have a K&B 16.4cc outboard and was wondering if any has run one of these motors. I have a 7.5/11cc tunnel hull that I planned on using. This should work ok, right?

whats the tunnel lenth and make ??

Its 34 inches, roughly the same size as my Aerotech. I cant recall the make of it, I purchased the hull and the engine in 1994!!! I had to double check because on K&B's website its states the engines were released in 1997. Must be a typo on their site.

It should work I have a 11cc on my aerotech tunnel runs very good. I don't see it being a problem as long as you set it up right.

My first build was 50 inch tunnel with a K&B cube. Hull was far from suited, I'm sure the Aerotech is a much better option.

The main problem I found was finding a prop that would utelise the torque of a cube that wouldn't be too harsh on the flex shafts.

Still managed to see low 50 mph with the massive tunnel I had, no pipe.

I still have a couple of the cube outboards, will one day get around to doing a similar project.

This will be an interesting project, keep me posted.

I think it is build by Jerry Dunlap.

I used a ABC H7 and a 1450 Mod Prop and it worked pretty good. Aerotech are good ruff water boats not good for top speed a 40 inch woodstuff would be better add a tuned pipe and you can modify a lawless lower unit and it should work perfect and be very fast. Depends on what you wanna do lol.

Thanks everyone, sounds like it should work out ok. I'll keep you posted when it hits the water.

Got some primer on it, sorry for the poor pics. Any idea what brand? I purchased it in 94-95

LOOKS LIKE A HTB 360 1ST GENERATION I MIGHT BE WRONG

 

[John Seybold]

Still think it will be good for the cube?

 

[julianconde]

yes it will my friend it will be perfect

 

[julianconde]

yes a one cube or even a .67 will work on it also

yes a one cube or even a .67 will work on it also

The tunnel pictured looks like a Tri Star. If the hull is epoxy and the right sponson is deeper than the left, it is most likely a Tri Star. The Tri Star was a very good boat and ran in the high fiftys twenty years ago.

The hull is all fiberglass, what would be a good prop to use with this engine? K&B recommends a P-260, however Shoboat doesn't think he will be able to get one, and ideas???

P260's don't fit on standard K&B lowers (diameter to big for cavitation plate, not sure why K&B recommend the 260 on their website?).

A P255 will fit fine.
