Hi i got a dirt cheap pipe from ebay (where i get most of my stuff) i got it because it is light, and i want it to go into my 40" drag boat project ,i would like some help to identify what make it is as the seller had no idea, i took a risk buying it, but as i said i got it dirt cheap, its the one in the first 2 pictures ,(engine without a clutch) I also have a 67mm brass prop, i am unsure what make it is, but was told it was an octura ? would that be ok to use in the 40" boat and using an anti torque strut ?? The other 2 pictures are of the engine and exhaust set up i will use in the cat if i ever get it built .

Hi Rick,

is it S. steel or aluminium?

the first one is aluminium, i would like to find out what it is, and how it will perform on a standard zen 260 pum with a modded 644 walbro , the other one is stainless, heavy and very quiet unlike the ali one

MrMikeG

Looks like an Older Irwin nitro pipe but I could be wrong. The steep rear cone will make it more RPM specific but I'm sure it will tune if you take your time.
67mm Prop doesn't tell us much, I would guess it is a 1667 because that is very common, if it is it is a good hydro prop but needs work for a mono or cat. Mostly it needs to be spooned to take the lift out. Very Wild ***** guess though! [8D]

Believe It

pipe kinda looks like the Bonzi quiet pipe

MrMikeG All the prop has got on it is 67 the rest of the numbers look like they have been polished off ? I was told it came off a vee, and my drag boat is a vee so i hope it works ok.
Believe It, the pipe might be a Bonzi quiet pipe by name ? but its not quiet at all [&:]

heres some blury pics of the prop, it might give someone a clue to what it is ???

Believe It

does it look like the numbers were ground off before or after the 67? I have a 1667 and my mono didnt like that prop for nothin.

rickburnout666

It is before the 67 but i cant really see if it was numbers or just rough moulding, the prop has been polished and needs polishing some more . i`ll just have to try it in the boat and see what happens,

MrMikeG

What size is the hole? If it is 3/16" it could be a X467, it's not a 1667, sorry for mis-leading you. X series props are good V or cat props. I think you will want something bigger though.

Anyway Rick i want to know how your gonna shoehorn that zen into your drag boat?i bet its a tight fit?.I agree that prop looks like an x467 should work ok id try it and see you can allways get a larger one if your not happy,on the octura chart its rated for a zen!!.

rickburnout666

MrMikeG, It has a 1/4" hole for the shaft.
martno1fan, No shoehorns needed, yes there is not much room, but enough room for the 260 pum, its not like putting a 28cc weedy engine in and whats the worst that could happen ?? anyway i like diving it could be an octura prop as the strut, and rudder i got it with, are octura.
