Nova 46...good info to know

[Glenn Quarles]

are you guys using the flanged or un flanged bearings?

On my 45 boat I am using 4 unflanged. Two right next to each other towards the front of the stub shaft and 2 next to each other about 1/4" in front of the drive dog.

On my other boats I have used a flanged bearing at the very end in front of the drive dog. I have seen no difference...it just depends on how you want to set them up.

thanks Glenn!

Glenn are you using .150" flex in the 21 & 46 or some thing different. Martin.

Unflanged no-name for me. I think NTN makes the bearing size tho.

 

[David Bryant]

Glenn/Guys, these are the timings i got Novarossi to do(everyone might come up with a very slightly different measurement):Main exhuast should be 189

sud exhaust should be 186

opening on crank 210

closing 69

boost 134

transfer 132

head volume .40cc

carb bore --11mm (.430thou)

regards Aaron

just curious, how do these parameters compare to other popular .45 marine engines (currently) on the market- ie. Picco .45 Blue Head, A/A .45, CMB .45 VAC Blue Head, etc.,...?

interesting, 4 bearings? What is the length of your strut tube/housing?

David, all 4 bearings fit in about 1.5". I have 2 bearings right together, then about a 1" brass tube spacer and then the other 2 bearings.

What diameter flexes are being used on both the .21 & .46 motors. Martin.

Martin, I use .187 on both.

Martin, I use .187 on both.

I take it that these are the welded or brazed flex & stub,where their both the same diameter ie 3/16". So the stub cant be bored for the flex to go in as their both the same diameter. Thanks Martin.

Can anyone provide the Top of Liner to Top of Piston Measurement. I would like to put it in the Engine Analysis software.

Marty, I used the EAP to get all of the numbers I posted, but I don't remember the measurement. I can post it when I get home.

[Martin Hamilton]

Glenn do you use the welded/brazed joint on the flex & stub joint because the flex is the same o/d as the stub. Martin.

Martin, yes.

So any one measure the OD of the liner or the wrist pin dia or is this top secret?

Are there any parts available yet? If so the price?

Guys, I just got home from the big Christmas road trip and am trying to get all the orders packed up. They will either go out this afternoon after I get off work or tomorrow.

I have a few motors left.

Thanks!
