Hi Folks, Building a small FE tunnel for my son. I would like to use a K&B lower and a Lehner XL. I need a 1/8 shaft to square shaft coupler. I have a few 5mm to square couplers. I may be able to use a brass insert to make up the difference, but was wondering if folks were aware of any that...

Hi, I have a K&B 7.5 cc OB 8702. Where are folks getting parts. I need a piston and sleave (I think) and MEcoa seems to be sold out of much of the 7.5cc parts Dave

Hey folks, I have a older 32" Woodstuff with a K&B3.5ss. It seems to run well and have good compression, but the performance is a bit slow. I'd guess 35ish max. I still can lean the needle out a bit (head just gest warm) but the boat is unlikly to pick up 5 to 10 mph Is 35ish the max I'm likly...

Hi Folks, I posted a few questions previously and received responses THX!. However in looking at my Glow Plugs, head and Piston to see how it was burning I noticed something you might help me with. 1) The sleave will rotates. I noticed a notch at the bottom presumably to ensure it is linged up...

Hey folks, I need a little help. I finally got my tunnel in the water this weekend after 2 years on the shelf. The boat started well had lots of torque but did not wind up to full rpm and died after about 1- 2 minutes running. The engine did not seem overly hot when I retrieved it. However I...

Hi Folks, I have a 32" Woodstuff for sale with a 3.5cc SS. The boat is one of the earlier WS boats and is better now for Sport running, not competitive. The boat is immaculate, few minor scratches but only you'll know. I used it for a summer at the cottage and had a lot of fun. Handles VERY...

Hi Guys, First thanks for all the help this forum has been. God knows I've asked my share of questions that makes one go.. duh :blink: ! I got my 32" Wood Stuff with a K&B 3.5 SS running two weeks ago and I was quite surprised how well it ran, especially how well it handled. However I have...

HI, I have a K&B 3.5 SS and a K&B 7.5 8701. I noticed the throttle barrel is somewhat off set to the left on my 3.5 so that the barrel and body does not match when fully open. There is about 1/8 of an inch (That may a bit f an exaggeration) of barrel on the right exposed in the body when wide...

OK, So Ive just about finshed rigging my first Nitro Tunnel and I'm hoping for some advise for the Throttle linkage. I have a Servo in the Radio box (duh) with a wire inside teflon (Sullian 508) to a Clamp at the motor and a Quick Comnnect to the throttle arm. I have it rigged so I can turn...

I was wondering if using CA to glue the motor connectors to the Steering cable is adequately strong for a 3.5. I like the look of cable steering and intend to use a pulley on the Servo with Nylon quick connects at the MOTOR. Any nasty surprises for me with this setup MOTOboat

Hi Guys, Just got my 32" Wood Stuff boat with a 3.5 SS. I noticed the engine mount (OCTURA) is quite sloppy. I have an extra HI-Jack mount and may use that but it may put the motor too high. Any experiance with Octura engine mounts and how the "Fit" the K&B Motor mount pim? MOTOboat

Ok guys, I'm new to Nitro and am trying to learn from others mistakes (cheaper that way) If I had a choice betwen a water cooled K&b 7.5 and a Air cooled (Gold) for sport running which would you recccomend. Advantage/Disadvantage of Water Cooled vs Air cooled..

Just bought one of these of EBay. Price seemed good to me an all I needed to add is a 7.5 K&B and radio. All the rigging had already been done. I have a 7.5 from an earlier purchase. They look nice, now I'm wondering from the lack of people I see on this thread running them, what have I got...

What are you opinions on this hull. I saw one with a 3.5 K&B, radio (Futaba) and a starter got on eBay recently for ~400. I wondered why the hull went for so much with a 3.5 on it. It was pretty, but would it perform? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...AMEWA%3AIT&rd=1 Are ABS hulls...

Hello, New to Nitro, just bought a 7.5 K&B off eBay. The previous owner says it ran and had new bearings installed. In general it looks used but not abused, however when I rotate the engine I can’t help notice some "FLAT" spots when I turn the crank. It is very subtle but I can feel something...

Hi Guys, I'm currently considering purchasing a K&B 7.5 8703 from my LHS. He has it new (Still wrapped) for $375 Cnd. I live in Canada and seem to keep getting horror stories about getting parts for K&B out of California. Can you comment on parts availability and the quality of this model...
