Keep us updated Joern!!!
Impressive ingenuity on many fronts-

Joern,
Ok, then I know what brand this is. Yes, it is for 67 for sure. Actually I have 2 of this pipe, except the other one is a few mm shorter...Joern,
You have to be really careful using the Cooper pipes on the larger engines as the additional back pressure tends to make the 67 and 91's run very hot. You need to get that heat out!!! Nitro pipes with "no resistance" stinger mufflers, or the free flowing carbon pipes work much better for these larger engines. If you could carefully remove the muffler can from that pipe, and add a stinger muffler, you might be onto something!!!...Make sure it is a 67 size pipe first!!
Joern,Jeremy is presently working on a 67 carbon version of his pipe for this new outboard engine. These pioes I have found work the best on all outboard size engines and will be the same for the 67. I invested in a large "lot" of initial pipes to get him to make the investment to take on this project. I should have the initial pipe order around the first of Sept and will carry them in stock just like I do for the other size engines. They will be in stock soon.Ok, then I know what brand this is. Yes, it is for 67 for sure. Actually I have 2 of this pipe, except the other one is a few mm shorter...I`ll probably try it out and see how it works. Just ordered a pipe from Joe, with a stinger muffler. And I sent a request to Jeremy Wooster in case he want to make a 67 pipe now when the Nova came on the market.Joern,

I opened the engine yesterday, and by the first view it looks like a nice engine.
Will be interesting to see how it performs on 25% nitro.
Brad,The initial design utilizes the same crankshaft as the 67DD. To make this possible, Nova designed a screw-on flywheel that tightens as the engine is cranked and is further secured with lock-tight. As this class continues to grow and volume supports further design changes, a completely new outboard only crank design will be considered. Keeping the number of additional parts required to create this engine utilizing existing 67 DD parts is what helped us bring this new 67 OB to market, ( only needed flywheel, PTO housing, and OB PTO shaft). This design also opens up many other possibilities. Could retrofitting some of the newly designed 67 OB parts to use on the 91 DD help create a 91 OB as well??????.......
Nice Randell. Enjoy!!!
