[RobertDoak]

Hello fellow tunnel boaters....
Today was the day I drove out to the Delmarva model boat club in Queenstown MD. to test the WOF Tunnel...i will post a link if your interested..the boat ran well...needs zome adjustments and some prop selection...i used a x440/3 and the rains came to prevent any further testing...

Just a fyi....i took the engine off and found that I had a very large blob of silicone in between the header and engine....the silicone sealing ring used was not an exact fit and I attempted to "fix" the issue... Well it ended up blocking the exhaust so a reduction in power will follow..
I have several on order, I dont know how to size these so I ordered several different ones...
