I'm going to rebuild a carb and water pump and want to be able to tune the engine in the basement before I do a decarb on the lake. Can I properly tune a '82 35 hp short shaft tiller evinrude with muffs or do I need a tank? I don't mind building one but would need some help with the dimensions that would allow me to run at WOT.

Thanks!

No you cannot run at over fast idle speed on muffs. To run at full throttle in a tank would require a professional tank at least 4 ft square, baffled, and vented with a super large blower. And a test prop. That is 35 snarling horses you are messing with there.

Best start it on muffs to make sure it runs, then head for the lake.

Not to mention the fumes. Not exactly conducive to healthy living. Get it to your shop, lake or outside but not in your house. Rick.
