I have a 1996 Evinrude 50hp 2 cylinder outbaord that has fouled plugs 2 of the last 3 outings. The engine runs superbly until I lose one of the cylinders due to a fouled plug. The fuel/oil mixture is at 50:1. I use the reccomended Champion plugs. I use very inexpensive tc-w3 outboard oil. The size and pitch of my prop. is geared for top-end speed not acceleration and works well for my typical 2 person light load outings. The particular 2 of the last 3 times I took it out in which the plug fouled I had the max. amount of weight on my boat and really put a load of stress on the engine. Questions: Should I use NGK instead of Champs.? Should I buy more expensive tc-w3 oil? Does the high pitched prop and heavy weight, which probably limits rpm's affect any of this? Any other reccomendations?
