Trolling yamaha sws2

 Hi, my old boat had a 4s but the new one has a Carburetor'd Yamaha salt water series 2 V6 200 2 stroke.

my questions is for anyone with the same/similar 2s motor, if trolling for periods off time are the plugs likely to foul up (like on a dirt bike) or is this a non issue on these motors?

also what could I expect my fuel economy trolling around 7knots.

If it's the oil injection setup it won't be a problem. If you're trolling it drops back to about 400:1 . When you give her a handful you'll find that the rate will go up to about 50:1 . I ran my 90 Yammie like this for years with no problems, never fouled a plug.
