Nope, no problems, I only run super unleaded in it anyways. Runs really well, speedo is reading 71mph and gps says 67 mph top speed. How inaccurate are those Speedo‘s typically?

thanks

I think that magnetic fields can confuse the exact location of GPS

The gps is correct, the paddle wheel is off. My 12f routinely read 70mph.

My speed is down around 6 mph, clearance gap is .018, dings on prop, scratches on the inside of housing. I've attached pictures. Is it necessary to replace the housing and the impeller?
