|My trusty old Walbro 6805 which will be retired into backup status.|
I replace the 6805 older model with the newer FRB13-2. Interesting to note that the 6805 was rated only for diesel fuel, where the FRB13-2 is labeled for all fuels, including ethanol and all biodiesels. Since I run biodiesel, I'm happy about this, though I never did have trouble with my 6805.
The swap out is easy, and even the mounting hole patter is the same.
While down there I also replace my exchanger zinc. Ever since putting a spacer between the transmission and prop shaft I have had much less rapid corrosion of my exchanger zincs. It is now electrically isolated from the shaft, salt water and propeller. They last about a year for me now, and at that time they are only about half gone. A nice interval.
