I have found a 14 hp motor to replace my 16 hp. The 16 hp was Mod. 311777, Type 0209-E1, Code 011211ZD. The 14 hp replacement is Mod. 287707, Type 0224-01, Code 97011ZD.
So, the replacement is a little older, but said to be in good shape. I cannot locate much on the web to compare the two models, I can only find info on the newer motors on the Briggs site.
Any opinions on whether or not the 14 hp is a suitable replacement to the 16. I can't get the 14 hp till next Monday.
