The 33S877-0014-G1 further supercedes to the 33S877-0019-G1 Which also has the 9 amp charging system same as the 33S877-0043The direct replacement is 33S877-0014-G1 But the 33S877-0043 PTO ends are the same would with some possible mods the mower side. One would be a change in the wiring for the lights as 0043 has a 9 amp alternator and the current engine a dual circuit alternator. The dual circuit has both an AC output for the lights and a 3 amp DC output for charging the battery and other electronics. The 9 amp system would only have a DC output that must jumpered the the lighting AC circuit. Of course the lights will then have a switch to them
The problem there is PD cancelled my account due low volume of sales. After Briggs filed their bankruptcy sales took a dive here. Before there was lots Briggs to repair now it mainly Kohler and Kawasaki.What happens a lot is Power portal will show a replacement engine, but when that replacement engine is put into PD to order they come up with their own thing and supercede to another engine.
Thank you for the responses. I was able to get the proper engine and appreciate your inputBlown engine on 2014 model with 33R777-0003-G1 B&S 18.5hp. What is appropriate model to replace it and where would I find one in Michigan? Would 33S877-0043 found on Amazon work?
