My dealer wants to replace my 3 yr old 14hp Kawi engine on my 48" w/b with an 18 hp Kohler Command engine with electric start. It is about a year old and came off a scag w/b. (The guy upgraded to a 25 hp Kohler) My dealer said the 18 hp Kohler Command/w electric start cost about $2000.00 new. He said he heard it run when it came in and it sounded good. He said he would put in on my w/b for $700.00- $900.00 parts and labor. Does this sound right or is he pulling my leg. Thanks for any help.
