The 'hate 2 engine is junk. I've worked on to many. They are still junk. They quit making them 15 years ago. Best bet REPOWER. A bit costly heard around $14K for the job, mabe a bit more. Might be better looking for an older coach a bit larger but with a series 60 engine. Way bigger and way more power. Keep looking. REPOWER , do not get a reman engine from ?????
