I finally deleted the email but about 4 years ago I get an estimate from Jasper's to remanufacture my 235 - complete engine - for approx $1800 plus freight. That freight can be quite a bit for something that heavy unless you get it to one of their authorized dealers.
Jim Carter advertises they have 235's rebuilt but I think their lead-time is out 2-3 months.
