Luis..............I re powered TAMZIN several years ago with a BETA38 and could not be more pleased with the outcome. Probably the biggest asset to the installation was having Bud right there instructing me on what to do. After 90+ installations he's got the procedure down pat and there were absolutely no problems. No problems means less cost for the installation and in the long run. For your guidance all in the price was almost exactly $15,000, but that was for everything from the engine room bulkhead aft. New engine, fuel tanks, shaft, cutless etc, ect., as well as the very minimal cost for having Bud there.
