I have a 52" exmark TTHP. Model # TT5217KAEC Serial ~498000 This mower HAD a 17 hp Kaw engine FH541V-AS24 which ran at 3200 rpm. Today I replaced this engine with a 19 Kaw, FH580V-BS25 which can run at 3600 rpm. Will I cause any damage to anything: spindles, pumps, etc. by running 400 rpm faster than my other engine? I'd hate to govern it down to 3200 rpm, but I don't want to damage anything either. Any advice would be great!
