Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
Engines will last as long as they are taken care of and maintained, they also last longer the less they are beat on and less of their max power band used. Engines can last a long time before rebuild and or replacement is needed depending on how their life has been on them is what I mean. Some people may say 600 hours other 1500 others different, everyone will give a different answer, I try not to give numbers because of the above I explained. With that said one can tell a lot of mechanical ability by checking compression and listening to how the engine is operating, temps, rpms, speed etc.
Thank you!
