This mercruiser 350 has 300 horsepower at 4,000 to 5,200 RPMs. This is the same 350 mercruiser engine that will save you lots on fuel usage and is the perfect replacement for 200 horse power 230 horsepower and 260 horsepower. There is no converting because all the differences are built inside the engine nothing changes on the outside. If you are replacing your factory 5.0, 5.7, 305, and 350 mercruiser engine this 300 horsepower is the only way to go it is built right here in our factory US MARINE ENGINE and you get a gasket set to install all your marine parts from your old engine core. You can also replace your 5.0 or 305 with this 300 horsepower 350 without any modifcations. Looking for even more power install our 6.2 350 horsepower Mercruiser engine and again there is no converting. No matter which mercruiser engine you pick we use all brand new marine engine parts. Yes true marine engine parts cost much more but they are better and last so much longer and lets not forget more torque. Don't settle for a cheep engine it will leave you stranded on the water with a very unhappy family and soon to be old friends.
