Re: Alpha 1 power
Something in your post has me confused, a standard 5.7 liter (350 ci) engine is rated at 260 HP, the magnum should be 270 or more...not the 250 that you described. If you are reading the boat manual...forget it, call mercruiser with your engine serial number and ask them what that engine puts out. Regardless, you most likely have a fairly fast boat that is dependable. If you start messing with the engine without taking everything else into consideration (read replace, also read high $$) you will most likely end up with a boat that goes a few (3-5) MPH faster and constantly has problems. Enjoy what you have, keep her tuned up and running top notch, and when you need more speed, move up to the next best platform (engine, drive, hull).
