I am the new owner of an E27 #428. She has an older 15 hp Johnson outboard and I am looking into replacing it with a newer 4 stroke. I am looking for something quieter and cleaner. I have visited the local marine stores and I am told a new 4 stroke of about 8 to 109 horsepower would provide about the same power as the older 15 hp. As it has been explained to me the horsepower of the olde models was measured from the drive shaft but new regulations require the horsepower to be measured at the prop. The effect of this is that my 15 hp would probably be rated an 8 or 9 hp under the new method. Now it is possible that I have a stupid new boat owner look on my face but is this for real?
Also I have any number of reconditioned used (2 to 5 yeas old) engines on the market. Any experience with purchasing used engines?
Finally, Iunderstand that the E27 has a hull speed of about 6.5 knots. Is 15 hp (or 10 with the new measurement) an appropriate engine for the boat. Thanks in advance....
