What gives the 130 the 15 more horse's?<br /><br />I don't think the stroke and bore is bigger so, it must be in the carburation and electronics. <br /><br />Is it just the power pack or what? Anybody know?<br /><br />Thanks,<br /><br />GG
There are several differences, Bose.<br /><br />With the same displacement, on the water performance doesn't show much change until you get into the max rpm range.
Same stroke and bore between the two.<br /><br />The 130 hp increases compression (about 5%), raises the operating rpm, and makes a few carb changes.<br /><br />I'd have to look at the parts book, but the compression increase probably includes different pistons and a slightly different head design.<br /><br />Torque X RPM / 5252 = HP. So an increase in rpm will generally increase HP if the Torque doesn't drop too much. The compression increase keeps the torque up. <br /><br />I've had excellent luck with the 115.
