I am getting ready to buy a 125 evinrude motor for a 19 ft bayliner center console.I just wanted to know where i can buy an extension to convert the lower unit from a 20 in. to a 25 in. The boat requires a 25 in. motor,i have heard that johnsom/evinrude are the easiest to convert.I appreciate any and all feed backs relating to my post. THANKS,DSOLO
