I have a johnson 250 v8 no id plate and numbers on the core plug that makes no sense. the cover is red and gray with a horse head decal on the cover. also cream color center section.Its a 25" shaft. Can I make it a 30" by changing the center section, extension to the drive shaft and shift rod?? Is it timing and carb jet sizes that differ between the 250 and 300hp. t' Any guess as to the year thanks for the help
