    Jetting for overbore

    My rebore will be 15 over and I'm getting conflicting info on rejetting one size up because of the bigger cylinder. Has anyone here rebored and had to use the next size bigger jet? Thanks Tim

    I need to rebore

    I need to have my outboard rebored. Is there any particular reason I should go with .030 over .015? My outboard is currently 75 hp but after thoroughly reading the manual it looks like I may be able to go to 90 hp by putting a different set of carburetors and jets on the motor. Any thoughts...

    Still Need Some Help

    Like a lot other posters here, I'm losing power at WOT. I thought it was a electric issue but the switch box and coils have been replaced. The stator and trigger all check ok on the multimeter.
