    I have a 1760MT Lowe Roughneck with a 4 stroke 25hp Mercury. I have heard that by changing the jets you can make it a 30hp. Is it worth the time and $$. Would gas milage offset performance? Frog Legs

    I don't know about Mercs, but I've got a late '70s Johnson 9.9. I've always heard that all you had to do was put on a 15hp carb...Then while researching it, a mech told me you had to change the reeds also...Seems that alot of people just change the carb, some say it works, less say it doesn't...I haven't trimmed it out on the latest boat yet so I don't know...
