Main jet change on a 1995 30/40 EHO

[Bald Paul]

Gentlemen:
I'm a first time poster here and was wondering if I can change my 1995 30 HP EHO and bump it to a 40 HP with just a main jet change.
Thank You
Bald Paul

No, it is NEVER a change in jetting that increases the HP, there are other differences in the motor that require the different jetting.
