hey guys
i just bought a yamaha 4 stroke 15hp out board last year and now are looking for some upgrades that might give it a bit more power i am not interested in buying a new motor at all because i only use it 6 weeks a year and i have to carry it my self so a 20hp 4 stroke will be to heavy and 2 strokes are out of the question as they will be banned shortly. but any way i have herd that the only difference between a 10-15-20 yamaha motors is that they just have different throttle limits and that they have smaller or larger orifice in the carburetor so i am just after some clarification on these. is this true? if so can you direct me to a website or store that might be able to do this for me or give me instructions so i can do it by myself
thanks Alec
