I am rebuilding my 1988 1140cc 90 HP Yamaha outboard.
I have been researching on here and talking to local shops to see what we can do to boost the performance just a little while we have it tore apart.
Here are a few things I'm considering
Boyeson Reeds
Tuner
Hydrotec performance head
Re-jetting
Will most likely do Boyeson reeds and tuner, maybe the head and jetting with time.
