I was considering to upgrade the stock Selva Madeira reed valve blades to carbon fiber ones but didn't have time look for suitable replacement blades. At least
Boyesen makes reeds for outboards.
The stock blades are made of fiberglass so I'm not sure if one can see any noticeable difference in the performance after switching to carbon fiber blades. The fiberglass is good material as the engine will not suffer damage in case the blade breaks (same goes for the carbon fiber). In case someone wants to try different blades I have listed the specs below.
Selva Madeira 40/40XS/50 reed valve blades:
- blades are not attached to each other, every blade has it's own screw.
- the number of blades is 12 per reed valve so the total is 24 blades per outboard.
- the length of the blade is ~52.5 mm / 0.55 inches
- the height of the blade is ~14 mm / 2.07 inches
