Thanks I'd like the hear about this, I just picked up that Evinrude 75 short shaft so looking to learn all I can

ok then, blocks, i know of two styles, plain, wich would be just alu' . the other would be coated or vulkinised with ruber compound, the coated ones seem to offer a better seal.
the block it's self IS a limiting factor, wich is to say once you've maxed out the air and fuel that can pass through the block, you will not make any more power.

Any way to rubber coat aluminium reed blocks?
Can you mill a reed block from rubber/plastic?

[Boatnut]

so i have a spare block to play with, and i have been scratchin my head about the vulcanized rubber bit. seem to me that opening up the block a bit would have to be doable but fer me the dilemma has been replacing the rubber. can i clean the rubber off the block, open it up a bit and mount the fibre reeds onto the bare face? or will the pistons be feasting on shattered fiberglass?? OH gunna be watchin this thread, great topic!

The non rubberized cage's have allway's been used with good result's.
After a period of time the rubber coating on yamaha's will crack anyway.
