On Jun 7, 2006 I signed a P.O. for new machinary to build hardware, engine parts and even barstock props.
To make a long and painful story short, I signed the final acceptence papers on June 11, 2007.
So, with that said we are finally getting some new parts made.
This week we have completed a run of rudder assemblies and blades.
We have a broader range of blades available. 0.9" X 4.4", 1.0" X 4.4", 1.0" X 5.1", 1.1" X 5.1", 1.1 X 5.6",
and 1.2" X 6.0".
Our blades are made from 7075 -T6 which has 90% greater yield (bending) strength then the 6061-T6 commonly used by other hardware manufactures. This allows us to make thinner blades.
7075-T6 is triple the cost of 6061 and is much tougher to machine resulting in a higher cost part, but the performance improvement well justifies the extra cost.
Our pivot and transom bracket is also lighter due to the use of stronger material.
Replacement MAC 21 rods and P/L assemblies should be finished by the end of June. The new pistons are from 30% silicon barstock. The con-rods also feature a new design.
I took some pics today and will get them posted at cmdracing.com in a few days.
For those of you who have waited long and patiently, I thank you.
For those who have been waiting long for engine repairs or other work, I will soon catch up with the back log.
Again, thank you for your patience.
More to come!
Good boating,
