In the past days a discussion began about
the reliability of 27 Alpha, because what I can read I can say for sure
is not true, I'm forced to write as follow:
The current crankshaft has been released,
after I've used it for a complete race season, at the end of 2013. In
all 2013 and 2014 I had no one stop in a race due to an engine problem
and it is very easy to check that I've won almost every international
race I did.
When I did not win, an other 27 Alpha has won.
Of course the engine must be properly used,
unfortunately when I'm at the international races I don't see many
drivers with a proper use of a racing engine.
Said this, the only problem can occour now
on 27 Alpha is that the crankshaft can easily move out of line after a
crash or a dive. Source of problem could be the carburator that is not
easy to set up, I'm working on this.
Last consideration, I've seen there are
still many of the old crankshaft, I've changed two complete for free to
two customers at the W.C. in Dessau. My question is: why this if I sent
to the dealers for free many of the new ones?
Closing, C.M.B. never kept out of sight, if you have problem just contact us.
Until mid August the M1 - tuning kit for 27 Alpha the price is 250,00€
at the public. The price for distributors will be communicated via mail.

INFORMATION 45RS !
INFORMATION 91RS EVO !
The 2014 engine has a new crankshaft and front housing. If you use a
shaft that thrusts on the engine you need to order from your dealer the
version with the 2013 front housing and spacer.
The 2014 91 EVO has a new crankshaft with a larger crankpin 9.65mm
and one extra needle roller in the conrod which has a larger bore. The
crankshaft has no step on the front. The front housing has a bigger
12x32x10 ball bearing. This bearing does not have a circlip to hold it
in and bears directly on the front crankshaft web. This makes the
crankshaft more stable. It is available in geared and direct drive.
Because there is no circlip holding the bearing, boats that thrust on
the engine like hydro’s and boats with flexi drives need to add a
spacer on the crankshaft and use the older front housing with the
circlip holding the bearing in. This will loose the advantage of the
closer bearing to the crankshaft but you will still have the larger
