Please my friends can you sujest me the diferences of the engines ?
What would you chose between the 2 engines???

Many thanks

Top picture ... RZ254 Evo.
** Fits into mounting position within boats rails same as the Side exhaust engines using like type mounts.
** Has a rope starter
** Has flywheel forward at starter end same as side X.


Bottom picture ... R254 Evo.
** Cases more compact requiring RCMK's own rail type mount system or custom mounting.
** NO rope starter requiring belts and electric starter ( Like Nitro engines )
** Flywheel at PTO end limiting how low you can mount engine in a flat belly hull.


If racing within NAMBA ?
RZ Evo a legal G1 engine
R Evo a GX1 engine

The power is the same?
Many thanks

Yes for the most part, tho the RZ having the angled intake tract is a plus over a straight in like the R for case filling efficiency and likely has the edge if we were spitting hairs
