Marina motors are not as strong as sprite motors in standard form. Crank
and rods are weaker, pistons are lower compression than most sprite
motors I think.
HOWEVER, since the marina crank has 2" big end journals, they can be offset
ground
to create a stroker motor that uses Cooper S rods. With 73.5mm pistons you
get 1440 instead of 1380. If you nitride the re-ground crank it is pretty
good.
