Hi filodore
the first thing you need to look at is doing the nads,youve got a great
motor there and they run well if looked after,it dosnt sound like your
in a hurry to go bush and cross any rivers just now but yes a snorkel
will be a part of your nads at this stage
if i was you id talk to boots and meet up as suggested to get an understanding
of what these nads will do for your rig,they definately do help these motors
but like most things not invincable
