Just had a long conversation with Ken Welter (Arlington Coot). In
fact, he has had good success with his nitrous assist. The only down
side he sees is availablility in remote areas. He uses it for a few
seconds to get up on the step only. If he is in rough water and wants
to further shorten the run he will use more. With this duration he
gets roughly 30 take offs. This is provided by a 25lb bottle (10lb no,
15 lb bottle)

Apparently NOS sells various jets identified by hp increase. He first
tried the 30hp jets but settled on the 50hp jets which increase his
rpm by about 500. In addition, he carries a set of 80hp with him
incase he gets into a small lake and wants a bigger kick.

He is running a 52 weber side draft carb, distributor ignition
ontrailing plugs, MSD on leading. He has ported his engine with a
modified bridge port something like Atkins uses.

Because of various gear reduction drive problems he has gone to a cog
belt setup which he likes.
His next venture is to link th mazda via sprag clutch to an additional
100 hp snowmobile engine for use in take off or mazda failure only
(he'll shut it down in cruise).

Seems to me that Ken would agree nitrous provides good bang for the
buck. He had no concern about it hurting his engine.
