Re: Nissan / Tohatsu 6h 4 stroke

yeoup, you can get a little more oomph by simply chainging the main jet on this outboard and most alike...

but if one doesnt want to well thats their call huh

in any case, many ways to get a little more oomph

changing to a bigger throat(intake) and changing the main jet acoordingly for WOT or close to it will give you what johnson did back in the 80s and 90s

2 engines in one block

a 9.9 and a 15hp, absolute only difference was this above, throat size, main jet and a few other small things to get about 1000rpm or so more at wot

again correctly prop it for sure...

solas props do a nice job of offering a variety of props for every situation

peace

Islander 36 no longer for sale...its MINE!
