evinrude 140 on 16' tahiti HELLLPP!

Also check your primer that the red level is in the right direction..

[joeymcgovs]

i believe it is the correct gear case beacuse it has a 13 spline prop shaft, i believe the v6 gear case is a 15 spline prop shaft...

what should my tach be set at? on the back of my faria tach there is a dial and has the settings here is a pic

[H2OPERF]

tach should be on 6 poles or 12 pulse per rev, i think the 140 came with both cases in some years but the large case model has a diff ratio than a v6 case , so you have a13x19 not a 14.5 x19

[mrichartz]

This is for a 92 so find out what year.. has throttle body #s to reference..

[mrichartz]

And this is 1990...
Attachment 492808

[joeymcgovs]

i cant see your attachment for the 1990, but the numbers on my carbs are as follows:

carb body: 398743
2 screw plate on side: 432903
float bowl: 333525

all 4 carbs have these same numbers, when i look these up on marineengine.com it comes up as a 1990

the throttle plate housing numbers are as follows:
top of housing: E334872
bottom of housing: MX334872
throttle butterfly: 332250

my tach is currently on the "5" setting which i believe is the setting for "12 cycles" there is also a "6" setting but doesnt say how many cycles that is?? not too sure about this

[mrichartz]

So looks/sounds like its a 90.

Was looking thru the piles of jets that i have.. ive been going thru and finally organizing them the idle and int are just to hard to see.. need a damn magnifying glass.

[joeymcgovs]

i had to use a magnifying glass too haha
so i guess the jets in my carbs should be: 54, 41, 63D in all 4 of them

i guess i gota start looking for 4 - 63D's for the high speed, i already found 2 - 54's for the intermediates, just hope this is correct ��*♂️

[mrichartz]

Boats.Net should have them.
its literally the only ones i dont have any left of all..
Guess 140 jets were in demand beginning of summer sold all i had thought i had more but. Definitely did want to sell them all

[joeymcgovs]

its strange how the models after 1990 seem to have different jets on different sides, i wonder why they did this?

[joeymcgovs]

do you know how to adjust the float height? i have rebuild kits for the carbs on the way and i want to make sure the floats are at the correct heights

[mrichartz]

Just flip over to see where they are and just bend them..

[joeymcgovs]

ok ill try that but im not sure theyre adjusted correctly now

[mrichartz]

ok ill try that but im not sure theyre adjusted correctly now

Oh the floats in there now yea probably good you didn't het the kits w floats? Just wondering whats in there..

[joeymcgovs]

i did get the kits with the floats
