RPM limiter omc triple 60hp 1995 BE60TLEOC

[pdt]

Can someone tell what the rev limiter is supposed to be on a 1995 evinrude 3 cyl 60hp motor.
this limiter is same part number for 50/60/70hp models from what I am seeing in the parts pages.
its the limiter with the S.L.O.W feature for over heating limp mode etc.


engine model BE60TLEOC

made in usa not the Belgium model.

I have had a few conflicting stories on what these motors rev out at with standard factory electric packs.

would like to know for sure what its meant to be limited too.


Once I know this, I can try different props etc and get to the limiter.

Just pull your PowerPack and read it... The limit is printed in white ink as is the part number.

Example: 58L is a 5800 Limit and a 6L is a 6000 Limit


By the way, there is no separate rev limiter... It is a circuit contained inside the Powerpack.

[pdt]

aaah so its that simple to find out ?
I didn't know if they were all the same on that year or how to tell etc, but sounds good if it is printed on it.
I do know its inside the powerpack, that just so happens to be sealed in resin so people ike me don't go poking around in there ha ha .

I will be checking mine out tomorrow, I am hopoing for over 6000 rpm preferably 6250 upwards.
ive had the engine at around 5800 - 5900 with a realy crappy prop, hoping to get it ot 6,000 with a 23 pitch !!!!!!!!!!! maybe its very wishfull thinking on my part.

thanks for the info 25xs

well I just looked at the cdi pack and nothing like printed part numbers etc
the only thing on mine is a number 3 up in a corner.
so now I am thinking maybe this year was a general spec for the cdi pack ?
and I cannot find a reference to the rev limit for this year.

I do know that cdi does a powerpack for this motor that is rated at 6700rpm, but my one is genuine omc.

maybe the one off of a sst-60 would work. i think they are unlimited.

[pdt]

hi 75man
what i am trying to find out is what my limiter should be at max, then i can sort out what prop to get me close to it for the best speed.
after playing about making a jackplate with 4.5 of setback i now want to know what this engine should get to regarding the rpm.

if the limiter is 6000 then fine or if 6500 then again fine as i can then see if my prop set up is anywhere near what the engine can get to.

i know these limiters are the same part numbers for the 60hp and 70hp of same era, so should i be expecting a few hundred rpm less being its just got 60 carbs ?

i dont want to be running around trying to get 6250 if the limiter is lower for example,

knowing my luck its gonna be very low ha ha

All the aftermarket replacements for your factory Part No. 585145 rev limiter are at 6700 rpm. Likely the same as the factory ignition.

Run it. You'll feel the limiter kick in when you hit it; no harm done unless you run continuously on it.

I understand what your saying 25xs
but I might be running say 6300 (i would love to ) and the engine has a lot more potential and could go to 6700, then i would be down by 400 rpm , .
last run out i only got to 5750, now if i could take this to the 6700rpm i am down by 1,000 rpm and that is a huge amount left to find.

once i know the true target for the limiter, i can then tweak of whatever to try and get close to it, i would be well happy to be within a couple of hundred rpm to the limiter, once i know what it is.

like you say the after market all seem to be 6700 so mybe i might have to look at that figure.


by the way how quick do the limiters come in once they reach their set level.?
i.e if the engine was revved with a very small prop would it simply stop climbing at a certain revs. ?
if so then i have a old prop i can destroy to get it down to about 10 inch diameter and will lose tons of pitch as well for a test.
(the prop would cost more to repair than its worth at the moment ).

once i know the max revs i will stay clear of it on any lengthy runs for sure.

don't think you can hurt the moter,it's got needle bearing and roller bearing. guess you got the 2.42 gear rato? find some 70 h/p arbs. i run a 13 3/4 dia x 27 pitch at way over 7000 rpms, my boat weights 200 lbs. 6700 rpms wont hurt your moter

[Nason]

Just put a smaller pitch prop and throttle back, you will be able to tell what rpm you are good for when the rev limiter kicks in

Good advise...we run the 56er at those rpm's all day long as well, just with a different gear ratio and pitch that's all.

[pdt]

i will have to give this a try with small pitch prop.
once i know what it will do, then i can try to get the 13 3/4x23 srx to something close to it.

ima75man do the 70 carbs make a huge difference in the rpm ?

my goal is to get this boat in the high 40's . to get 50mph would be terrific, but 45 plus i think is best to realistically look for with this boat..

.

[ima75man]

check out a 70 h/p carb off a 56 inch.

[pdt]

I am on ebay every day looking for a set of 70 carbs for this engine.
2 sets have been on there in the last 7 months, both sets turned out to be same 60hp as mine.

they seem to be rare over here for some strange reason !!!!!!!!!!

only one that are available are very old type with old style choke.

.

[Powerabout]

you will get them I have bought several in the last year or 2

[pdt]

with the 70 carb's is it a case of just larger venture and butterfly ?
if so could I get these spare ones reamed out and make up new butterfly disc's.

or is there other stuff deep inside the carbs that's also different ?

.


.

[pdt]

what year did the 70 carbs come out that would fit straight onto my engine ?
mine is 1995 56 cu in with the quick start choke to the inlet manifold, don't realy want to change onto old choke type.

is there any other engines that use these carbs ? like a twin or bigger that still uses the same part numbers etc, as there just is not any of these around.

.

[Powerabout]

you wont find the same part number as a jet change will change the assembly part and bodies are not sold separately.
The first year of the 56 was a 70 so they have the larger carbs.
Those 1 1/2 carbs are also on the 60hp 2 cylinder and later propshaft rated 50.
There are various designs of the carbs so if you dont get the same type ( as the 56-70) as in all fuel jet or 1 fuel and 2 air jet etc you will be on your own re jetting.

[pdt]

just as I thought
I need to stick to 1993 0nwards carbs from a 70hp.
is there anything at all else that is different from the 60 to 70 ? I have looked on a parts list and I cant find anything other than a carb change to make this a 70 (apart from the decals).
such a shame its not just a jet size , as that would be dead easy to get swapped out.

.

[Powerabout]

have you checked with a BRP dealer that your engine doesnt need the changes that there was to jetting and the tell tale location
There is a service bulletin for it.
If you have access to good fuel I would be shaving a bit off the head and or blocking the idle exhaust relief's as well if you have a light boat and you dont overload the engine...plenty of variables in that...

[ima75man]

maybe find some 90 yamaha carbs. or 50 mariner carbs.

[pdt]

regards shaving the head, that is a no no from what ive been told, no space to shave it ??????? only from what ive been told.
closing up the idle reliefs, yes that would give a touch more compression,around 10psi gain, that would put me around 157 to160 psi as its already
close to 150 psi when checked warm with throttles open fully.

the model I have had the tell tale moved, mine came from factory with it at the top and not on side like older models.
its the same as produced right up intill 2004.

ima75man
what is this about using 90hp Yamaha carbs ? do these bolt straight on ? and the mariner 50 !!!! I thought they were even smaller than mine ????
