rev limiter on omc 3 cylinder ? seems it can be done easy

[filthy phill]

For anyone else who needs to do this I have just asked on another forum about removing the rev limiter from the cdi pack on my motor.
( I have also asked all over the internet too, and a few local shops near me that re-map auto stuff).
I was about to let a local electrics bloke attack my spare cdo to get rid of it, he told me it will be easy once he got to the board ????

I have the cd3 stuff 1995 with the square cdi box.
so many people had told me this cannot be removed and that you need the older electrics blah blah blah.

well it appears that it can be done and very simply by cutting into the two orange wires from stator to the power pack.
the orange and orange with black get opened up and this takes away the rpm limiter and f.a.s.t (quick start) function.

I asked about it being switchable and the answer was yes.

so put the wires on a switch and you can start with F.A.S.T and then once warmed up and the timing drops simply turn it off and your unlimted for rpm.

this to me sounds a very simple process and saves changing out lots of expensive electrics and saves a lot of time and effort.
so all those with the oval port can now go and rev to the moon without costing a fortune.

this I have not yet tried but will be definitely giving it go over the next couple of weeks.

seems to good to be true, but have been assured by a nice clever man that it will work.

if anyone knows otherwise please let me know.

Worked! Cut 2 orange wire, 7400rpm with my testprop boat on trailer.

So you now using later electrics on this ?
What happened to old electrics with unlimited powerpack

[hupiveneilija]

Yes.
Lost spark on 1&2.

[filthy phill]

its good that the newer electrics can be un limited. it gives much more availability to the more modern engines.

it is good you can make your other electrics unlimited, give you much more scope to use anything, plus it is newer wiring too.
saves a lot of time and messing around changing stuff out.

have you put it on a switch or just cut the wires completely ?
I will switch mine so I can use the quickstart feature when I first start up and then when warm flick the switch.
also good if I want to let someone else use the boat and keep them to slower speed ha ha .

[hupiveneilija]

Took pins out of connector.
Mine dont have quickstart, its ovalport feature.

[filthy phill]

I thought the 56 from about 1990 had the quick start !! maybe not.

as long as it runs good and still charges battery , to be unlimited is good for top end.

my motor us definitely limited big time, I think its around 6100, as it wont go past that even with a 15 pitch prop, will try without the orange wires next time out.

[hupiveneilija]

You know when limiter kicks in, it starts to cut ignition. Mine did.

[filthy phill]

There are many different types of rpm limiter, some come in and out fast like when over revving the motor cycles with ignition cutting in and out.
Some come in steady and just keep the rpm at that level and dont drop in and out.
I think I have the second type, its like a soft limit if you know what I mean,
the thing that makes me think like this is because I am getting same rpm limit with a 17,19,21, and 23 pitch..
always at the 6000 to 6100 rpm mark.

Would be absolutely fantastic if I can get around 6800 to7000 from my Oval port 56 with a 13x19 or 21 pitch...

the rev limiter is 6700 on a 1995 oval port

[hupiveneilija]

the rev limiter is 6700 on a 1995 oval port

You were quicker:p. Just checked that from manual also.

[filthy phill]

Yeah I hear what your saying little charger.
But I am not the only one to have noticed this . Lots.of the rnli motors will only rev to 6000 rpm too. Some of the tillers would not go past 6 grand neither so that really means the ignition limited to 6 grand. Lots of people also say the number is on the box ? Well no it is not, I have 3 of these all good and none have any numbers relating to 6700. I looked at new pack at a dealer and again nothing to corrosion with 6700.
Maybe that is just for USA and Canada market ?.
Mine definitely won't go that high.

[hupiveneilija]

Not even without load? Start raising rpms higher, but not too quick, in neutral and see if it stops to 6100. Or do testprop with really short blades so it gets just a little power to turn it.

[filthy phill]

OK here is what happens if you rev it up without prop or tiny test.prop in tank.open throttle gently to 5,000 no problem. Keep going and it will slowly stop picking up at 5900 to 6000 and not go any higher than 6100.
If rev it up.fast it shoots to over 7000 then drops back to around 6300 quickly then a couple of seconds it sits at 6100.. does same with 3 different packs.

[hupiveneilija]

Well then you have to unconnect orange wires and go water with smallest prop you can find.
You must actually DO something to find out rather than discuss here!

I have 1997 60hp ovalport on a aluminum fishing boat wich has bottom like wawe sheetmetal, looks like roof of the house, it goes 36-37kn with 18raker rpms were low 6k dont remember.
Then i had another aluminum boat, 4m long shallow-v, it went 41kn same 18raker with my 1992 bp wich was totally stock 60hp back then. Revs were 6900 stock everything.
So there you have one comparison.

Why not buy the performance pack from CDI electronics part No. 213-2138. These are limited to 8,000 RPM. Available through E-Bay.

[filthy phill]

I know about the orange wires, it was me who posted about disconnecting them. Cdi do not sell any power packs for the oval port that are above 6700 rpm. .they stopped doing them.
Disconnecting the 2 orange wires gets rid of limiter and quick start. But simple to just put in a switch to use the facility then switch off once warmed up and ignition in normal running state.

Steves Jem
the CDI electronics part No. 213-2138 is for the older type electronics on the bridgeport motor.thicker flywheel and different rectifier than oval port ;

just taking the two orange wires off is very simple and then if it works and is completely unlimited that has to be the best way to go.
it will still leave the S.L.O.W function and can use quickstart by simply putting a switch in the orange wires.
