when does the rev limiter kick in 1995 60hp evinrude triple

[phillnjack]

I have tried a few places and not got any definite answers to my question.
I have 1995 evinrude 60hp triple.
the cdi unit/powerpack is numbered 585145 made in mexico.
I cant find any other numbers or details apart from what is on the little white sticker.
and on the back a large number 3 ?

so I have no idea what the rev limiter is on this engine.
I obviously would like to know then I can see if I am getting its max performance from my props & set up etc.

I need to know if it jumps in at 6000 or 6300 or 6700 etc.

any idea's on this would be nice

6700 rpm !!!!!!!!!
wow that's pretty high, are all these limiters with this number that high ?
I know that cdi do one at that rom but didn't know the originals could get that amount of revs.

this makes me need a smaller diameter prop than I was thinking, similar pitch but definitely smaller diameter.

thanks for the info.

Full throttle operating range 5000-6000rpm

[phillnjack]

so if full throttle is 6000 rpm why would the limiter be at 6700 ?
and what would be the downside of taking it closer to the limiter ? or is it a case of the power curve is only within this range.

Full throttle can be anywhere between 5000 and 6000 anywhere over or under can damage powerhead ( in theory)and will cause loss of HP. Not sure on your motor but usually when full throttle is between 5000 and 6000rpm peak Hp is 5850rpm. I think you will find if you prop it to 6000rpm it will be slower than if you prop it at 5500rpm. Rev limiter is for if you spin a hub or jump a wave and the rpm's go way up above 6700rpm,not so you can run it a 6600rpm. Get and read your manual.

What you need to do is pull it down, port it so it will pull to 6600rpm give it some more compression then you can utilize the 6700 rev limiter.

its on 150 psi now and I run just pump gas.
this has the idle relief holes in the bores, if they were shut it would be 160 psi, so compression is way up their.
Don't want to close them off as I do like the smooth idle and slow running now and then.
So I will take your advice and prop it for about 5800 to keep the powerband happy.

thanks for the help and advice, and all nice and clearly put.
