e-tec numbers

[lumberslinger178]

well I had the boat out all weekend, well sunday and monday , and Iam not sure if the prop is rite for the boat,

the rpms in the manual for my boat reads 4850-5850
and I was running 4900 rpms at 40 kts

not really sure what to expect , I am waiting for my brother to take the boat for a ride , he seem to know props and sizes etc

any input would be appreciated :D ;)

LS *took mine out too. *My dealer said I should be turning 5500 to 5800. *My numbers were 5100 and 41MPH. *What kind of knots were you tying? *Only kidding! * I love it! *Billy Mac *;D

[THEFERMANATOR]

Was that your wide open throttle RPM's?

[Mac_Attack]

Yes and tried all different trim angles.

Yes and tried all different trim angles.



Should get highest numbers trimmed to where it SCARES you!! :o ...

[Mac_Attack]

Yes as it's trimmed up the prop noise get louder. *I don't know how it does it but the E-Tec won't allow you to trim it out of the water. *It is so quiet you can carry a normal conversation at full throttle. *I'll be posting my videos later. *Billy Mac *;D

1st...sure that's kts and not mph?...

2nd...what condition you trial in?...flat, no wind, no top, light load, 1/2 fuel tank, and no big fat nappy-headed hos?

3rd...motor trimmed out til she suckin' ducks (scary:o), but of course the rev-limiter won't let you blow your new motor

4th...assumin' all above, yer on the bottom of the mfgr's rpm range and I agree, that may not be best prop for fuel economy/cruisin' ... how's she do comin' outta the hole?...4 grand's a good cruisin' rev on lotta boats...what speed there?...

Lumber what pitch prop you have?

Mac what prop you have??

[76GMC1500]

You should run to a prop shop and have them tweak the prop some to give you a little extra rpm. 4900 is pretty close to the minimum 4850 and that will of course go down when you load the boat down.

[labii]

That sounds low to me . That rig should be pushing 50mph .

Mac what prop you have??

14/19

[reelapeelin]

I'll take a W.A.G. at it...you are gonna get best numbers w/ a... let's see...it's comin' to me...YES...a 15 1/4 dia x 17 pitch ... try 'em all, but that'll be the one ;) ...

ALUMINUM or STAINLESS?

[Mac_Attack]

The lake was calm the prop isa 14.5 X 17.

Oh yes aluminum.

[THEFERMANATOR]

I personally have had bad luck with the newer JOHNNY-RUDE ALUMINUM props. I've got a 14X19 for my 140 that tops out at 5500 RPM's and 43 MPH, but my STAINLESS VIPIR that is 13.25X19 runs out to 53 and 5600RPM's. A little food for thought.

[Hammerhead]

A cupped 21" stainless steel prop will make that thing fly.

[buckleyjr]

Lumber - I actually have the same issue. I have the stainless renegade 14 1/2 X 17 (I have to double check this, might be 15 1/2) and turn just under 5000 RPM. However, I have a v21 and a 175 hp etec. No idea how many knots I'm going. I'd feel better if it turned in the low to mid 5000s.

I plan on talking with the dealer this week and will let you know what I hear.
