prop for tabs 5m with 115 etec

[lamontsa]

Hi Folks,
I've just bought a 2nd hand tabs 5.0m territory pro side con with an '07 115 etec (50hrs).

Went for a run at the wkend, and WOT top speed, GPS, was 30.3 knots with 2 blokes & full tank of fuel..... Have had a look at a few other threads here and elsewhere (http://www.sportsfish.com.au/forum/t...TOPIC_ID=25518), and seems i could be getting a little top speed?
(used to own a 14ft with a 25 yam, so don't know too much about prop selection etc)

Any suggestions or advice would be greatly appreciated!

I got a 19 pitch S/S 4 blade on a 90 HP optimax (has same power as 115 etec) on 5m makocraft side console (very similar weight/setup to 5m territiory pro) It goes about 45MPH at 5600RPM ....told by most blokes and mechanic that its set up right. Feels all right! sounds all right, goes all right...spose it is!!

somewhere around a 19P should do the trick..them TABS are a great looking setup. You will love it I reckon.

cheers steve

Speed does sound pretty low, Mine with an Original SSP 13 3/8 x 17 , pulls 43kns at around 5400 with wife, kids and fuel

[flybloke]

That is Low
Ive got a 5m heavier plate boat then a TABS with a 70hp 2c Tohatsu that does 38 knts and gets there Quik.
But my boat is only 2m beam, Im sure Tabs 5m boats are much wider then 2m and that slows them down.
A 115 E-teck should be kicking the arse of any 5m boat. Maybe the original owner had it proped for hole shot and load, Rather than top speed??

[lamontsa]

Yeah, that was my original thought, that it was a little slow at the top end.
It was only a test-run, so was too busy checkin everythin else out to get revs at wot.
it sounded like it was wasn't straining at all at wot tho, and could pull the throttle way back at top speed without revs dropping.
the fella i got it off reconed he's only be out in it once in 8 months (thus sellin it), so don't think he had much of a chance to get a feel for it, but he did recon it'd go no dramas with 4/5 fellas and all the gear (a coupla too many fellas in my opinion tho!)
i did think that the 115 would be ample for the boat tho, hence my Q about the props...... sounds like i could be lookin at about 70kms if propped right?

Can i go to an evinrude dealer and borrow test props? or how can i prop the boat without spending $$$ on the wrong or 5 diff props?!

Thanks fellas!

Mate, I have a 115 2 stroke yamaha and it does 34knots at wot.
Boat is Tabs 5.45 Ocean series, with 3 POB + 150 litres fuel.

lamosta, you boat is basically just smaller than mine and has less drag so it should acheive at least 40knots.

Mate, need to know what are revs at WOT. I recon it should be pulling at least 5500. It sounds like its over proped, supposedly for economy, but in fact it works harder, using more. I had a 5.2 Sportfish (plate) with 90 and it did 35kt. Cheers Pete

Optimum WOT revs for a 2007 115hp is 5,600 to 5,700 rpms;

I know this might sound a little stupid buy has you prop got any nics in it ?


I cleaned up my prop and ploshied it up real nice and the old gilr picks up a few more knots

the britsh navy spend alot of time makeng sure their props are in exelent nick

I have the same boat with a 115 merc 4 stroke with a 4blade trophy prop and my boat is good for 48.

lamontsa,
really need to know what make and style of prop ( BRP? Stainless or alloy?), what dia and pitch as well as rpm's, otherwise we are all trying to take a guess. You stated it carries a large load easily and you can back off on the throttle and not notice any rev change i would say you are under gunned and need a bigger prop. Get all the info and let us know.

Thanks for the feedback fellas. Hopefully give it a run this wkend, and will take note of the WOT Revs this time!

[lamontsa]

Okey dokey fellas. went out yesterday, 2 blokes, full tank fuel. WOT revs are at 5300, again just over 30knots, flat water.
Approx masses are boat - 500kg (5.1 side console from website is 540kg), motor - 170kg, fuel - 100kg (120l), 2 blokes - 200kg, misc stuff 100kg?. totaling 1070kg?

The prop is an SSP 13 7/8 17p. does have a coupla small nicks. pretty good nick tho (has only done 50hrs).

I did notice the boat needed constant steering correction whilst not on the plane - not sure if the bimini was acting as a sail or not? once on the plane, all good.

The motor is mounted thru the top hole of the engine mount. Have read somewhere here about that issue too. The engine model is E115DSLSUC....

Thanks fellas!
