proper prop for Etec 60

[Bleakco]

I recently repowered my 2001 X with a 2006 Etec 60 and was curious if anyone else had done the same...The PO had it on a 18 ft fishing boat and it is proped with a 15.5 x 15...It will only get 4000 WOT on the Mac should I look at a smaller diameter or pitch change?

Call Mike or Jeff Inmon at the factory - - - be sure to tell them at what altitude you are boating. You should be getting more RPM's.

I agree with Rick. I have an Etec 60 on my and hit aound 5200+ RPM at WOT. ( the lakes in my cruising 'grounds' are generally around 700' elevation)

Sea level--14" dia. x 13 pitch, 3 blade std OEM alum. should get you 5,500 rpm with full ballast. Optimum on that engine is 5.650.

Thanks all
The Mac weighs 4 times what the seaswirl weighed so I figured the prop was wrong for me....

iNSTALLED NEW 13.75 x 13 wot 18 mph @5100 rpms..boards up and empty ballast. I am a happy camper now...bob

Factory 14" aluminum prop on a 26M (Mike Inmon @ Macgregor). I actually topped at 22knots with the bilge bone dry (closed before launching). I was running offshore and actually managed to shake the anchor off the pulpit - I was hauling butt!!!!

The other difference was that I used 0 ethanol gas for the first time. It's more expensive but the engine was very smooth and purred like a kitten. I assume that's where the kick came from.

Jim,

was the 22 knts (?) with the 13 pitch, 3 blade std OEM alum, with an E-TEC 60?
What was your RPMs at that speed?
