Author Topic:   1994 Montauk, E-TEC 75; What Propeller

Sal A posted 05-12-2010 05:08 PM ET (US)
I have decided to keep my Montauk. I just sold my Yamaha 70-HP two-cycle over the weekend, and dropped my boat off today at McCarthy's Marine. I did change course from my original thinking and opted for the E-TEC 75 over the Yamaha F75 four-cycle.
Any specific recommendation for a prop? I usually don't boat in calm lakes, but rather in choppy near-shore saltwater. Top speed is not as important to me as is a comfortable cruise with 500-lbs of humanoids aboard.

Sal--Aside from the cost, is there any reason you are not opting for the 90-HP E-TEC?
What made you opt for the E-TEC over the Yamaha?
Sorry, I cannot offer you any suggestions on the prop.
Congratulations on the re-power.

The deal--slightly better on the ETEC. Yamaha F75 vs E-TEC 75 leftover. Both in stock. Both would be great on the boat. The 90-HP would be fine also. Comes down to what is there, and what it costs, and I just would rather do biz where I am doing it if I can.
The new Yamaha F70 looks light and right also, but I am afraid of new model years.
Thanks Dan

The deal works for me.
The weight of the F70 makes it a compelling choice for a Montuak repower, but I can understand the reluctance to take a chance on a new model.
I hit 40 MPH (barely) with the old engine, so the ETEC 75HP will give you plenty of power. There aren't too many days around here where the chop allows you to hit top speed anyway.
Did you talk with McCarthy's about which hole to mount the engine on? I thought I have read here about mounting up 1 or 2 holes for optimum performance.

Sal--Congratulations on the new engine repower...you will love the E-TEC. There are lots of good new engines out their, but you will be very pleasantly surprised when you run the "Motor of another color".
That 75 E-TEC will give you plenty of power for the kind of boating you do. And yes, not too many people are full spped in the waters you are in.
The dealer should continue to adjust a prop for you until you get it running the way you want it, and within the guidelines for optimum running RPM for that engine.
I think you will be happy with the quietness, the no maintenance for three years, the I-command among other things, and of course the torque on these puppies:)
Enjoy and use with the family in good health.
PS thank goodness it is not another boat! hehe

By the time you find the right prop, you will have it sold. Thank God you don't have any break-in time with E-tecs. Good luck and good ribbing :>)

Sal,
In an effort to be helpful, a search of this site has shown that a 13.24 x 15 Stiletto Advantage has proven to be a good propeller for a 17 Montauk equipped with a 90 HP ETEC.
Perhaps this would be a good starting.
Mayber Tom Clark will chime in.
As for mounting, the recommendation is for the motor to be mounted 2 or 3 holes up.
Dan

For a classic Montauk the E-TEC 90 is great. I would choose that model over the 75 HP E-TEC because they are the same physical size and weight and 90 HP is a more versatile power on this boat. It will improve resale value as well.
The E-TEC 90 is not heavy for a 90 HP outboard but the E-TEC 75 isheavy for a 75 HP outboard.
The savings of buying the 75 would have to be pretty substantial to make that an attractive choice.
All that said, there are not that many choices of propellers on this size of motor as compared to large V-6 outboards.
Yes, the 13-1/4" x 15" Stiletto Advantage has proven to be an excellent and economical choice of propeller for the E-TEC 90 on a classic Montauk.
Because the E-TEC 75 and the E-TEC 90 share the same WOT range you would probably have to drop down to a 13-1/4" x 13" Stiletto Advantage for it to work well with the 75.

Thank you for all chiming in.

If going with BRP propellers, a 15 inch pitch aluminum or stainless Viper should be about right.
Yiddil posted 05-14-2010 09:38 AM ET (US)
Sal, those Viper TBX props are pretty nice quality props,
The ones Ive put my mits on have been top quality and if your buying an engine froma dealer, thats not a bad choice
especially if your getting one withthe engine at no cost. Putting a aluminum prop on an etec is like putting lipstick on a pig:))
Sal A posted 05-15-2010 05:33 AM ET (US)
Viper it is. Grazi all.
themclos posted 05-20-2010 02:34 PM ET (US)
Sal,
Just checking in to see if your repower is complete? Are you going to make the Manhattan Rendezvous?
Dan
Sal A posted 05-20-2010 08:55 PM ET (US)
It should be done Saturday. when is the rendezvous? I am so far out of the loop.
themclos posted 05-20-2010 11:18 PM ET (US)
The rendezvous is June 26th.
The weather is supposed to be good Saturday. Hopefully you can take the boat out for a test run.
Sal A posted 05-22-2010 04:12 PM ET (US)
The Etec 75 is quiet, and she flies. It is very well suited to the Montauk. If one of your repower options is an Etec 75, have no qualms.

Sal...Good Job:)) You will only love her more as you use her...very capable and powerful engine...You can't do any wrong with that selection. What type and size prop did you get? Guages?You can always add on...thats the beauty of this ETEC...Have you run her yet? Have you dialed her in yet? Curious as to how that goes for you as I ponder my option on "Das Etec"
I am finding a lot of repowers with the ETEC, even in our own little group of whalers here...most have selected the ETEC over other manufacturers, just seems to be a lot of that with WHalers...I am sure there are other brands being used to repower..so please lets not got here...
Best of luck with her and all the fun you can have with your rig and family and friends...Pure pleasure to you man:)) Henry

Sal,
Very nice. How is the trim with the extra weight in back.
I have no doubt the E-TEC 75 provides enough power for the boat, given how well suited the Yamaha 70 was.
Congratulations. I am jealous.
Dan
Sal A posted 05-23-2010 11:56 AM ET (US)
Thanks Henry and Dan.
The trim is almost unchanged. The boat sits level in the water, and I need not even adjust the bottom paint.
The tach is a simple analog tach with a few oil alarms/etc.
The simpler the better in my book.
The prop is a 15" Viper.
