Member Posts: 242 Comments: 0 Joined: 07/24/12	I just installed a 130 HP E-Tec on my 1984 Outrage 18, I had to make a desison on the prop with the purchase, so I got the 14-3/4" x 17" Viper. Any ideas on what to expect or suggestions on a different prop? I have not had it out yet as I still have a bit of work to do. Any comments would be appricated.

If you installed a new Evinrude E-TEC on a 1984 Outrage 18, then I'd say that is a great prop to use, though maybe slightly under-propped. Try it out and let us know how it does. Top speed should be 42 MPH if the motor was mounted three holes up as it should have be.

It also uses a low 2.25:1 gear ratio. I suspect you will end with the 14-1/4" x 18" Viper instead, but test what you have and see how it does. Check that motor mounting height.

I think I'll not go for top end until I get 5-10 hours on it. I know about run it right out of the box but I'm gonna pay it slow.

Not for very long mind you but a minute or so was fine. With the new E-TECs, which are run in at the factory before being crated, you do not even need to do that. If you want a fast motor, run it hard. Waiting 5-10 hours is ridiculous. Read your Owners Manual and follow the advice offered.

Member Posts: 242 Comments: 0 Joined: 07/24/12	Took the boat out to test run the new motor and prop. (1984 Outrage, 2013 130 hp E-tec 4 cyl. with the 14 3/4" X 17 Viper) had it up to 38 mph (gps) at 5700 rpm had two people on board and 30 gal. of fuel. I still had some throttle left but not much. Is this about right or should I go to a 19 pitch. Thanks for your help.

You are already beyond that with more throttle left? You need more pitch. As I said earlier, I suspect you will end with the 14-1/4" x 18" Viper. 19" will be too much.

Tom, can you please provide a link to the 2013 RPM ranges? I could only find the listing for 2011 engines thanks

Member Posts: 242 Comments: 0 Joined: 07/24/12	Well, we took the boat out today for test running of the new prop, (1984 Outrage 130 hp, 4cyl, 14 3/4 x18 prop, 60 gal. fuel on board, two people, running into the wind,small chop.) Results-5700 WOT 40MPH. I am thrilled!! A little less fuel on board and I'm sure it will hit the expected 42 MPH. It handled great, just a little adjustment on the trim tab is all. Thank you Tom for your knowledge of props and sharing. So I declare the completion the restoration, the trailer is next. GO Whalers. We got a ton of "WOW what a beautiful boat!" Even from a lady whoe's husband was launching a brand new boat for the first time. Edited by aeriksen on 05/11/13 - 9:49 PM
