last Oct i blew one of my pistons (as in a hole in it) on my port 200, 2001, Yamaha. Since i had another 200 Yamaha to not only cruise, but to be able to get on plane, i've used it, with no loss time on the water. However, as stated in one of my "Christmas posts" i asked for new motors. Low and behold, sure enough, i apparently was a very good boy this year, and got a new set of the new 2013 Mercury 4 Strokes, 150 hp. That said, they are on back order, and due to arrive mid Feb. My 25 Whaler, with Whaler drive is already at Victoria Marine in Tx, to have the Yamaha's removed, and hopefully sold, along with all the rigging, binicale etc. So, following what i considered, sound advice, i have not selected a set of props and am ready to toss this post out and start dialing into a set of props so i have them when the boat is rigged and ready to go.
I'm also going with the Smart Craft Gauges, and the HDS-8 Lorance GPS fishfinder. Should be SWEET when its ready to be picked up!
I will be traveling a lot in the coming weeks, until mid March, so if you post something and i don't respond, its because i'm not home. But, on my return, one of the first things i will do is check recommendations!

Great duf.
Did you get the regular Mercury 150 4 stroke or the Verado?

Duf ordered a pair of the new FourStroke 150s, not the Verado 150s.
With its 1.92:1 gear ratio and a 5800 RPM redline the 15-1/2" x 17" Mercury MIRAGEplus would be my first choice but the 14-1/2" x 17" Enertia would be worth trying as well.
Mercury does not make the 18" Enertia in counter rotation, so it's not an option.

Tom is correct Joe, i got a set of the new Mercury FourStroke 150. Looking forward to getting them dialed in, and testing the new combo on the water.
Tom, my next trip is supposed to be next Sunday, to Ft Lewis near Tacoma. If your nearby, perhaps we can chat!

Mercury is showing the gear ratio on the new 150HP FourStroke EFI at 1.92
http://www.mercurymarine.com/engines/...0/?model=0
I'm thinking maybe 19" Enertia, if the engines are as powerful as indicated. The boat should run close to 50 MPH for 19's to be the choice, and if the Enertias prove to be the 2 MPH faster than Mirage Plus. If not, then 17 Enertias will probably be the choice.
I think on a Whaler Drive 25 the engines have to be mounted up all the way, in the 5th set of holes.

Yes, the gear ratio is 1.92:1 which means 17" pitch props.
A Whaler Drive equipped 25 with 300 HP should be good for 44-45 MPH. No way in hell it will be able to turn 19" pitch props.

My 25 ran right at 50 with the 2 200 2 strokes, so i'm not to condident it will run at 50 with the 2, 150's. No matter, if i get 45 plus will be happy with the improved milage. My 200 also had 19 inch props.

If the boat ran 50 MPH with 200s, ceteris paribus, it will run 43.3 with 150s.

And again, i'm ok with that. My normal speed running is about 35/40 when i kick it in the butt, and offshore, if i'm doing 30, i'm estatic. With the normal 3 to 5 swells, you are doing well to exceed the 20 MPH mark. "Thats all other things being equal or held constant."

Here's the latest update. Motors are arrving tomorrow, and my plan is to hang the same props 19 pitch that i had on the 200's , on the 150 Mercs and see what they do. Tom is suggesting it will be to much pitch, and i don't disagree, but it will be a good starting point. I have a place here locally that can re-pitch my props, and if I dial it into 17's like he suggests, once dialed in, will look at obtaining a new set of props.

Duf -- It will be good to get that data point. It will make it easier to figure out what you really need.
But do not rework your existing props if you are going to replace them. That will make it much harder to sell them; nobody wants to buy used AND modified props. Try them out, get the data and then sell them.

Congratulations on the repower Duf, although I was kinda hoping you would go with the Yamaha F150s because I have been looking for a 25' Outrage WD for an upgrade myself. Based on the performance of the F150 on my 22' Outrage, I thought twins on a 25' would be a sweet match. However, technology as it is now days. the Mercs ought to do real well. Looking forward to hearing about your performance results once every thing is rigged and dialed in. Good luck!

Much thanks, and you might want to touch base with Texas Whaler who has fairly new twin 150 Yams on his 25 Whaler (pictures on Whaler Central) for some insight. John seems real pleased with them so far, but am sure he could give you some additional information. He does not however, have a Whaler Drive.
Tom, received and copy. Not sure i can find a set of 17 pitch props to play with, but noted your selling point.

Duf, you probably know this, but if it turns out you are indeed very operpropped, so you can't get up into the recommended WOT range, drop back immediately and dawdle back to the dock.

Duf - I also would recommend against altering the Yamaha props, unless you plan to keep them for spares. It will kill resale value.
I think you are going to end up with a pair of 17" Mercury Enertias, which could give as much as 48 MPH top end. I have heard those engines will be putting out more than 160HP each.
17 is definitely looking like your pitch range. It's just a matter of which design you want to spend you money on!

There is a very real possibility that you will not be able to follow the break–in procedure properly with 19 pitch props....

I forget exactly what model of propellers Duf had on his Yamaha 200 HPDIs but regardless, 19" pitch props on his new Mercury FourStroke 150s will probably not be optimal but they will be fine for testing.
The recommended WOT operating range of the Mercury FourStroke 150 is 5000-5800 RPM. The 19" pitch props will put those motors well within that range. Depending on the model of propeller ultimately chosen, 18"or 17" will probably be better in the long run, but what Duf has now is going to work for the time being and also be a very helpful data point.

Ok, just back from another trip (God i'm looking forward to retirement) and am catching up. All good info, sounds like a. Tom's good with the 19's for testing, but i should note if i'm not up a minimum of 5000 RPM's for break in, that may be an issue, will have to read the break in instructions. and b. numerous of you have recommending not changing the pitch on the 19's to 17, or 18 for value loss. Just so happens, just read a PM that another Whaler Central member forwarded to me with someone with a set of 17's, are looking for 19's.
Latest is, i should pick my boat up no later than next Sat, maybe sooner, so should have the initial post of speed/RPM's in accordance with break in, available shortly.
Tom, if there is any additional info you need to help me dial in the props, let me know, other then approximate weight, passengers, fuel, conditions, etc.

Well, finally got my boat back. Rule of thumb, figure out a schedule, and add a month or so. Here's a link to some photo's of the new motors.
Going to take a week to compound and wax the hull, then some other odds and ends, but would like to mention Victoria Marine, for doing a jam up job on the installation, and Jaco's Marine for a great deal on my motors!
