I'm thinking of putting a Stilleto Bay1 14" on my 1988 18 Outrage with an F115.
Reason is to carry a heavier load. By this I am being optimistic with fish.

Previous Ballistic 17" got nicked and I want a prop to use while it's being repaired.

The Ballistic was good for 5900RPM lightly loaded full of fuel.
Weighed down with trim more suited to choppy water yielded 5500-5600.

From reading threads, I believe the cupping on Stiletto's make the prop act like a prop 2" more (Stiletto 15" like my Ballistic 17").
A 4 blade brings down the pitch again. So...

Anyone try this combo?
What do you think?

Send an email to Tom Clark. He sells them and of course can tell you about the probable outcome.

I don't have the same setup, but similar, which may provide a bit of insight:

1985 Outrage 18, 2014 DF140A Suzuki w/2.59 gear ratio. We currently have an 18p 14" Stiletto Advantage 1 on it...the boat will just do 41mph as the engine hits the rev limiter, with two people aboard, at 1100' elevation, with a half tank of fuel.

The hole shot is at least as good, if not BETTER than our old Johnson 150 V6 with a 19p SST.

What I notice about the Stiletto, is that it lets the 4-stroke find it's revs easily, and it needs to use its revs to accelerate, unlike a 2-stroke which uses it's low rev torque. When I punch the throttle, the engine very smoothly and progressively spins up as the boat pops out of the water and takes off. It's much better out of the hole than I expected.

When we go fishing, we run pretty heavy with fuel load and gear. The boat still gets up and goes when loaded.

I need to go to a 20p, but am very impressed with the 18p Stiletto so far.

Thanks for the info.
I bought a Stiletto for my Merc 50 on a 15 Whaler and absolutely love that prop!
I'm sold on Stiletto. I'm just wondering on how the performance of the 4-blade Stiletto compares.

I don't have your combo but FYI regarding your comment about the design of the blades on the Stilleto 4 blade propellor, here's my experience:

200 Dauntless with 175 HP Verado:

WOT RPM with OEM Mirage Plus 17 inch pitch prop-------------6300 (OK)
WOT RPM with Stilleto Bay Pro lll 4.47 series 17 inch pitch prop--5600 (not OK)

that was a much bigger drop than anticipated from a change from 3 to 4 blades of the same designated pitch.

with the 17 inch Stilleto 4 blade the engine was obviously laboring with a heavy load of people, seemed OK when I was alone

My solution was to drop to a 15 inch pitch Stilleto prop of the same model. this feels like driving a car around in one gear too low at times but with a load it is perfect and allows staying on plane at a speed 3-4 knots lower that with the Mirage Plus 3 blade, handy in a big chop.

Tom Clark was extremely helpful in selecting a propeller for my 1988 15 Whaler.
I know it is not the same animal as your 18 Outrageā€¦ but Tom understands much more than pitch and diameter as it applies to the individual hull, propeller, and the type of horsepower on the transom.

I had a similar situation as mentioned above . . . I re-powered from a Yamaha 70 2 Stroke to a Yamaha F70 4-stroke. My propeller selection when I purchased the motor was WAY off. Tom got me dialed on his first recommendation.

I then had an extra prop that I was un-able to use, my local Yamaha dealer traded me straight out for a new Turbo FX4 which I have only ran twice. The difference in the handling characteristics was amazing.

If you have the opportunity to communicate with Tom, (and others) to develop a consensus, it will save you a ton of time and money.

I haven't got the final jackplate height dialed in just yet. But I now have 2- quality propellers to work with. Once I have the time to test both and maximize the jackplate height for each, I will post my findings.

Lots of valuable info here.

Thank you for the reply. I will contact Tom directly.

Come help me pick my stiletto prop for my 15 whaler with a 50 work and it was pretty much dead on.
I thought I would just go to the question how to do community is there someone that Pride particular combination I am interested or have some more real-time experience with the Stiletto 4 blade.
