UPDATE (2016-02-20):

As many of you have said, and my dealer also says, the Yamaha SWS II 15.75" x 15 is out of stock.  I'm told at the end of March or so, they should be in.  That being said, my dealer switched out the last prop for a 14.25" x 15 pitch prop.  This prop was better than the 15.25" x 12  pitch prop, but only a little bit.  This one topped out at 35MPH (GPS and speedo) with 7 people aboard.  The RPMs were just a hair over 6,000.

I will keep this prop until the SWS prop comes in next month (hopefully).  I'll post another update then!

This was day of delivery. 50 gal of fuel, anchors, misc. gear, 2 adults, WOT. 


Anyone have opinion on spare prop?  I would like to get one for safe measure.  The current prop has a great hole shot and over all top end speed. 
 
Why don't you try a 16p Enertia? It'll get your rpms up unless it changed since new.

UPDATE (2016-06-19)


While I was driving up to our lake home on Friday evening, I received an email from my dealer saying my props were in!  I had two props I wanted to try.  The first was the 15.75" x 15 pitch SWS II SDS prop, and the second was the 15.5" x 17 pitch SWS II SDS prop.

  • Boat Model --------- 2550 QCB
  • Model Year --------- 2014 
  • Tube Option -------- ESP
  • Power Option ----- Yamaha VF250 SHO
  • Prop Specs ---------- 3 Blade Yamaha SWS II SDS 15.75" x 15 pitch
  • Performance ------ 40mph @ 5600rpm on GPS

and the other prop

  • Prop Specs ---------- 3 Blade Yamaha SWS II SDS 15.5" x 17 pitch
  • Performance ------ 40mph @ 5200rpm on GPS

and the one I had been using for the past 3 months

  • Prop Specs ---------- 3 Blade PowerTech SS 14.25" x 15 pitch
  • Performance ------ 40mph @ 6000rpm on GPS



So, of course, the question is, what the hell?  My boat is a big boat (27' LOA) and heavy.  It seems that 40 MPH is about the top end for me, but I am getting about 40 MPH at three very different points.  The Yamaha 17 pitch prop won't go past 5200 RPMs, the Yamaha 15 pitch won't go past 5600 RPMs, and the PowerTech got me the full 6000 RPMs...but with the same top speed.


All of these tests were done with a full (or near full) tank of gas and 2-3 people on board.  One thing I did notice, is that with the Yamaha 15 pitch prop with about 10 people on board, I was still able to hit about 36 MPH.  With the PowerTech 15 pitch prop, a boat load of people kept me in the low 30s.  I haven't tested the Yamaha 17 pitch prop with a boat load of people yet.


I would think I would want the engine to rev higher than 5200 RPMs.  I guess it's more fuel efficient, but I don't know if that is good or not.  Anyway, any experience, expertise, or guidance would be great.  I'm also talking to my dealer.


Thanks!
 
JRM55's Boat

  • Boat Model --------- 2550 QCL
  • Model Year --------- 2017
  • Tube Option -------- Tri Toon-ESP Package w/Lifting Strakes all 3 Tubes
  • Power Option ----- Yamaha 300 XCA
  • Prop Specs -------- 3 Blade Stainless steel Lexor 15.75 X 15
  • Performance ------ 44mph @ 5900rpm on GPS - Early Morning, smooth water, one person, 3/4 tank fuel (approx 40 gal)

I was hoping for better top end speed and am open to any suggestions.  Engine is mounted in #1 hole.  Was running a  15.5 X 17 prop and got 46 MPH @5200 so changed to the 15 pitch and improved RPM but lowered MPH.  I was wondering if this is the best it's going to get on MPH.  Boat weighs with motor, no gas about 3900lbs.  Boat runs great like this but hoping for more top end

I would guess Lakeside is your dealer?
 
I am....... :wacko:
 
I stopped by there earlier in the summer as I was passing by. So many boats not on trailers, no rigging or covers. Didn't seem like a very professional approach.
 
Is there a bleeding from ones mouth emoticon?

I have been dealing with them for a couple of years with no issues. Not sure why boats need to be on trailers? I would say that 90% of people in the area do not buy trailers for their pontoons. You are correct on the covers being off for many boats.
