Great looking boats everyone!
How do you like the Yamaha F150TXR????? Enough power, or do you wish you had the 200 HP like NelsonQ?
The 150 is a nice engine, but I do wish for more power occasionally with my 2100. I wanted the F200, but we got such a good deal on the F150 plus the extended warranty, and the dealer threw in some extras that I just couldn't pass it up. Top speed is around 40 mph so far with a full load (gas and water tank full, tube, stuff, plus 2 adults and 2 kids). Hole shot is good, but I haven't tried pulling a skier yet, but I have pulled a 2 person tube with 2 teens with no problem at all. I only have 17 hours on the engine so far, so its just getting broken in. Once I get it fully broken in, I may consider a prop change, since so far I'm only getting to about 4800 rpm at WOT.
Just another piece of info..... 150HP was my target engine and I think is plenty for the boat. I decided on 175HP as an insurance measure with no weight difference. Long story short, there was a mixup/problem with my motor, and I got the 200HP upgrade at no cost(Great dealer by the way and I covered it in my review of my boat)
Ernest, consider a 4 blade prop. I have a 5 blade SS prop on mine.... If I hit it hard with 3 people in the boat and two people in the tubes, I can literally pull the tubes from under them there is that much greater hole shot and greater 'traction' in the turns.
Check with your dealer if they have a try before you buy prop option and give a 4 blade a consideration. It'll drop you 1-2MPHs at WOT for the same pitch but at 4800 RPMs at WOT you'll most likely change the pitch. What are you running now for a prop (pitch, SS or aluminum) and what is the WOT range on the F150?
Currently my F150TXR has Yamaha the Reliance stainless 14.25 x 17"P 3 blade, and I'm getting about 5600-5800 RPM @ WOT depending on my load. According to shop and owners manual, between 5800-6000 is peak on the F150's power band range. I've not heard about gaining RPM that much upon new engine break-in? But then again, there's ten billion things I know nothing about. :redface: If you want more speed try a 19" P 3 blade. You should be turning ~ 55-5600 and still be in the power band WOT range of @ 5000-6000 RPM.... My 19" P 3 blade got me 45.9 mph @ 5500 RPM, but I lost some hole-shot. I would gander a 4 or 5 blade would be killer hole-shot but even with correct pitch I'd guess ~ 35-38 MPH would be tops... See we F150 folk do need the damn F200TXR's!BTW, I installed digital Command Link tach from Yamaha ( cool stuff google it! ) and my analog tach was off ~ 600 RPM!!!!! crazy! All in all the F150 is a great engine, but the F200 would be a tad more fun, maybe even crazy fun.... Lucky NelsonQ!!!!!!
BWT: the 4800 RPM you talked about, sounds like your running a 21" or 23" P prop. Or maybe your analog tach is off like mine was.
