Default 1850ls / Rev4 19 pitch too big?

I know this has been a well debated topic,but is the Rev 4 19 too much prop for a Yamaha F150. The stock 21 pitch 3 blade ran 49 mph at 5700 rpm ,but terrible hole shot. The Rev 4 offers a better hole shot ,but lugs at the dock and low speeds making handling difficult and it seems when 4 people are in the boat it just can't get out of the hole. The 19 turns 5600 rpm. I know it will be easy to sell the Rev 4. Should I buy a Rev 4 17 pitch?

Clearly the 19 pitch 4 blade is too much prop for you rig.

Be safe

I have the same boat and run a rev 4 19 P with a 175 Verado and it works great. I would think this prop would be quite a mouth full for a 150, especially with any load in the boat.

Agree 19p will be to much. You need a 17p if going rev 4. I just went threw the propping process this past month on my 2013 yammy f150 on a 2003 pro v. I tried a rev 4 17p. Got rpm up but was slower than others. I tried a dozen props and settled on a Yamaha reliance 19 13 3/4. Reliance props are designed for the yammy inline 4s I'm pretty sure. Fastest and best all around prop I tried. Mercury enertia 18 was also a good prop.

The prop you want to run will depend on what you want out of it for performance. If you're looking for all out speed, the Rev 4 will likely not be the wheel of choice. Once you have the right pitch, it will however offer a good hole shot, excellent handling, and good bow and stern lift. If speed is your huckleberry, then a Tempest, Raker, Enertia, or similar will likely be what your after. FYI, I have a 200 Opti hanging on a jack plate on a Bass Cat Calico (AKA Yarcraft 186FSX) and run a DAH modified 19P Rev 4. with a normal or light load, I can overturn the rev 4 rpm wise but I would I expect it to be to much wheel for a F150 Yamaha on a Ranger 1850. I also have a 21P DAH Tempest Plus for those days I crave a little more speed.

Ive got a 2005 1850 with a Yamaha F150 and 17P- Rev4, and am very happy with it. With my wife and I it runs 42mph @ 6000, very good holes shot, around 18mph plane speed, and good control. When I make long runs we usually only cruise around 30mph so top speed is not a concern. I had 5 250 plus pound men in this boat with full live wells, coolers, and fishing gear, and it took some time to come up on plane but she got us there! I was very impressed because the boat was clearly overloaded. Pulled tubes and skiers vey well.

I just picked up 17p Rev 4 for mine. 2016 1850ls with a yamaha 175. I had a 18p power tech before that. The 175 has a 1.86 gear case not the 2.0 gears. Used it once on rainy lake last week. 3 guys, 3 big tackle boxes, full live wells, full gas tank, full beer cooler, anchor, and compartments full of stuff. The boat spun it around 5700 and 46 mph. That was trimmed way up on some chop. Seemed to be about 200 more rpm and 1-2mph slower than the 18p power tech. My vent plugs are still in the Rev 4. It got to 45 mph pretty easily.

Call Ricky at brainerd props. Tell him what you have. He is fair and knowledgeable. He also set me up with a Solas hub that has less prop chatter than a flow torq 2.

I'm going to do a little more testing with it this weekend. I my pull out the vent plugs and see how much it changes things.

I have a powertech 14.25" diameter, 18p 4 blade on an 1860 with a yamaha F150.

Hole shot is amazing, WOT = 5800rpm, 44mph.

I think i'm giving up some top end speed but happy with the hole shot, grip and overall performance.

Question

I also run a 150 Yamaha on a 2014 1850LS. The 19 pitch Yamaha prop was not the answer. Right now I have a 17p Merc Vengence. The hole shot is great even when fully loaded however I top out at 5700 rpm which is 41 mph.
I will be trying the 17p Yamaha this next weekend.

With what I have now I can cruise at 33 mph which is 4600 rpm. I probably hold it there for about 10 miles at a time. Is that running it too hard???
