140hp Suzuki Prop Pitch for Alum Nav

Recommended Posts

I'm just wondering what pitch of prop will give the best performance on a 2007 Suzuki 140hp 4-stroke for a 2007 17ft Alumacraft Navigator. THX!

Can you provide a little more info?

What you're running for RPM at WOT?

I'd say a 21 or a 23 on a suzuki due to the gear ratio they run... but that's a guess without much info.

I'm not sure what WOT is, but I'm not sure of the current pitch either. I'm just wondering if someone has this motor on a similar rig that can recommend a pitch for good performance. Right now its running in the low 40 mph range.

WOT + wide open throttle.

The boat you have plays a huge part in this as well.

Find out your RPM at WOT and that will help a lot.

I have a 115 yamaha 4 stroke on a 17' Explorer and can get 45 mph with a light load. Im guessing you should be in the mid 40's reguarly and hit high 40's every once in a while.

Im also guessing but I would think a 21 would do the job.

Call Jay Soderbloom and ask him. He really knows his props. He can also get you a prop at a good price. He is also a sponsor of FM. www.soderbloom.com

I had a 21 pitch stainless steel prop on my former boat. It was a 140 Johnson 4 stroke (same as Suzuki) on an Alumacraft Dominator 175 CS which is also almost the same boat you have. That ran me within the recommended RPM range near the top. Although, I cannot remember what exactly the RPM range is?? It is in your owners manual.

I have the same motor on my Stratos 386XF. It should run max RPM's at 5600-6200. On my boat after trying a few different props I found the best all around prop was a Suzuki 14 x 20 SS prop. It runs at 6000 with a light load and 5700-5800 fully loaded. I also was very close with a Turning Point 13.25 X 19 SS prop that would give me a better hole shot but would not let me fully trim up for max speed and RPM's. I still have this prop if you would like to try it on your boat, it might be a good match as your boat is a little lighter than mine. I also have a spare 14 x 20 Suzuki prop you could try.

21 pitch should do you just fine. That is what I run on mine. It started off as a 23 on the boat but it was really slow to plane out with a load. Now with the 21 it jumps out of the water. I do have to be careful not to max my RPMs when i am planing up somethiing to be careful of. This is on 1775 prov which is similar to your set up.

    • Among other wilds that have moved into our urban areas, we can now add loons.  There is a breeding pair on the lake formerly known as Calhoun, mostly staying on the west and northwest sides.  But there is also a bunch of yearlings fishing the east side, numbering maybe six or seven and so unafraid that they come right up to the 36th Street dock and try to steal suckers being used for musky bait.  Maybe the call of the wild is not really so alien to the South side of Minneapolis, but it looks like the loons have moved in and can be heard calling from time to time. 
    • Sounds like you guys gave her heck up there to find them. I'd be praying thanks, too if I got that one on! ☺️
    • Quick recap:   Weather was too darn “nice”!  Upper 80’s - 90’s; no wind to speak of; mostly sunny. Water temps were anywhere from 64 - 71 depending on location and day.   We looked the lake over from end to end, marking up our map and returning to some places where we saw fish either later the same day or a couple days later.  We could literally see the transition from spawn to post spawn happening during our stay.  Being new to both muskie fishing and that lake, we spent time in dead water as much as good water but feel like we got a pretty good handle on how to go about setting up a more efficient return visit.  It was a lot work and long hours but I’d go back this weekend if I could so I must’ve enjoyed it.   A few pics as hoped for:
    • big dave 2 and leech, darn good lookin meals!!!!  Dave have a good weekend!!!!
    • Ok Dave have a good weekend. Hope you get over the whole butt hurt Leech deal! Not sure where you got that I don't like folks smoking or grilling things?  I know I do enough. Have fun! 🙂  
    • Heavy rains across northwestern Wisconsin last weekend and early this week have flooded some roads and caused washouts on some highways, roads, state parks, forests and trails. According to the National Weather Service the area has received 7 to 12 inches of rain from Friday through Monday.Several park system property or portions of properties are closed due flooding. Amnicon Falls State Park, closed temporarily but has reopened, though some roads, trails and observation areas remain closed. Pattison State Park is open for camping only; all trails, observation areas, picnic and day-use areas are closed. There are washouts on the dam that forms Interfalls Lake and Highway 35 over the dam is closed. A campground and horse trail are closed at Governor Knowles State Forest and the day use areas along the river at Interstate Park are underwater.Water was roaring over Little Manitou Falls at Pattison State Park.Photo credit: Gervase ThompsonAll rivers in the region are running extremely high. The falls at both Amnicon and Pattison are roaring, but road closures mean observing the falls now is challenging. The Bois Brule and Flambeau rivers are high enough that some canoe launches and campsites are underwater. The water is making its way downstream and the Lower Wisconsin River is running very high with all sandbars submerged and canoeing and kayaking not recommended. The river is expected to crest Muscoda this weekend at 40,000 cubic feet per second. .
    • I'm still going to smoke this fatty while camping this weekend whether Leech likes it or not.....😋       See you fellers on Monday........
    • Rick didn't like all the "My Grills bigger and better then yours" posts!  😅
    • We switched to a new server. Had a glitch in our dB that lost a couple days of posts.
    • I ripped a hole in one of my favorite pairs of fishing shorts just need a decent sized patch to cover her up
