Shallowminded6 Posted February 26, 2020 Report Share Posted February 26, 2020 Any ideas on what prop I should be looking at for a 2000 18’ Hewes Light Tackle (this hull turned into the Redfisher) with a Suzuki 140? I am going to be getting the engine installed next week as long as everything works out with scheduling. The place I am getting it from allows swap outs for the first 20hrs free of charge. So even a list I should be trying would help. Never really had to prop a boat prior to this as they were already set up. Thanks in advance.

geeviam Posted February 27, 2020 Report Share Posted February 27, 2020 A factory Suzuki 3-blade stainless prop is a good prop, and made specifically for the 2.59:1 gear ratio on the DF140A. You could start with a 19 pitch, to go easy on the motor for the first couple hours of break-in, and see how it runs. But, you will more likely end up with a 21 pitch. If you want expert advice on additional performance prop options, you could give Marcus at Powertech a call. He is a.k.a. Funky Monkey on this forum.

Shallowminded6 Posted February 27, 2020 Author Report Share Posted February 27, 2020 They include a stainless 3 blade in the price of the motor, not sure of what pitch it is yet. 21 pitch would require more RPM or is it just harder to turn?

Correction - The Suzuki prop for your rig comes in 14 x 20 pitch and 14 x 22 pitch. You ultimately want your DF140A to get as close to 6200 RPM as possible at wide open throttle with a light load (just you onboard with about a half tank of gas). You shouldn't take your new motor up to full thottle except once after the first 5 hours of break-in, and then continue the break-in procedure. I found some performance bulletins on the Suzuki website. Looks like you could start with the 20 pitch, but might need to move up to the 22 pitch. Here are the performance test results that you could compare with the size and weight of your Hewes Light Tackle: http://www.suzukimarine.com/Product Lines/Outboard Motors/Products/DF140/2012/~/media/Marine/BoatBuilders/TestResults/S/Sundance Boats/Spyder FX19 DF140A http://www.suzukimarine.com/Product Lines/Outboard Motors/Products/DF140/2012/~/media/Marine/BoatBuilders/TestResults/S/Sea-Pro Boats/SeaPro 208 DF140ATX http://www.suzukimarine.com/Product Lines/Outboard Motors/Products/DF140/2012/~/media/Marine/BoatBuilders/TestResults/B/Blue Wave Boats/Blue Wave 1902 DF140A http://www.suzukimarine.com/Product Lines/Outboard Motors/Products/DF140/2012/~/media/Marine/BoatBuilders/TestResults/S/Sea Ark Boats/Sea Ark River Cat 180 DF140 1 Quote Link to comment Share on other sites More sharing options...

geeviam Posted February 27, 2020 Report Share Posted February 27, 2020 You're welcome! Congrats - I think the Suzuki 140 was a great choice! Anxious to hear how it runs on your rig. 😊 Quote Link to comment Share on other sites More sharing options...
Shallowminded6 Posted February 27, 2020 Author Report Share Posted February 27, 2020 Me and you both man! I am almost done getting the boat ready. Waiting on some stuff to get out of powder coating. Will post some stuff up on people I used for parts and the repower. Numbers etc so it is easier for others. Was happy I had the responses here. Really helped me with my decision. 1 Quote Link to comment Share on other sites More sharing options...

Really helped me with my decision. Awesome! Just checked the prop slip calculator, with your new setup. After break-in, with a light load, if you can turn the 22 pitch (cupped) prop at 6200 max recommended RPM, with the 2.59 gearcase, with 6% slip, your boat should top out at 48 mph. Just speculation of course, but fun to think about... https://www.go-fast.com/Prop_Slip_Calculator.htm 1 Quote Link to comment Share on other sites More sharing options...

Havent really tested top end other than a few seconds. Top out is 46mph with a 14x20 pitch. Hole shot is on point. Havent ran with live well full yet, but had full of fuel and me on board (#200). They said that I could potentialy raise the motor 3/4” but would hit platform, or go to 22pitch and lose some hole shot but they believed the 20pitch was gna be good. Supposedly the top end could go up some after break in. I am deffinently in unchartered waters here. Thanks for all your help man. Quote Link to comment Share on other sites More sharing options...

I was excited for you when you decided to go with the Zuke 140. Sounds like it will be a good performer, and from the looks of it in the picture you posted on the other thread, the stern sits nice and high in the water with the boat at rest (no squat & a good shallow draft). The whole setup looks awesome! 1 Quote Link to comment Share on other sites More sharing options...
