polliwog Posted August 17, 2019 Report Share Posted August 17, 2019 As the title says I am looking for some answers on propping a new 150 Yamaha. Engine came with a "standard" stainless prop, I don't have the pitch,but it gets out of the hole just fine and runs great up to 4,500rpms. When I try to trim the boat I can't get WOT throttle with out the bow wanting to plow even though I'm trimmed out to the point of blowout. Obviously there is no trim tab causing this they are in neutral position. I need a prop that will lift bow if that is possible. Boat has a trolling motor on bow,but no other extra weight up there. Full fuel tank and just me running solo. BTW no water in the live bait well. I guess I'm asking what 20Lt owners are running on their rigs.

smboudreaux Posted December 28, 2019 Report Share Posted December 28, 2019 Im running a powertech OFX19 3 blade on my lt20 with a Yamaha F200XB. Turning up about 5700. I dont have any issues with plowing. I cant trim up high enough to get the motor to blowout. I'm on running 48-50 wot so i know i've got my own ghosts to fine. Idk man. I'm curios to hear what you come up with. Quote Link to comment Share on other sites More sharing options...
bigsnook35 Posted December 30, 2019 Report Share Posted December 30, 2019 The characteristics of the LT are for it to run bow down. To fix that problem you would have to do bottom work to the boat. The faster mine goes the more boat in the water. Also makes the boat ride great in a chop. Quote Link to comment Share on other sites More sharing options...
polliwog Posted January 15, 2020 Author Report Share Posted January 15, 2020 sorry I've been away for a while. Big snooks, What do you mean by bottom work.? I have read somewhere on this sight that there are props that provide more lift. I've never had a boat that wouldn't lift even some as it was trimmed. At 40mph it is fine,when I add power you can feel the bow start to plow. The only thing on the bow area is a Troller. Batteries are in the consol. I'm not a speed demon,so it's not like I want to go WTO all the time. My 150HP VMAX didn't do this as much. Quote Link to comment Share on other sites More sharing options...
Ksayles44 Posted January 16, 2020 Report Share Posted January 16, 2020 I have a 1996 Hewes LT 20 and an '06 Yamaha F150. OFX3R19PCLYX200 Port 3/8" That is the prop I am running after talking to the guys at Powertech. Love the prop and much better than what I had on it before. Great all around performance and I see ~45 on gps with me loaded up. Probably could squeeze some more out of it running light. 1 Quote Link to comment Share on other sites More sharing options...
polliwog Posted January 17, 2020 Author Report Share Posted January 17, 2020 Thx Ksayles, I'll check it out . I'm also now wondering if I may have the motor too high and it doesn't allow enough to trim to lift the bow. Speed isn't the issue ,, Another thing to think about over the winter.
