Zuke 140 props
 

Anyone running a Zuke DF140 on their 20SF? If so, what props are you using?
Thanks!

No one has a suzuki DF140?

Two that come to mind are former owners but perhaps they recall what they were running...Trayder and Mark. Maybe you could PM them?

Thanks ScottM!

Capt. Lloyd also has a 140 Zuke on a 20 sf, with a bracket on it. Unless your min planing speed is down around 12-13 mph, you might want to consider a 4B prop to get a little more stern lift to offset motor weight. 4B props might lose a couple mph top end, but will typically improve cruise mpg and reduce mid-range throttle sensitivity, especially in following seas. I think that's a good trade. You also need to make sure motor height is correct before you start switching props. Top of the anti-ventilation plate should be above the water when you're up on plane and trimmed out where you normally run.

Im using a Four blade Zuke prop 16x21 but thats for a 175foursrtroke. cheers

No problem. Are you heading out of Edg Harbor in your sig pic? I fish the Derby from shore every year and spend most of my time on Chappy so that view is familiar.

I'm running a 3 blade SS PTR Powertech Prop . It's 13.5X18P. I raised my motor, now I'm turning too many RPM's (6300+). A 19 pitch should be about right.

I hope this info helps.

I have a Df140 on a 20 foot Seacraft. I'm using a Suzuki SS 14 X 20 three blade and it will turn up to 6150 with a good load on it. Comes out of the hole easily and holds plane at 13K (no tabs). You don't need a 4 blade prop to offset this 410 Lb engine unless you're wayyyy back on a bracket. You should be very happy with this choice of prop.

Bushwacker, thanks for that. Yeah, I'm planning on shaking her down with the stock prop, then trying to fine tune. i hope to splash next week, then we can start figuring things out. I just finished installing trim tabs as well, so I have a lot to figure out.

ScottM, yeah, that's E-ville harbor. Did we exchange a few pms a few years ago regarding the Derby? Either way, shoot me one this year, maybe I can get you out on the water. The last day of the derby this year (snotty, windy) in edgartown outer harbor was an absolute albie slaying morning. I was the only boat out there until 10 am or so, and everyone missed it. Best albie day of my life.
Thanks for that Llyod!
HeadHunter, yeah, I have both batteries forward, as well as a new gas tank that has been slid a few inches forward, so I'm not too worried about weight. My old motor was about 380, so I don't think 420 or so will be that bad.
