Help with SS Prop

[lundluvr]

Toying with the idea of replacing my aluminum prop for SS. Other than the extra cost and being more susceptable to damage what benefits should I expect. Hole shot, top end speed etc? I have a 1800 Pro-V with a 150 opti, three batteries,40 gallons of gas and usually 3 people to push.

Any help for pitch would also help. Thanks

You should be able to get better holeshot and higher speed... the better holeshot because the prop blades won't deflect like they do on a aluminum prop, and higher speed because the prop will likely be cupped more than a aluminum prop.

As far as what pitch you need to provide more information... what pitch prop are you running now? What RPM are you turning at wide open throttle?

I will check for sure but does 13 1/2 x 19 sound right.

I know I run about 5250rpm trimmed out and wide open.

Thanks

You are probably going to lose a little RPM on the top end mainly cuz the stainless doesn't flex and lose pitch like Aluminum. But on the other hand if you are in mid to upper portion of the RPM range for the motor you should gain a few MPH on the top end cuz of the no flex.

You have a fairly common rig, make a couple calls to the dealers and they should be able to tell you what pitch is best! I'm guessing a 17 pitch should give you a good ride!

Try Jay Soderbloom. He will let ya know what he thinks would be ideal for you.

Make sure you know things like size and pitch of old prop, alum or ss, how holeshot is, top end speed, where your ideal trim level is at top end, rpms at top end, boat type and motor size etc.

I get all my props done by him and his prices cant be beat.

He also does custom prop work. I had a prop done by him and man did it make a world of difference.

Jay is a straight shooter and wont fill ya full of bull.

Give him a call. While your at it pick up a Fishbright for your Coleman Lantern. www.soderbloom.com

I have an 1800 with a 150 Yamaha VMAX. I run a 21 pitch SS prop. Fully loaded I get 45-47 WOT at 5400 RPM's. 52 top speed at 5600. With my 21 alum. prop I top out loaded at 45 and 48 near empty. I don't notice much difference with my hole shot. Unless you just want to spend some $$$$ you don't really have much to gain. You also up your chances of damage to your lower unit because an SS prop doesn't have any give. I hit a gravel pile at 5 MPH and bent the shaft. An alum. would have rolled over. $50 for prop repair instead of $500 deductible. I'm ordering a new boat in Jan. without the SS.
