Prop question

[Bch53211]

Hit what I think was a log coming in tonight never saw anything and it was in a channel that I’ve come through dozens if not hundreds of times. There is a heavy vibration when I throttle now. Pretty sure I’ll need a new prop. I have a ‘19 Helix, looking for suggestions for the best surf prop.

[996scott]

can't help you on what prop to get but if you haven't thought of it already, get that one fixed and keep it as a spare.

[Bch53211]

Yes thanks for the suggestion. Maybe it’s not necessary to replace, I’ll see what the dealership says once they get it in the shop.

[KnoxMojo]

15x12.5 by OJ is great. Contact them. They will sell you a new prop and fix yours for free if it is repairable.

Don’t use nettles to fix your prop, they are overpriced.

Just what I was looking for thanks for the suggestion.

What are the advantages of certain props from a surf perspective? Mostly better fuel efficiency?

Pitch is a trade off top speed and pulling power.

I could careless about top speed personally.

But for surfing at full weight, the lower the pitch the more pulling power, but if you lower pitch, it raises operating RPM.

If you can find a prop that pulls big weight and keeps rpm’s at 3400-3600, you are doing great.

as far as prop repair, most larger cities have places that will repair a nibral prop. personally, unless you need to do something else at the dealer, they are not hard to take off, get repaired and put back on again. it was $90 for my last repair but that was a minute ago. sure it's more like $150 today. dealer will likely charge labor to pull yours off and add a markup to the repair invoice so be cautious of that.
most local shops can fix a prop if dropped off on a monday, will have it back to you on friday based on my past experiences getting several repaired over the years. it's the dealership that can hold up the repair waiting for it to get into the shop.

I really like the acme 1235. great prop to surf with. had it on several boats and would buy it again in a heartbeat. nettles is one of the best places to order a new prop. good pricing and they can offer suggestions on what to swap over to based on your boat/engine/needs.

[larry_arizona]

Nettles has great new prop prices, just awful repair prices even with a $50 coupon and no quote until you ship it there. It is a scam for repair.

I have an oj surf prop on my mondo. Will get you numbers off it this evening.

Helix is 20ft so really you do not need to be over the top.

ACME 1235 came on my MOJO and worked great until with upgraded bags, lead, etc. Once I put 11 people in the boat, it needed a little more grunt.

I suspect it would work great for your Helix considering you are 20ft and won't have as many people.
ACME 1235 - 14.5 x 14.25
I currently have a OJ945 - 15 x 13 <-- not sure you would need to be this aggressive.

[larry_arizona]

Pretty sure a 19 helix is a 400/1.76, guessing current prop is at least a 15.5 x XX

The prop that came with the boat, it’s a Nibral OJ 14.25x14.5 four blade.

[Holdmybeer]

Go with a new WakePro V4 prop OJ 1951-MF - 15" x 14" pitch.

Keep your RPM's down, moves weight, and still keep your speed.

19s were still the 1.5 gear ratio, unless late year Supra 450s.

ACME 1235 or OJ 945 would be great on your Helix

Interesting comment on Nettles. Used them years ago on my 2007 Supra, sent them a pic and called them on the phone. They quoted me a new prop price (cheapest I found) and the repair price. It was the same ACME model prop.

Worked out good for me. Sent me the new one, I used the box and shipped the bent one to them, they send it back all repaired with a T-shirt, extra nut and pins.

Since I'm in Knoxville, I would use OJ anymore.

Shipped to them, $20, they quoted me $360 to fix a small ding on two blades then took $50 off, $310 shipped back. So minus shipping it was $290 to repair.

Local repair next time.

Ouch . . . .

Could be the going rate in this climate, but expected maybe 150-200 tops with $50 off plus shipping.

hate to say it but you grabbed your ankles on that repair.
should be, as you called out, in the 150 range.

150$? I’m certain my dealer will charge more than that. Hard for me to take to someone else, I don’t have a tow vehicle and dealer usually just picks up my boat for me. They charge by the hour wondering how long prop repair should take.

Barring a stuck prop, it takes inside of 5 minutes to remove a prop. Get a quote on someone to come to the boat and remove the prop and reinstall it once its back from the repair shop. Or, if you are handy with basic hand tools, purchase a prop tool and remove it yourself and send off for repair.

Speak with Jim Thelen at ACME. He will ask you a few simple questions to give him an idea of how you use your boat and where you use it. A great guy with a ton of knowledge regarding choosing the right prop. He can direct ship you the prop and a puller. Takes about 10 minutes to swap with simple hand tools. [email protected]

Thanks Tommy I will do that.
