Are Sharrow Marine propellers worth a try.

[SpringFever2359]

if you spend any time in the fraser you will tag one, i never seen the wood that bent that set of props

Fraser is one of the most dangerous rivers to run ,with debris and current to deal with

I wanted to believe in this but watching the guy do trials with a boat that had an electric motor where energy use could be accurately tracked did not show any difference.

I went down the Sharrow rabbit hole on Axopars for my buddy, I believe there are no examples on their website of an Axopar with increased range because the mercs they come with and the hull shape are very efficient, and the people who have tried them haven't had great results. My guess is the same for a C-Dory, but we'll see how my new prop and engine perform. Definitely cheaper to re-prop a single 150-200 than dual 300's. Be interesting to see if you can get any deals right now. Lots of rich Americans aren't feeling any pain, but some I've talked to are feeling fear, and some are in pain financially. If you take away 25-50% of Sharrow's customers, it will end badly. Hope you guys land your pursuits and some great props either way.

I ran the numbers a few years ago and ended up figuring with my hours I put on my boat and projected fuel savings it would take me 18-20 years to pay for the additional costs of the Sharrows vs regular stainless. I could see though with high usage, big motors, big weight and big fuel burn it may not take too many years to pay for them.

Is that on the Internet? It would be really interesting to see the results/data from a test like that.

It's the longer range and better handling that are attractive to me and others. My buddy runs from North Saanich to downtown Vancouver and has to stop to fill up on the return trip, to give himself a safe margin of error. He has a single 350 Merc.

Sharrows are more reasonably priced for those running single engines, who are repowering and don't have a prop yet. If I could even get the factory-tested OEM prop tested range of my boat, I'd have a 370-mile range at 22mph. It would make trips to Alaska through the Inside Passage so easy, not to mention trips to Vancouver and Seattle. As is, I think I'd have to strip everything off my boat to come close. Physics is tough to overcome with slick marketing.

Yeah, good point. Running a single makes it way more attractive. With my twins I would have had to remortgage the house when all was said and done. It doesn't help that our dollar is so weak now either.

The day sharrow shows up in the racing community people would be lining up to place orders... until then it's just a hydrofoil of sorts.... do I really need it and why didn't it come with the motor.

Doing 30 day trial on these starting in a week or two. Will report back

Any updates? I imagine you’ve had a few weeks on the water now?

 

[SG2.0]

Just got them put on yesterday. Took for quick spin in harbour but blowing 30kts so little hard to say as couldn’t exactly run ideally. Definitely grab impressively and can stay on plane at low rpm like I’ve never seen which in weather would save fuel. Little worried at 27-28kts (normal cruising speed) don’t see much gain.

Gonna use em next couple weeks and report back

A pair of Sharrow's on a 34' Kingfisher at GI Boatyard.

There's a recent post of iFish.net about someone who tested two different Sharrow props against two different "standard" props on a Duckworth Offshore with a single F250.

Sharrow Prop Test Results

Here’s my experience with Sharrow. I tested 2 sharrows. Boat is a 2016 Duckworth Offshore with a single Yamaha 250 nizpro tuned to 330HP. I was running a 13 pitch 3 blade Salt Water Series 2 prop before testing. All tests were an average of 2 runs. Performance numbers from testing Sharrow #1...

TLDR: one of the "standard" props worked best for him and he wasn't happy with the customer service.

Somewhere on here, it was mentioned that Yamaha is gonna carry them as a line. With their global network and a reasonable customer service reputation, that could benefit this invention.

Interesting comment in the article about the minimal if any performance improvements when the sharrows are up against a quality 4 bladed prop. Maybe not so worth the 3-4X price tag of a regular prop.

In the limited real world data I’ve seen published so far it has been apparent that where the big gains have been experienced with a Sharrow prop, the boat wasn’t optimally fitted with a ‘standard prop’ in the first place. It’s a common marketing ploy to compare apples to oranges to get a desired result.

 

[Rain City]

I just think the biggest gains are seen in the wrong RPM range. Nobody operates their boat between 2500rpm-3500rpm. And I believe that's where they were most efficient. That was my take after three years of beating this poor old ******* anyway.
