Fraser is one of the most dangerous rivers to run ,with debris and current to deal with
Are Sharrow Marine propellers worth a try.

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 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.

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

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.

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

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.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.

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.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.

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.
Sorry...so damn busy...but want to do proper report. Their customer service has been amazing. Fuel mileage not where it should be but every other aspect of the prop is honestly so much better than a normal prop, so hope we can figure out if it is the pitch or what....which they are working with me on and said dont worry about the 30 day thing, if don't want it at end of it will refund. I'm very impressed by their customer service so far...will go into way more detail when have time but holy crap on day 17 of 18 in a row and 30 of 33. Other than fuel mileage (in rough seas way better fuel mileage as it just plows and pushes, almost like a diesel inboard) this thing is way way better....will give more info later....but not worth the 10k for same or slightly worse mileage...again, they're working with that with me.
