Dumb Question Alert!!!
Why do I get spun Props after very little use?
Here is the scenario .. twin AQ171c’s on standard OEM Volvo 14 x 19’s. Boat is a 27 foot - 30 knot sports cruiser. Weighs around 4 tons. All going well no bumps or damage, reasonably calm and flat, travelling around 4000revs - 20knots when…. Prop suddenly gives way. Throttle back to 2000 revs and limps back to port.
This has happened 3 times in as many seasons and due to Covid had very little use. The latest prop was bought new a couple of years ago and has probably less than 20 hours on it.
The first two incidents could have been the age of the props, but the new one? Unless it was sub –standard.
It could be my driving style and being too aggressive on the throttles to get it on the plane quickly or is there anything else I should be looking at.
I can get the prop re-hubbed, but keen to avoid this in the future and regain confidence, after all no point in owning a 20knot plus cruiser and sticking to no wake speed!!
