Hi Royce,
I have a Parker 285 HS Blythe Spirit with a Kiwi Feathering prop.
It's great!
I have my engine and prop serviced by John Cutler at Thornham Marina Emsworth.
John is a Yanmar main dealer and service agent for Kiwi props.
He is a very helpful guy! I've known him for over 30 years.
Give him a buzz or send an email.
Kind regards
David
