Sorry to re-hash such a well discussed topic but....
Just got the new engine on the boat today. Haven't used it yet because it came with a left hand rather than right hand control box/throttle lever.
I'm very much a right-handed guy, so will need to wait for the swap.
So, the prop that was ordered for the engine by the shop was a 13 x 13.75.
It's a 5.5m northcraft, weighs about 750kg, and will be used for a mix of diving and family cruising. THe engine is a Honda BF90 4-stroke.
All the props I've come across before - diving Club's 5m Humber/Yam 60; a mate's Delta 5.5/Yam 100 etc have been 19" or thereabouts. It was a 19" on the old Mariner that's just come off the boat, so 13.75 seems a long ways different.
I figure now's the time to swap it, as it hasn't been used, and wonder what would be the best to start off with. 19" again??
Thanks in advance.
