hi all
we have just purchased a 35ft hartley queenslander ferro yacht which is in need of a replacement engine/gearbox. does anybody know of a suitable combination for sale in nz ? i am told 40 to 50 hp is the ideal for this boat but very open to other opinions. it did have a 39hp buhk fitted for most of its 30 yrs but suggested slightly underpowered at that.
in case you were wondering yes we did know it needed to be replaced when we purchased, but this was the best buy in our modest price range.
up until now we have done all our boating in launches and power boats so a lot of this yachting world is a big learning experience.
cheers steve

Hi Steve,
I replied to your private message, and stated mine is fitted with a 53hp continuous at 3600 rpm Ford 4 cyl 2401E. Recently motored from Brisbane to Fraser Island , about 130nm and it only used 60 litres at 1500 rpm (5knots), I commented that this (with the Hyd Gbox ) is a large unit and intrudes into the main cabin,, and I suggest a 40hp with a mech Gbox would be more suitable, as I never use the power.
Regards Maurice... PS I have a website re the trip welcome to have a look.

Hiya, I guess a lot of it has to do with what you are trying to move ie the weight of your vessel? I have a 40ft steel keeler weighing 15 tonnes loaded & run a Ford Lees marine 60hp tractor motor through a Paragon hydraulic box. She's an oldie as is the boat (1965) but it pushes along at 9kts at 1100rpm (max) & 3ltrs an hour. A friend says put a Yanmar in at half the weight but "hello", I would have to do probabaly 2100rpm to get anywhere near the speed of the Henry (Ford OK?)and how much fuel would it burn? and what does a Yanmar cost?? There are motors on Trademe that would probabaly suit your needs?? good luck.

Yes, I would say 40 to 50 HP would be ideal. When you read the hp ratings of engines pay particular attention to engine rpm. If your engine choice gets 45 hp at 3500 rpm then you will be getting about 27 hp at the engine speed most people run them. I don't know many people that run their engines at higher than 2000 rpm for any length of time.
kind regards,
