hi, many thanks for the quick replies.

we do love our Hardy and im considering keeping it but suspect when we get a new rib it might feel a bit neglected.

I hear what people say about two strokes
But surely an equally matched 4stroke is equally capable of shifting the boat allong when it finally builds the revs up?
Would they not be better when the boat is heavily laden?
Are they not more economical over longer periods?

Does the choice in the end not boil down to personal prefrence when the stats are so closely matched as people are saying? or am i missing something?

just asking the questions but my mind is set on 4 stroke.... unless i can be convinced otherwise


As for the boat... i suspect the size in the end will be 6.5m
just not sure of which lump to stick on the back end

suz 150 should push the boat along with all people and gear in - would there be any power spare?

or

suz 175 - its heavier but is the weight justified for the extra push?
will there be a little bit extra power for fun days out etc?

thanks again
Kim

The 150 and 175 both weigh the same,put the 175 on. My Rib manufacturer wouldn't put the 175 on as the max for 5.85 hull is 150 (they thought I was a nutta)..

hi, your dead right suz df 175 is same weight my mistake.
The xs 650 is rated for 200hp max weight 360kg so well within limit but will i be under powered with all the family and the spare kit that brings for extended cruising?

i'm pretty much convinced but an expensive mistake if i get the set up wrong or leave myself underpowered.

I've got the 150.

Around the 0.75 ltr per Nm

46knots.3 blade 25"x14 3/4



Playing around with a 4 blade hydromotive prop at the mo,beautifully finished prop with PSV vents etc ...did 42knots ..It's my fault as I asked them to take into account the weight of the 150, so the prop is a stern lifting prop.

I've only tried it once, I trimmed out the same amount as the original prop resulting in the bow ploughing at over 40 knots (the steering was a bit like herding cats).

they have suggested trimming out further which is the plan for tomorrow. Presently, sick as sea going parrot

Why not go for a Soozook 200?: V6 3.6 litres ,263kg, so well within weight limit, loads of grunt......

Have you checked prices? (buying prices, not RRP) As they get bigger, the price differential tends to narrow.
As a guide, Soozook's 2007 RRPs are:
DF140TX: 9149
DF150TX: 9699
DF175TX: 10499
DF200TX: 10999
Take these with a pinch of salt though, as nobody pays RRP - well, nobody needs to, unless they're a salesman's dream.
The biggest joke of that lot is the 150/175 differential, for basically the same motor
DF200 looks the best value to me, for a hull rated to 200hp

Good point - and a 200 would need less throttle than the others for cruising!!!

Hi, I have spoken to her that must be obeyed and in principal she is in agreement that extra for the 200hp could be found - where she finds the money Id love to know.
In terms of economy how much more would you expect the 200hp to burn?
A difficult question to answer specifically but rough estimations would be very helpful.

Have received quote for the boat and delivery is estimated October.... as you can probably imagine I is getting excited
