Winnie, I think the decision of whether you go DI 2 stroke or 4 stroke gets down purely to which technology and features you prefer, but like others have said, if you go 4 stroke, a minimum of 200 ponies would be the way to go.
Not sure what performance you want from your boat, but having a rig that is sluggish and underpowered is a real dissappointment when you have shelled out a small fortune!

Mate, the badged 150 4 stk yam is actually 163 hp so there is only 12 hp difference not 25. the hpdi is good, nearly put one on my boat, missed it on ebay, went for a 150 efi merc - good reliable and tough motor, but thirsty 36-38 lts/hr @4000 rpm 180 lts to the rthern banks and back. Now have f200 yam 4stk on a 6.5mt platey - 18 lts / hr at 4000 rpm 90 lts to northern banks and back.
I'd understand the 175 hpdi is in a similar ball park on economy to the 4stk.
Your call I'd reckon, nearly much of a muchness - for me, I'm sold out on the 4stk, but have a few more neddies up my sleeve and ony on the odd occasion have they come in handy, but when I've needed them, they've really helped
cheers

Thanks Jack for your info. Really helpful.
Been at the boat show today and after reading the posts I put a line through the 150 4 str and 90% sealed the deal on 175HPDI. I will check out the price difference on the 175 to the 200. Down herenot a lot of HPDI get moved so its hard to get decent info like yours and a few others.
Interesting to note that I just happended to have a chat to a Suzuki dealer who absolutley shit canned the Yammy HPDI models.. Then spoke to a few less biased dealers who balanced it out. Thanks again.
Not looking to save any hard earned cos there is none left nowOriginally Posted by Scott nthQld
but looking to max out on power and minimise on $$$. Hard task. The dealer was more than satisfied with the 150 but again no fuel/gear/passengers makes a dif.
Cheers, quite a few blokes have said underpowering would be an issue.. up we go.
Winnie,that's great news that you've decided against the 150,especially being a 4 stroke.
That Suzuki rep is a real tool,they'll say anything and i mean anything to make a sale.
You need to be wary about dealers underpowering boats to keep prices down,most dealers do it to make BMT packages more attractive and if a customer is financing,it lowers the monthly repayments.I know a Gold Coast dealer which i won't name,who sells a 6.4 metre hull with a Honda 130 4 stroke,it's absolutely insane when you load it up with 3-4 adults,gear,eskies,fuel.I said to the dealer while i was looking at the hull with the 130hp,"that's so underpowered with the 130 for that size hull" He looked at me nervously and said it goes well.
Get 3 prices for the 175 and 200 Vmax and play the dealers against each other.Dealer x can do it for this,can you beat it,sales reps love lies so say your best price is lower than what it is,all they can say is no.In these times of high interest rates and high petrol prices,motor sales will be down,so you should snag yourself a nice deal.Do the same with the hull to.
All the best and i'd love to see some pics.
Winnie,
I have just powered a 625 Cruisecraft with a 175 HPDI. I did all the "blown motor" searches on google, and did a lot of asking around prior to taking the plunge, then I did more google searches on all the other brands of outboard and you wouldn't believe it.... I got hits on all of them!!!
I have only racked up a few hrs on the new boat, and due to the crappy weather during the few days I got to use her before putting her to bed for a couple of months, I could not get any really accurate fuel consumption figures.
I did take the squeeze for a run to Tangas from Scarborough though and for a 72km round trip used 46 litres, mind you we did quite a bit of idling around looking at the sights so its still not a very accurate calculation.
Now just got to hope the weather is good in September so I can get her dirty.
Having said that, knowing what I know now, I think the 150 4stroke would have been underpowered on mine, and as yours is bigger, I think its wise to go bigger in my humble opinion.
Good luck mate,
Shane
just to add another aspect that is relevant to what shane has said with the cruise craft is the weight of the engine . the 625 cruise craft responds to trimming and ride so much better with a lighter engine that i thought should be considered for winnies whittley ( how about that for your boat name ).
i have a cruisecraft 625 as well and i have a had 2 engines , one wieghing 238kgs and the other 194kgs and the difference in handling is substancial
food for thought in your decision and dont let that suzuki rep put you off that brand , if you are thinking of a brand change , i would give the suzuki serious consideration in the 4s class .
Cheers Shane..
I have traded in a Cruisey for this one ( 500 Exp). I had a look at the rig you have and they are awesome. Great fishing deck. Awesome price too..After having a CC for 10 years though its worth it Im sure..
Did the search as people suggested and very little came back recently.. a lot from 2004 and 2005 but nothing from 08. Same models probably with a few alterations to the fuel output to stop them "blowing".
if you have a pic of your rig all set up I'd be keen to have a view as I havent seen one decked out like that. Good choice all round I hope.
Cheers
Winnie
The next post was looking for a name, just saved me the trouble Marco, got it covered already.. nice one.just to add another aspect that is relevant to what shane has said with the cruise craft is the weight of the engine . the 625 cruise craft responds to trimming and ride so much better with a lighter engine that i thought should be considered for winnies whittley ( how about that for your boat name )

Weight was an issue, but my mail is the 2 motors exactly the same weight? didnt sound right originally as I thought the 4 Str would 20 -25 kg heavier. Not sure if Yamaha list their engine weight as is on set up or out of factory.
Dry weights of the comparable XL shaft versions are identical at 220kgs. Nothing in it.
The 175 HPDI is the same motor as the 150 hp and 200hp HPDI models (2.596 litres). It is also the same block as the EFI 2 stroke 150, 175 hp and 200hp models (Precision Blend). The 150 4s motor is unique to the 150hp model (2.67 litres). The next 4s up is the 200hp which has a 3.352 litre donk and weighs 269kgs (dry). Only the Opti and E-Tec are significant lighter (190kg and 195kg respectively) unless you go for an old tech 2 stroke.
The 175HPDI should be able to cruise at lower revs because of the extra torque at lower RPMs, probably 3500 to 4000 rpm will be the most economic cruise. The 150hp will need more revs probably 4000 to 4500 for similar cruise speed and economy. If you run the HPDI at higher revs ie. say 4500 rpms or more then it will start to use measurably more fuel.
It is important to get the engine set up correctly, ie right height on the transom and the correct propping. This is where your dealer's experience comes in. DI 2 strokes seem to respond the best to a good set up, but it is important for all styles of motors.
I don't think there is going to be a huge difference between the 2 motors, more power is always better but they are of similar displacement and weight, so as long as they are set up properly and driven to suit there engine characteristics there would probably be no more than 10% diff in fuel economy, speed etc. You would probably have to go to 200hp to see a really noticeable difference. This is also the hp range where weight differences between the 2strokes and 4 strokes really surfaces.
Have a look through the F & B tests on Seamedia.com.au and you will see what I mean;
