i would say the 175 , if proped correctly it will give you good economy and have decent power .
the 150 4s is a good engine with better fuel economy but i would think underpowered on your boat
Tough question Winnie - really depends on what you are going to do with it BUT given the size of the boat and the fact it is a whitley I would go with the 175, the 150 would be a little light on power (IMO)
cheers
winnie, if you can afford it go a bigger 4s. the 175 would be min size on that size boat and with the future resale of a 4s on a nice pleasure boat like that, you'd get a good chunk of the money back when the time comes to sell.
Winnie, I have the 200 HPDI on a 615 Yalta and would not consider a 150 4banger on it.
Fuel economy is good as well as long as you are not silly.
Last weekend I put in at redland Bay went to Macleay, Peel, Green, st helena, Mud, st helena, green, manly harbour, peel, macleay and back to redland bay on an overnighter.
Averaged around 55k's per hour, filled up on the way home and the boat only took 34 litres.
I thought that was fantastic for a 200. Saying that, it is not really working hard doing 55kph.
doing 80+ k's per hour, I really do not want to be filling up at the end of the same trip !
but it is capable of it at the same time.
that's good economy mtx. my mate has got a 200 v6 4s on a 6.2m hh and can get down to 15-20 lph in good conditions. he's going pretty slow (35 or so km/h) though to get those figures
If going Yamaha i would definately go a larger four stroke over the HPDI. Do a goolge search "yamaha hpdi blown up"
personally i would be going the 150 4s. they have a great reputation and there are huge numbers of the on US boats. my mate has 1 and loves it.
the HPDI's do not have the same reputation IMHO. as hino said search "blown HPDI" and there will be a bit more info for you.

I'd stick with a 4str but as paddles said, go bigger if you can afford it, a 150hp would be underpowering. Having said that, Why only a 150hp 4str, besides the price, is there a transom weight issue? Or just looking to save some hard earned?
I would be going the hpdi if they are run in correctly they give no faluts at all. They are better out of the hole etc.
If you're gonna go with a hpdi go with e-tec instead of Yammie.
I've got a 175 HPDI on my boat and am more than happy with it. On an offshore trip I can get almost a mile (not Nm) / litre, depending on conditions.

Both are at the better end of the scale – as is clear from the range of comments above.
The HPDI is likely to have a higher fuel consumption. Taking a rough guess that the 4 stroke uses 14 lph on average then if the HPDI has at least 10% higher consumption or 1.4 litres.
Based on 100hrs pa at $1.70 per litre that’s another $240 a year or so. Maybe much more.
Glasses Guide says that you will lose more value on the HPDI. The 4 strokes retain their value better .
Over 3 years the average depreciation in the F150 is 19.9% p.a and the HPDI at 22.7%. - over 3 years that’s about another $1,000 loss in value.
Now to the emissions. The HPDI is a 2 star and the 4 stroke a 3 star, with about half the emissions.
You may not keep the HPDI for ten years - but it should last that long. Given 100 hrs pa and ten years the HPDI will put out an extra 2.7 tonnes of emissions. It always sounds a lot when I put it that way - but that’s the decision you are making.
We will likely have emissions regulations in the next few years. Under the standard they are considering, the HPDI wont pass. But don’t worry about that – the regulations will only effect new sales - not the outboard you but today. In other words there is no “ban” just a new standard for imports.
Probably more information than you were seeking – but there you are.

PS teh transom weight difference is 18kg - less the tank of 2 stroke oil.
If your going to keep the boat for the life of the motor eg 10 years / 2500 hrs get which ever you please but if your planning to upsize, downsize or sell up in the forseeable future the 4 stroke will give the whole boat package a higher resale!

Alcohol doesn't agree with me, but i sure do enjoy the argument!!!
Don't even think of putting a 150 4 stroke on a 6.5 metre glass Whittley,it will be so underpowered pushing 1300kg + fishermen + gear + fuel.
I take it,it's the SL 2200 which has a max hp rating of 225hp.
If it were me i'd spend the extra $$$ and fit at least a 200hp as it will get on the plane easier and it won't work as hard as the 150 or 175.
I'd go the 200 VMAX,whats the price difference between the 175 and 200?
The 200 hpdi is one of the best motors ever made and they sell millions of them in the States and they are the best match for the Regulator and Contender CC's.
If you are spending this much on the boat,don't scimp a few $$$ and underpower it,it will piss you off everytime you take it out believe me.
A tip on the VMAX,the black stainless props are the same price as the chrome VMAX and SWS props,so tell the sales rep you want it fitted with a chrome vmax or SWS (Saltwater Series Prop) The black stainless props chip a lot easier as they are a weaker grade stainless steel.
For memory the Vmax prop was $970 and the black prop wasn't much cheaper,that surprised me and also surprised the Yamaha rep.
Let us know how you went tomorrow.
