300hp Outboard Current Market Costs - .....

[mustang5]

Cormorant,

Price difference between single 300 and twin 175 is roughly 10k.

With regards to the 250, I made do with a 225 but had to limit weight in board to 3 pob. Plus cruising was either at 27 knots, or not on the plane lol. The 250 had a great hole shot, but again it was either cruise at above 4500rpm or it's buried in the water.

I need something with a bit more ticker to be able to spin a larger diameter prop to get a slower plane speed.

I would only be saving $4k between a 250 and a 300. Considering the transom seated for 400hp, plus a lot of overseas reviews on 300s have been really good.

Now just trying to analyse the technical differences of the two motors. Things like real life fuel figure comparisons on similar boats.

Does the Suzuki larger prop diameter play a part in lower speed planing?

Does the Suzuki lean burn system really save the amount of fuel that they claim?

Given each trip I do up here is around 400km round trip, fuel usage will be a little more important than if I were only doing 150km round trips so to speak.

The kicker thing is more so for peace of mind... Its a very clostraphobic feeling being out at sea with no forced momentum, even if it be 2knts against the tide lol.

Apollo, come the 4th time mate, you tend to know how to make the missus feel sorry for you and give in quite easily!! Takes some hair pulling, Jim beam out of the bottle, midlife crisis talk with plenty of boat cleaning in between to make it all come together!! Haha

I know u want a 300 but http://www.boatpoint.com.au/accessor...d=141CC842F593

Funny you say that Owen because I had my boat next to a 26 striper at the ramp the other day and they looked similar in size.
I get 1k/l at a cruisey 4300 rpm. Thats about 44k/h and at WOT I've stretched it out to mid 80k's/h but that was really trying, clears off, no gear and 2 people hahaha........

Is that ALL

Makes a bit harder to go any faster when your boats not made out if balsa wood and PVC glue....

Looks like were on then

Better see what else you can chuck out of it then

Looked at those. How are Demo outboards usually treated??

Whats the fuel figures difference between twins and a single?? Going from twin 200hp optis on one boat to a 225hp yammy on another was the difference between a trip cost of $800 and $380 lol. Sure different boats and the twin setup was about 900kg heavier, but still.... I need some convincing.

Just get the ECU reports from the 175's to see how they have been driven

10-15% more with twins

While the 10 to 15% for twins is probably right what about the situations, that I often find with my twins, when I turn one off and just use half the horse power; ie for slower operations. As I do a fair bit of slow running I suspect I am not using the extra 10 to 15% and during mid range the fuel consumption seems very reasonable with the two and tall props ie 20 p

I don't know how yammha do their demo motors but other companies start the full warranty period from time of fitting on your boat. They are usually well fully serviced but you need to check costs of fitting and all the extras you need. ECU now will show just what hours and how hard they have been run and dealer warranty record will show if it has had any work. You get a run in motor that will have been well set up on a boat but you do need a decent discount . Honestly with 4 stroke and fresh oil not may people are wearing them out. the only thing I see with demo motors is that they may not be flushed but being regularly run and a check around thermostats on fitting ?????? Are the torque curves avaliable and comparable between the motors? Compare it with a 250 as well. Peak HP is still a bit of a misunderstood thing.

Would be interesting to see on the same boat real world results of the twin 175s and a 300 as the twins would lose 25hp on extra prop , leg in water and weight so would be a good comparison. As for prop size and yadda yadda it is a mixed bag in my opinion on different hulls and different props. Theory is a big slow turning prop is more efficient at some speeds - reality hmmmmm and what props are available.

I have top say only a man who has not been outside radio range with a kicker running would ever believe they can make 2 knots against any current or wind. Go single ( or even twins) buy a sat phone if outside radio range anyway and use it's data link to confirm weather if staying out.

Some big Zukes were having corrosion issues but not sure why so I'd be checking that out to confirm if it is set up , electrical or a metal problem. . Please ask the zuk dealer what " lean burn" is and at what revs it effectively saves fuel. If you don't fit that profile ignore it. I'd love to hear his marketing explanation.

Thanks fellas.

I've got about 10 prices back today, and i must say I'm surprised at the price difference between the suzuki and the yam.

Going into this I thought the Suzuki was cheapest, but I can get a yam fitted for 2k cheaper, with the better digital gauge setup... Certainly swaying my position, along with the feedback of aftermarket support..

Yam prices are consistently low at the moment:

Ive got 600 hrs on my Yamaha 300hp in 16 months and love it, great on fuel and they are a reliable and proven model.

Sam Wallrock is a great guy, I bought my 200 Suzuki off him. I'm sure he can give them details himself, but in the case of my motor, he imported a new Contender with the 200 Suzi on it, but a local customer wanted a bigger Yamaha, so that's what he sold it with. He might so give you a fair trade for your motor.

Going by this comment alone, I think twins are going to be your friend.

[cormorant]

Shame you aren't a little bigger
These are now at the USA boat shows and with closed cooling I like em but at 500kg. basically a KG a hp same as the 300hp

Now I'm sure a little diesel would fit under that cowl?? A LS9 at little extra weight 700hp would but would a gearbox and drive handle it?

wonder what they can do about pricing.

I'm currently contemplating the same options for my boat. My set up is twin 115 suzukis pushing a 2.5t (dry) hull. They do the job ok but when I'm fully loaded it struggles thru the troughs. I had my heart set on a yam 300 but after speaking with yatala yamaha they tried swaying me towards the 250. At first I thought it might be an attempt to impulse me into a quicker sale with a saving of 5k, but after much research and looking at a lot of performance reports it really does look like the better option. The new 4.2's are exactly the same block, the 250 actually puts out about 265hp vs the 300's 285 or thereabouts. And only when you use premium fuel will you squeeze the extra hp out of the 300, which for me is never.. The performance reports using the exact same hull (Grady White 235 from memory) were almost identical except for the last 1000rpm where it squeezed out another whopping 2mph. Mid range cruise, trolling etc all pretty much exact same with same mpg as well. Anyway at a saving of around 5k I think my mind is made up. As much as the macho man in me would love that "300" sitting on the transom! Bit of food for thought..
