Performance data questions

[NCLakeboater]

I'm looking to purchase my first boat an Azure AZ210 for a lake where we live in NC. We plan to use the boat for pleasure cruising with occasional use pulling a tub and wake boarder. The boat is packaged with the Yamaha F150 outboard. There is a Yamaha performance data sheet on this same boat and engine on their website. I'm don't really understand the performance data and could use some advice on what it all means, especially on the highlighted 4000 and 6000 RPM data. It appears they used an optional Yamaha Reliance prop in the test, is something I should also consider?

Re: Performance data questions

well it looks like the data was with a 225, not a 150 so it would have no relevance to your situation.

Actually I thought that at first as well when I read it, but the 225 is the listed maximum HP. The tested engine was the F150TXR.

Re: Performance data questions

4k rpm is highlighted because that is the most efficient rpm (most mpg's) and 6k rpm because that is the rpm at WOT for that prop/motor (F150 in this case)/boat combo.

The reliance props are pretty good and might be a good choice for that boat. But, if you are buying new be sure to get them to agree to swap props if you can't hit 5800-6100 at WOT on your boat. Take the published performance data as a reference point only, and not a gospel.

I'd be very tempted to hang a Yammi F200 off that boat. Great motor and might be more economical at cruise, too.

Thanks Bamboo. Do those numbers look OK from a performance standpoint? Also if I went with the heavier F200 would it tend to plane easier and would fuel efficiency tend to increase or decrease?

Re: Performance data questions

Follow up question. If I was to consider the 6 cyl 200HP Yamaha over the 4 cyl F150 is would there be more maintenance costs?

Thanks

Welcome NCLakeboater! So what lake do you go to?

Not really, I would go with the 200 if your budget allows it...

I live on Lake Auman in the Seven Lakes area outside of Pinehurst, NC. Sorry to keep asking more questions but I want to make sure I've considered all aspects to my first boat purchase. I assume the F200 would be working at less RPMs to push the the weight of the boat and therefore the added cost of fuel burning wouldn't be too much greater than the F150, especially if I was pulling a tuber or wake boarder?

Re: Performance data questions

I would think your correct.The 200 would not have to work as hard.I doubt you could tell much difference in fuel usage.It never hurts to have that extra few horses.

Re: Performance data questions

The boat you are looking at weighs in at 3400 lbs., and is rated for 225 hp. I think that the f150 would move it OK, but I don't think that you would be very impressed with it's performance with the boat full of fuel and with with a few people onboard. The F200 & F225 swing a prop that is 1" larger (about 15" or so) and the engines have more torque/horsepower and would not have to work as hard to propel the boat. Opinions are like...well you know...but IMHO if you can afford it, I think you would be happier in the long haul with a larger motor on that boat. Take a look at this data sheet as a comparison http://www.yamaha-motor.com/assets/...lletin_4stroke_hpv6_rel_azr-210ob-f150txr.pdf
It's a bigger and slightly heavier hull with the F200 on it. The gph curves between the F150 and F200 are similar. I have a F150 on a 1750 lb v-hull and it gets about 5.5 mpg at 3000 rpm. So, if the graphs are anywhere near accurate that tells me that motor is working harder to keep that hull moving. The motor can take it, but I don't see any real fuel savings between the F150 and F200. The real question is how much more will it cost for a larger motor, and do you want to spend that?

The cost difference for maintenance between the F150 and F200 is minor. The props might be a little more (but how many times do you buy a prop) and you have to buy two extra spark plugs every couple of years, but other than that the maintenance costs will be the same as they use the same filters, etc. Get the Yamaha Extended Service plan if you can get it tossed in the deal or for a fair price. I think that Yammi has a rebate program going on right now for credit towards 1.5k of service. That should bring your service costs to zero for at least the next three years!

Have fun and Good luck with your boat purchase!

Re: Performance data questions

Just want to pop in and say Howdy.. We briefly looked at the Azure at Chatlee - Nice looking boat.
We spend a lot of our time at Jordan Lake -

I would definitely go for the larger engine if budget can handle..

Gtreat info. Unfortunately it may come down to price. The dealers I have spoken with seem to be able to make the best package deals with the F150.
