I know it looks a bit odd on the video but from the helm I can easily see over the board in both the seated and standing position. It would be nicer if it was lower.
Hi Chris, I agree with @bostonclipper, driving on one engine up the fuel consumption of that engine to reach the same speed. Plus the steering is quite heavy with one engine out of the water. You also then have to cycle between engines to make the engine hours the same. I have done it going 'with' the tide and getting a free ride. But if you need some power stay with the twin engines. Hope that helps.
My MF895 with twin Yamaha 200's are the same. 60lt per hour at 4200rpm at 22 knots. Never went WOT as the engines are only on 42 hours. Must try it next calm day (as I'm in the UK, that may be never!).
Hi guys, great channel, direct to the point and informative. I also just picked a MF 895, with the same engines, but not hitting the same numbers. The boat came with aluminum props and are a little banged up. What props are you running to achieve these numbers? Thanks
@@TheRudder Thanks, I was told to use the Mercury prop selector, but was getting very different suggestions to the Yamaha site. Great videos on your channel keep them coming.
Awesome video..there's very few videos on TH-cam like this.. thanks for the information.. I wonder what's it like with one engine running? Safe travels 😊
I'm not an expert on one-engine operation on a twin-engine boat. It is my understanding that you would have to have a spare prop with a different pitch etc. to run a twin engine boat on a plane with one engine. So, you could keep that emergency prop on board and swap it out in an emergency if you are far from home and there is no towing service available. basically, it's convenience to get you home 3x faster than running a high idle.
Well presented and informative as usual! My 895 with twin Mercury 200s has almost identical figures - which is strangely reassuring :) With the qualification that one of my motors uses 5-10% more fuel at the same revs. (I’ll be getting that looked at.) Does the Yamaha not show consumption for each motor? And I note that your max revs showed one motor 200rpm less than the other? My max speed is 37kts
Hi Phillip, thanks for the comment. Glad to see all the figures are in the ballpark. Not sure what that differicial in RPM was across the engines. Maybe I didn't move the throttles quite together? Too busy filming and trying to keep everything else together. My max top speed is 41kn!
A better metric is using your nm/l or nm/gal. I get 1.4 nm/gal at slow speeds and just above planning speed as a general rule in our 895 Sport twin 250 Yamahas.
There is an 'efficiency' metric on the Yamaha engine computer BUT it uses an intake on the engine to measure speed (not the gps) and is widely inaccurate. The numbers end up quite same using L - I get 0.33nm/L (1.2nm/g) at 6kn and 0.37nm/L (1.4nm/g) at 24Kn.
@@TheRudder Thank you. That is very interesting. Before I dig into my Yamaha/Garmin manuals I noticed your rooftop does not appear to have a Yamaha GPS antenna. Do you have a Yamaha GPS antenna mounted elsewhere because of your low air draft?
@@TheRudder I guess I am wondering if a 2023 Helm Mater EX level 4 uses different telemetry than what you are describing? Not sure but my readings are very consistent.
The 895 is a cruiser, it can handle rough seas but probably not as well as soon others. There are plenty of people with 895s across the UK and north Europe who would experience much tougher seas than we do here. Hope that helps.
I’ve put about 5000 miles on my 895 nc sport and rarely see 1.4mpg. These hulls will average 1-1.2 if bottom painted or loaded. Top speed was 49.7 mph. Best cruise is 42mph. These boats love 32+mph, anything below that and they pound. I really want sharrow props.
@@TheRudder ok thanks. I saw from the film that it was outboards but interesting to know what size. I presume that petrol is less expensive in Australia. At £2/ltr. (dock supplied) in the UK running outboards of this size is a very expensive pastime.
@@user-oe2ti1fb8r it is around $2au a litre here. But I've definately found the outboards much cheaper than an inboard given all the running and service costs.

Nice video, great info but for me that paddle board is dangerous blocking vision out through starboard side
I know it looks a bit odd on the video but from the helm I can easily see over the board in both the seated and standing position. It would be nicer if it was lower.
If you are in an extended no wake zone, will it hurt the boat by shutting down 1 engine?
I found one engine even with the other tilted out makes difference.
@@BostonClipper thanks
@@chrisp3913 edit error should say "... makes little difference."

Good to see we are all at about the same point. Fingers crossed for that calm day!

Thank you Rob. I will do something in the future about one engine. I don't like it that much but we have had a number of questions.

I'm guessing the Helm Master system is directly connected to the GPS system (as it needs to be) so the speed data would be much more accurate.
@@TheRudder I find it fascinating Yamaha would not use the Garmin GPS. BTW did you mention the fastest you have gone?
How good/bad it is in rough waters? That is question number one...

Not the series 2, they plane at 15 knots and are smooth.
Didn't get to hear what engines you which I would have thought was fairly important in the equation?
