Thanks Donny alot of good info in the video, ive just come back from a motorbike trip in ur part of the world and thought of you as I rode alongside the water I need to get back up there with my boat
Hi man seen you on the forums thanks for your answers and sharing experience. Me and mate bought our first sib with 20hp. Your answers have helped us so thank mate....... Earned a new subscriber thanks Donny lad
Thanks tam ..im still over the moon with the outboard..especially when I have to fill 3 x 25 litre tanks for a weeks usage :-D its now 2.03 for E5 up this way :-0
An excellent fully informative report, based on very real experience. I think you have done exactly the right thing Donny. The four strokes are ideal for trolling a spinner too. Do keep an eye on sea dog Fang though, as he's just given up smoking Capstan full strength behind you. As the French navy always say " To the water, it is the hour!" (a l'eau, c'est l'heure!).
Hi Donny, This is a very good informational video and very interesting. I always flush in a bin but my outboards have a built-in flush system. I have heard a lot of different stories about the built-in system. Some people say you can run the motor and some say you can't and have been told the flush system doesn't flush all the motor parts, all totally confuse me. So at least you have put all these issues to rest for me. Thanks Steve 👍
Hi Timothy ..yup..that is figues that I would expect .. the Excel Vanguard will have a lot more drag than the Alu Hull Rib I have and possibly more weigh two up which will account for the difference. Thanks for commenting :-D
excellent comparison. same boat, same routes. very different results where it counts on the fuel economy. I have the Yamaha 8 HP two stroke because i carry it separate down to the water every time so the weight difference is still a factor for me. We will see how long i will keep it. with the price of gas and increasing emissions regulations.
Hi Paul.. yes your choice of outboard makes sense to me ..smaller two strokes are lighter. Up here E5 is now £2.03 per litre though..so thats a heafty weight for my wallet to carry :-D
Hello Danny. Would you do a video walk through of how your boat is set up please? I really enjoy your videos and had a wee inflatable myself but was a little unsure of what was really need to be safe on lo ger journeys. You seem to have battery, solar panel etc. Would be great to learn more from you. Thanks.
Well done Donny it is certainly a very big difference in many areas. I think it is at the small size of 10 - 15 hp on sibs where to have to lift your motor about that the weight advantage of the 2 strokes come into their own.
Yup ..agreed the smaller sizes suit two strokes for the set up every time guys. Many use trailers now though..even for smaller outboards ...so I feel it important they know how exxpensive two strokes are if doing any milage..however its not much more if only going out an hour or so :-D
Great review, I took went from the mercury 25hp (mariner) two stroke to this motor when it first came out. I had some initial issues being one of first owners and being at high elevation. Eventually sold it. I bought another F25 the older carbie model. It's 30lbs pounds more in weight. It is however quieter than the efi model and doesn't shake as much. They used the same bottom gear case for all 25hp so the water.pump and props all work from old.two strokes too. Service manual says timing belt at 500 hours. Otherwise time I had the motor it always started.
hi donny---good-comprehensive evaluation------i have had a 15 hp 4 stroke yamaha from new-----now 15 years old------after a few years use it started to run rough on tickover-----every 2-3 years i have the carb professionly cleaned in a sonic bath-----comes back like new------i have the same yamaha water flushing system as you but someone recently told me that when you flush with fresh water it does not go round the engine as the thermostat does not open---- not sure if this is true--------enjoy your new engine
Hi Ploughboy .. with the Yamaha 25HP EFI, the water does circulate around the engine head a. However it does not run round the waterpump so I cant run the engine as it flushes by this means. My dealer gave me this information and its also in the manual so I have no reason to disbelieve it. Once in a while I will flush in a bucker bur certainly not every time :-D
I got a ladies Jewelry ultra sonic cleaner at LIDL for £19.99 & I it cleans carb jets a treat, although it's not big enough for a complete carb. Regular boat use is the best policy as I'm sure Donny would testify !.
Hi Donny, Enjoying your video's. I have just bought a 3m inflatable. Could you please tell me what rope you carry with you for general use mooring etc. I am not sure what length or type to purchase? Thanks in anticipation.
GREAT insight I have bought and still not used my boat or my 9'9hp Orca back up engine. I am getting myself The new Suzuki DF20A it is on order and that will be my main engine. Not sure if I am talking to myself here but if you do read, Thanks for sharing love your video's. Ray K. UK. YNWA.
Hi Ray ..thanks for the many kind commets you have posted about the videos..its appreciated. I believe you were wondering about the bow covers on our boats? I dont think you can buy then as we all make them ourselves. Gordons was made from a Honwave carry bag which is why it has a Honwave logo. I believe Excel make one for their boat which may suit you ? I generally reply when I see folks posting but only when I upload a new video, otherwise I would spend half my life replying as soon as someone posts. Hope you can understand that reason. I also loose track of relies made in older videos as I dont check them after a few weeks of being on line. Thanks again for your kind comments .. and enjoy the videos :-D
Have you been getting a new longer range radio Donny ? Perhaps you can do a video on your new mods. Nice engine, I've got a 20hp Tohatsu and sometimes wish I got an electric start.
Hi Ben ..yup..got a few new goodies to go with the electrics. Im working on the video of the boat set up at present..but I get distracted by new adventure videos ..it will get done soon though :-D
Great video thanks. My Yamaha 25 efi is on a Whally 4.55. On full throttle is sounds loud to me. Any suggestions I would appreciate. My boat weighs 300 kg
Been looking at a new Suzuki 20 hp 4 stroke. Currently have a Yamaha 25hp 2006 2 stroke. Would like upgrade to the lighter suzuki, and with it being 4 stroke will be quieter and have better fuel economy. Do you know anyone that has the suzuki 20 hp 4-stroke, and their experience with them? Thanks. 👍
Hi Donny. What battery and size do you use to start the yamaha outboard. Im thinking about getting electric start fitted to my Tohatsu 20hp. Thanks Steve 👍
Hi steve..this is the one I use ..shop around and they are a lot cheaper than the link www.yuasa.co.uk/batteries/leisure-marine-garden/leisure-batteries/l26-80.html
Hi Jeff..its just the standard 9and 7 eights x 11.5 yamaha prop. I have not used a rev counter as im not giving full throttle runs yet but took a guess and bbought the 9 and 7 eigths a 12 yamaha prop for the spare.
Hi again Timothy ..its a short shaft for the Quicksilver alu hull. I was out in some turbulant seas the other day..so watch out for that video coming soon..it will let you see how the boat handles F5 conditions :-D
O though my eyes were going ploughboy so put on my glasses and saw there were still there ..but assumed it was just a computer glitch :-D thanks for commenting
Sorry you had issues with yours Brett ..im delighted with mine though. I guess even yamaha have friday afternoon outboards..hope you get your issues sorted

Another great video from a man who knows what he speaks about. Love to learn from you, Donny boy.
Thanks again SNEVIC .. Im having a ball with the new outboard ..but still learning its ways ..every day is a schoolday..even for me :-D
Thanks Donny alot of good info in the video, ive just come back from a motorbike trip in ur part of the world and thought of you as I rode alongside the water I need to get back up there with my boat
yup steven ..a boat is ideal up here ..cut you wound need the car to get it here ..so difficult choice..i loved my bikes when younger too :-D

Thanks again Ashley..hope your fog at home is clearing a bit too :-D
Brilliant comparison and you have helped me make my mind up on what to get next and some great scenery thrown in to thank you 🎣 ⛵
Thanks Alan..been doing some serious mileage lately so still delighted with my choice :-D
Fantastic video well explained!! I have just recently purchased the Yamaha motor can’t wait to try it.

Really helpful, thank you. I'm looking at a new yamaha 25 hp now.
I have bought same outboard yamaha 25hp it's great. Half throttle 18mph full throttle 23 mph. 2 up on a excel vanguard XHD435.

Great review, thanks Donny. At the end there by the bridge are you anchored for spinning or have you tied on to a mooring?
Hi Roger ..nope Im just going with the flow. Sometimes get decent size coalies under the bridge :-D
Hi Donny. What battery and size do you use to start the yamaha outboard. Im thinking about getting electric start fitted to my Tohatsu 20hp. Thanks Steve 👍
Hi steve..this is the one I use ..shop around and they are a lot cheaper than the link www.yuasa.co.uk/batteries/leisure-marine-garden/leisure-batteries/l26-80.html
Nice comparison Donny what prop are you running on the yam
Hi Jeff..its just the standard 9and 7 eights x 11.5 yamaha prop. I have not used a rev counter as im not giving full throttle runs yet but took a guess and bbought the 9 and 7 eigths a 12 yamaha prop for the spare.
I ran my 10 x 11 on the last trip 18 knots at 5800rpm WOT for info you’ll get a lot more out of yours with the Ali hull👍
Excellent video
thanks charbin ..glad you enjoyed it..and thanks for commenting
Is your yamaha a long or short shaft? As I mite buy same boat as you. My Yamaha is a short.
Hi again Timothy ..its a short shaft for the Quicksilver alu hull. I was out in some turbulant seas the other day..so watch out for that video coming soon..it will let you see how the boat handles F5 conditions :-D

Good video
Thanks Kevin ..glad you enjoyed it :-D

O though my eyes were going ploughboy so put on my glasses and saw there were still there ..but assumed it was just a computer glitch :-D thanks for commenting
Yamaha F25 is junk. I have one with 700 hrs that Yamaha techs say that's a lot of hours. I say it's a waste of money!
Sorry you had issues with yours Brett ..im delighted with mine though. I guess even yamaha have friday afternoon outboards..hope you get your issues sorted
No brand loyalty..
yup..thats true Rick .. my ex taught me that loyalty doesnt pay :-D Thanks for stopping by
