- This video is a little different from normal, however several subscribers have asked if I could show the outboards in more detail and as I was doing a full service on the Mariner 25HP which includes water pump, thermostat, carburettor rebuild, etc before winterizing it, I took the opportunity to video my task.. its for interest only and not a technical guide how to do it as Im not qualified for that. Enjoy it and perhaps you may find it useful.
There's no end to your talents Donny and with a good service well done. Really enjoyed watching. Atb Steve 👍
This was a wonderful video and very detailed. A job well done. Thanks for taking the time to document your work.
Thanks Doug ..glad you enjoyed it..more videos are coming soon so stay tuned
Thanks for posting Donny. Reminded me I'll need to get my Tohatsu ready for the winter.
Thanks DiveRIBOrca..yup..best get the service done so its ready for the good weather..it can return at anytime ..hopefully :-D
Very informative clip. Thanks Donny for sharing.
Fantastic video, just purchased an Orkney strikeliner with this engine, recently serviced but for peace of mind I will fully service with new impeller. Thanks again
Well done Donny, i really enjoy it .
Thanks S Cho..hopefully plenty more to come :-D
thanks Donny Im in canada and have a 2 stroke 25 hp 1986 mercury pretty well the same as yours it was a pull start but I managed to turn it into an electric start by scourcing the parts works good but is tempermental when comes to starting so I will have to do some carburetor work as Im sure thats the reason, you video is the best out there explaining everything hope you have a more detailed video on the carburetor serviceing thanks again
Super material thanks:)
Thanks Ar ..Im delighted you enjoyed it ..the lastest is now uploaded so hope you watch it too :-D
Hi Donny, i found this very interesting as i noticed the last time i was out my Yamaha didn't seem to be pumping a lot of water, i will order the parts and give it a go cheers Harry.
Hi Harry.. hopefully the video shows its not to hard assuming you put everthing back the way it came out..thanks again for stopping by :-D
Wonderful!
Thanks Brian.. I have the OB dewinterised now and a few trips under its belt and its going sweet as a nut :-D
Good Video thanks
Thanks Andy .. the outboard is still going well..so I must have serviced it correctly :-D
hi donny -----i do most of my own servicing--------15 hp yamaha 4 stroke ----but don t trust myself to do carburettor------every 3 years i send the outboard off to have the carb cleaned in a sonic bath------rran like new when it came back this year---but only managed to use it once
Thanks ploughboy.. good idea getting the carb done in a sonic bath. I started in 1975 stripping the carb on my first motorbike.. so have done in many times since. Although Im not a great lover of 2 strokes..they are easy for me.. I would be lost with EFI technology now
Fantastic video Donny. Must service mine now 👍
Yup.. keep them serviced and reliable Boatsbitsandbobs ..then they wont let you down at the worst moment . I dont worry about mine when Im out a sea..but still carry a small Aux
Hey just wanted to let you know that your gear box needs new seals because the oil is a milky colour which means there is water in it.
Hi Donny, great video!
I have a 1997 25hp mariner 2 stroke and need to reassemble my tilt lock and shallow drive. Finding info online or even photos is difficult.
Next time you have your engine out do you think you could send me some close up photos of the mechanisms? Particularly where the springs seat on both sides???Thanks! 🙂
Hi Thomas ..I hope you have found the info you required..if not ask again and I will get some photos for next week
you forgot to molly-lube the driveshaft splines! but other than that perfect job! PS you can use regular dish soap for the impeller. i used to use marine grease, and switching to soap has made it so much easier to install impellers it being that much more slippery and all. cheers from the USA!
You actually want to use lubriplate which is designed for water pump impeller lubrication. This lubriplate grease NEVER washes away with water and will stay there forever to always provide lubrication for the impeller, especially on that first start up.
I meant to say Triple Guard. Not lubriplate. Evinrude makes the Triple Guard grease. It is truly designed for water and definitely should be used instead of trailer grease
@@galaxys7650 you can use triple guard, but if you get some in the relief hole it will cause issues.
What pitch prop were you running? I have a 11” and thinking of going to a 13”
Awesome video! Just got one and the first time removing the prop… stripped the nut😐
Aww..Sorry to hear that James..its easy done though and I never understood why it didnt have a locking nut ..hope you got a new nut easy enough
@@donnywilcox thanks! How tight do you do it up? Never had a plastic nut on any prop I’ve had before!!
@@jamesrichards5998 Hi again ..I just screw the nut up until there is no slop if I try to pull the prop back and forward.. then possibly 1/4 turn onto that. It does seem a bit strange..but remember when underway the prop is forcing itself on..not off..and the prop splines stop it from spinning.. so it doesnt need much torque or it just strips. I do the same kind of torque as my spark plugs..hope all that makes sence. I have done many thousands of miles with the one plastic prop nut and no issues whatsoever as long as I dont overtighten and strip the thread
@@donnywilcox awesome thanks! Looks a great engine! Mines ex MOD and only done 26 hours from new so can’t wait to try it out!
Is this model the Mercury/American model?
Thank you!
Very nice Donny. I live near the Great Lakes in Michigan and we have crystal clear fresh water running through the cooling system. My 1997 Mariner 25 runs like new to this day and I have owned it for nearly 24 years. The trick in the US is using the right gasoline. The alcohol blends will destroy an outboard, so we buy "rec gas" for $1.20 more than the expensive Biden Blend that is full of alcohol and they run perfectly.
Thanks Brian ..yup in the UK we are getting 10 per cent ethanol in the fuel come autumn. Means I will have to spend more to get the better stuff too.. its life I guess..any way for them to make more money and we have to pay :-o
Hey. Is there a thermostat on your engine? I have the same motor as you. Best regards
@@mattiasforsberg5389 Yes, the thermostat works quite well. These are outstanding outboards.
@@brianhalliday2384 Perfect. Is it normal that the tell tale it's a little bit Irregular because of the thermostat. Strong tell tale for about 10 sec and then a weak tell tale for about 5 sec, and then it repeats. Excepts under higher speed, then it is stronger. Or should it be a strong tell tale all the time?

What is the oil mix ratio for your mariner?
I was wondering was there something missing on my 20 mariner, to I saw this clip. Only a nylon nut holding prop on? Should I lock it up with a second nut or is this setup okey ?
Hi Corsur..I used to think the same..but no..its only the one big nyloc nut that holds it all on. I guess the prop spinning tends to tighten it ? and that is why. Most other OB s have split pins etc..but not this model of Mariner..Its done thousands of miles and never come off so I dont worry about it now:-D
Hiya donny I would really appreciate if you could tell me the size of the transom on this quicksilver would be a great help, cheers
Hi Ben..I cant remember exact measurement and I no longer have the boat. It was one of the older Quicksilvers so it was a short shaft OB. The newer Quicksilver with the rounded cones ..(instead of the older pointed cones) takes a longshaft ..or so the adverts say. Hope that helps
I just bought a mariner 25 for 4 days ago, i drived it like 2hr then he just stopped, i tryied to start it again and it's kind of dead, i'll run a service just as in the video and see if i can bring it back to live. :)
Thanks Matihasj..good luck with your repair.. check for a spark at the plugs first..if no spark..most likely an electrical fault. If spark at plugs..most likely fuel fault :-D
What water pump goes with this motor I have same motor cant find right impeller seal kit
Hi John . watch the video..the packet with the part number is shown,. I cant remember off my head which is why I mention this .. also if your OB is different year it may not be the same ..hope that helps
