To the person that created this video, you did a wonderful job. I used your video to replace the impeller on my 1985 Mariner. Couldn't have done it without your help. I have a request for you. I took your video and added the extra detail that I needed to complete the job. I think this extra detail would help others as well. I used some of your pictures and all your ideas. I just added some pictures and expanded on your talking text. I would like to post my version but feel I need to ask your permission. I did begin my version by acknowledging most of the information came from you.

My Gear shaft is stuck in forward on the lower unit,

Hi, which is the screws to adjust and tune timing

Excellent tutorial, thanks for making this.

Thanks for this video. It inspired me to sort out the impeller on my 1996 Mariner 3.3. New impeller arrived very quickly and I set to work. The first two bolts came unscrewed beautifully. The third, just above the propeller seemed to turn quite easily but then sheered off. Now there is nothing to do except take it to a workshop which has proper screw extraction kit and a supply of screws of the right material. Clearly this screw had effectively welded through electrolytic corrosion to the aluminium casing. Now I am stuck. Until this point the motor had been amazingly reliable and in the previous two weeks of daily use it started every time first pull.

Thank you for making this video!

Brilliant thanks man

Thanks so much for taking the time for this video, very helpful. Just had to do a carb cleaning and gasket replacement and this helped me through it. These old motors will run forever with a little maintenance.

audio not audible which way do you spin the drive shaft as you slide the water pump housing down over the impeller ?

Thanks, really great explenation!!

Dolls house lol :)

Good video....thanks

what size and type of propeller does this motor have? I got ahold of one but it didnt come with a prop and I cant find the schematic for it anywhere

thanks save me a lot of experimenting and worked well, impeller shot to bits, now need a new one

thanks for this instructional video, helped a lot!

I have the 3.3 hp model. Refitting this assembly is a nightmare.

Thank you very much for posting this video,i did the job in no time,,,A plussssss

While changing the impeller, that little gear clam that's not suppose to fall off - fell off. It is shaped like a 1/4 circle (so to direct the gear rod in or out). Does anyone know which direction it goes; to send the gear rod further or closer to the shift rod???

Hi anyway you can make me one up same outboard have access to a lath for the o ring grooves ??

How can you tell what yr your motor is on these outboards i need to order parts but dont know year of mine?

is the gears the same for the Yamaha 4hp 4 stroke as it is for the mariner 4hp 2 stroke.

Brilliant! Thank you very much.

I have a Yamaha 4hp -83 that looks exactly the same. All parts are just like in this one! :D

Jack, I think the pump must be the rubber membrain. It has flaps in it so I think it must pulse when working. This engine had a tank and also provision for an external tank. Very handy

Does this outboard have a fuel pump at all? Can you use it with an external tank? Or is the fuel pump and carb all one unit? Thanks

thanks for an excellent video - followed to the letter and had great success. Once again thanks.

Thanks mate. Mine is just really stiff. The previous owner never greased it. It isn't broken only frozen. If I can't free it up, I will follow your instructions.

We just changed the impeller on our '98 Mariner 5hp. There were only 2 blades left on it! This video saved us time and money for more fishing trips! Thanks again!

Cheers

I saw some on Ebay a year ago but they all seem quite expensive

Have you any idea where i can buy seals for the carb?

not sure how to dismantle the pipe, it's a long time ago now. Try this site crowleymarine com

I also tried to fix a pipe and blow from end and hold the other end, but air seems to leaks, - regards.perhaps you can guide me. Many thanks in advance

Water is quite hot, and i thought that it was the fault of the impeller, but it seems perfect. I later fed gravity water from a bottle and saw that water also leaked from the open up lower part as shown in your illustration, you can say that 50% came from the actual exit, and the other 50 % came sliding down from the bottom cover which i had opened. Possibly as i could not see deep inside the whole housing, i suppose the pipe is leaking that leads to the impeller.

thanks dude- very educative- loved it- i have 4 hp 2 stroke yamaha outboard and did exactly the way u dictated. But sorry to say, that the impeller was perfect, but the water pipe that follows the impeller towards seems leaking. Could you guide as to how do i remove that water pipe for replacement? For information, you see, i have a very poor pee from the exit.PLS SEE NEXT POST

all you efforts to assist me will be appreciated.

Thanks for this.Now I can get my '89 5hp Yamaha running again. It has been standing 3 years and did not want to run this summer.

Thank you sir!!!! You have saved us a lot of time and hassle!! We were puzzling over where the impellor was for ages and then we luckily found your video. Thank you thank you thank you!

Remove the 2 bolts and tap a screwdriver in the joint. Do it carefully from both sides.

does anyone know how to remove the piece behind the propeller at 1:16 to get access to the gearbox.I removed the propeller and took out both bolts but it dosent seem to be coming out.plz respond

How about changing the Thermstrat on this motor? I think it on top left side. Any video on it? thanks

i watched youre video after i changed the impeller , you done it right to hahaha

Excellent video. I am hoping to replace the impeller in a 5 hp Suzuki I have, and I suspect it's design will be very similar to the Mariner in this video

If the shaft is still in place in the engine it must be stuck in the splines somehow. Try clamping the shaft with molegrips and tapping them downwards with a hammer. Good luck Mick

This video was great. i got 1 my own, i got it free from a friend and the water pump was not working. and i'm new in boat motors, But hx to this guy, he made my day:D btw, it was my impeller that was destroyed

Thank you for your help. I have now replaced the impeller on my Mariner 4HP I got informasjonnen I needed from your video Greeting from Haugesund Norway Tore

gee I hope it works on my 2000 merc 3.3. Shouldn't be much different.

@jacksonfearns If it is a flat plate with 2 grooves in it, and a hole in the middle of the grooves, then it is a two piece bit. Maybe the other half has fallen inside? I can only see a 1 piece plate working if it has holes for the rods to go into, and there is some sort of split in the holes that closes up when you tighten the bolt, but I'm only guessing Regards Mick

great video. having slight difficulties re assembling my outboard. I have the slightly later version off this outboard and the clamp for the gear shift rod came completely off. also is it a two part clamp because mine only appears to be one half?!?! thanks

No, you don't have to drain the oil from the gearbox. The impellor unit comes off with the gearbox. If your engine's overheating check the main waterways. I can't remember but I think it runs up the tube from the impellor, round the block and back down the central leg.
