I just acquired a 2005 Yamaha 4hp 4 stroke and found this very helpful. Your directions are very clear. Thanks

[@ironix1]

Entirely helpful video on a very popular outboard. Thanks

[@jaydut]

Thanks for this video mate. Really helped me out. Managed to do my 5hp short shift because of you 😊

[@bala5436]

Excellent video man! I have the same engine so this will come in handy. Thank you.

The rubber hose in front of the drive shaft isn't the exhaust, it's the water feed up to the motor from the impeller!

[@mickwinnett8308]

surely the key slot in the impellor dictates what direction it will be going.

[@danielpyrig8321]

Sam I think I got oil leaking from the Shaft, do you think I broke one of the seals up top? Is it easy to break

[@limebulls]

How often should a impeller be changed?

[@gogan3429]

Good question.
Is the answer when the water isnt coming out the pee hole?

[@timfallagain7808]

@@gogan3429 my Yamaha F4B manual says 100 hours or yearly whichever comes first.

Very clear video on doing the pump If you find the pee hole is still is still giving you warm to hot water I found the best way to clear the pee hole was to drop the bottom leg
put a fuel line in to the brass water pick up connect the fuel line to a
garden hose using a clamp and force water up in to the gallery's and
out the pee hole using the bottom leg with the normal water pump
impeller does not create enough pressure to clear any trash from the
power head (impeller was in good condition)

Very well explained. Thanks a million

That was as close to perfect as possible. Great video. Thanks.

Hi Sam, do you know where to a shop manual for the F6S engine? Nice video bye the way

[@gogan3429]

How do you know when the impeller should be changed?
Would it be when the pee isnt coming out?

[@vespa1239]

Great instructions. One of the best I've seen so far. Thank you very much.

[@MrAJM728]

Thank you for the tutorial. I have the same motor.

[@robferenczi3024]

Good video but what about the impeller gasket?

[@kCI251]

Wife would kill me for taking apart a boat motor on her carpet.
