Perfect no nonsense video, thanks
I only bought an f70 a few days ago here in Australia. three month wait before I get it and I won't be doing this process for a good amount of time however this video is great to show where things are / how to do things.
Very nice video. I NEED one of those ratchets! 😉
Hey, thanks for the nice video and easy instructions. I just repowered my 16 foot Islander with a 70HP Yamaha last year and I only fish saltwater and go in skinny water. So changing out the thermostat is a must. Hell, the sand alone used to clog up my 60HP Mercury. Thermostats are cheap--engine blocks are expensive. Also, nice view of a what appears to be a great looking shallow water boat.
Salut, super ta vidéo👍
Pourrais-tu faire une vidéo sur le changement des anodes internes ainsi que du filtre à essence ? Merci
The torque spec is a two stage to seat that gasket. 4.4 lbs.-ft. for first stage and 8.2 lbs.-ft. for the second stage. New bolts are not required as per the service manual. No need to grease them...that skews the torque. However, the bolt threads and mating threads need to be cleaned before using the torque spec. You may think it is not leaking by "snug" tightening. However, you are not observing operation at wide open throttle. I would check the area after usage a couple times. This "greasing" of bolts is a widely used DIY tactic that is not intended for a dry torque spec.
Thx for the comment this is much appreciated.
Great info, especially as far as bolt torque goes. I have 2007 yamaha f50tlr 4 stroke and would like to ask if those part #'s would on my outboard? Would appreciate it if you could help me out with this. Thanks, Steve
Thanks for taking the time to post this video and the100 hr tune-up video from a couple years back on your F70.
You mentioned being able to 'back-flush' the motor with the thermostat removed . . . could you explain a bit further?
Also, you mentioned somewhere that You use a bucket to flush the motor as it doesn't get a thorough flush using a flushing attachment, are you still using that technique?
I have the same motor on a 1988 15 Whaler and have 450 flawless hours on it, great set-up ! I just ordered the internal anodes for mine since I run 90% of the time in saltwater.
Thanks again for posting these videos, really good info.
so the back flushing is if you had sucked up sand into the engine and you need to wash it out. So I also use my boat in southern Florida saltwater 99% of the time and yes i use a horse trough that i bought from a tractor store run and flush my engine.
@@ShallowHookerFishingbasically what we are asking since we are scared to do it. You mean we are good to put a hose in there and blast it water😂?
Im curious to see the condition of my thermostat, if i open it up can i reuse the same gasket?
I would not if possible
can do a timing belt replacement video?
I’m not there yet on my engine but I will when it’s time they are really easy to do with the correct cam holding tools
@@ShallowHookerFishingpardon me if I missed out any info in your videos, how old is your engine?
