Re: F150 Temperature sender location

to clean the water passage anodes remove the 12mm bolt, pull the assy from the passage, place the holder in a vice,gently, and unthread the anode. you may have to hold the 10mm bolthead. if you try to unthread the 10mm boltheat odds are it will snap off. if the anode is still intact, and most are, dont remove it from the holder just clean it till its shiney again with sand paper. 60 grit works well. do not use a wire brush or any carbide papers due to the metal transfer to the anode.carefuly inspect or replace the holder oring and reassemble it.

Thanks rodbolt, I'll have a go next week... the weather's looking way too good to do maintenance this weekend. How bad could the anodes be on a one-year-old 200hr motor that gets flushed for a few minutes after each use (virtually every weekend)?

im sure you could find a murphy guage to suit the sender range and wire it to kill the engine. a lot of diesel installations use them for just that purpose. keep the guage tool handy incase you are at a point where you dont want to stop so you can reset the kill point. or just set it to trip an earlier alarm.<br /> http://www.cornermotorsales.com/versus.html

hello<br /> in my opinion the anodes are like teats on a boar hog. they usually create more problems then they solve.<br /> the problem is after a few wet and dry cycles they calcify. without proper cleaning they get a hard white coating and quit working. any anode that has that coating becomes just another piece of metal along for the ride.

Are these cylinder head anodes added because the the block or cylinder head is aluminium?<br />Are you saying that the coating can flake off in the cylinder head?<br /><br />I never had them on my cast Iron car motor based I/O's except on the aluminium Outdrive.<br />I never did maintenance on those until they were almost gone and then replaced them.<br /><br />Last I/O boat went 13 years that way and I got rid of it only because I lost faith in it's dependablility (bad starters and that sort of thing)<br /><br />I only replaced it because I lost faith in it's reliability because stuff was starting to break like starters/alternators/

Re: F150 Temperature sender location

Rodbolt,<br />Just a quick note of thanks... after a weekend on the water, last night I took your advice about zincs. I found one zinc in the block and four in the cylinder head of the FT60. I removed and cleaned all of them. The block zinc was in good shape but the head zincs were all covered in light brown calcified material and took a fair bit of cleaning. You've undoubtedly saved me from a corrosion problem, but my main question has to be of Yamaha. Why don't they mention doing this in the manual?

Re: F150 Temperature sender location

i believe its mentioned in "dot form" in the service section. yamaha manuals are not meant for untrained boat owners, unfortunately some "deciphering" is required at times.

Re: F150 Temperature sender location

Just had a brainwave thanks to BenC. Maybe where the dot form maintenance page mentions anodes, they include the "zincs" which as rodbolt points out are the anode holders. Pretty obvious once you get the picture, but, the owner's manual isn't good at helping me get the picture... anyway, I know now and will be cleaning up all anodes at regular intervals. I've another question which may well already have been answered but can't find anywhere on the forum... if you use flush muffs do you need to also flush using the screw on connector hose on the right hand side of the motor?

Re: F150 Temperature sender location

depends on your hose pressure. sometimes i have to have the muffs on the gearbox and another hose in the flush, usually only on the v6's. attach the water and turn on the tap. start the engine and if the telltale doest show within a few seconds, 10 or so? try another hose on the flush.

Re: F150 Temperature sender location

Thanks BenC. I get a tell tale virtually straight away... I live half way down a hill and get great hose pressure! Even so, I'll use two hoses for a while and see how the zincs look after a couple of months.

Well, no one answered so I just went ahead and tried it. <br />It works and I now have temp and PSI gauges.<br /><br />The insructions for each of the 2 gauges says you can only use one but I guess tta doesnot apply to the F150

Re: F150 Temperature sender location

Redstone,<br /><br />can you confirm? You installed water pressure adapte r in upper (#2) M14 plug hole in port cylinder, and water temp sender in lower (#3) M14 plug hole in port cylinder in port cylinder of F150?<br /><br />I found the #1 to not carry water. Yamaha tech in Port O'Conner said that was the right spot for pressure. I used the T fitting in the pilot hose but I'm not convinced this is the best install.<br /><br />What water pressure are you getting at low, mid, and high RPM?<br /><br />Thanks
