Hello WCV20 friends! Got a QQ...

I've been doing a lot of spring prep work on the V21 and 150 Yamaha. My question is about the sacrificial anodes. The trim tab anode is rather pitted - although I think it would still be ok for a bit more service. However when I pulled the trim tab bolt to drop the lower (replaced impeller) I noticed some thread damage on the bolt. It took some force to get it out and I think that is what damaged the threads.

Anyway, I might as well go ahead and purchase replacement anodes - trim tab and the one that bolts to the motor mount. Wondering if somebody can suggest the best and/or cheapest (yes I'm tight) replacements. Also if I order online I want to make sure I get the right parts. Motor is a 2004 Yamaha 150 txrc - 2 stroke.

From what I gather I probably need to hit it with some blue loc-tite to make sure it doesn't fall out. Any info from the motor heads on this is appreciated!

boats.net is where I am ordering all of my OEM parts at anymore. You can't beat tehre prices, and they're all OEM parts. As to which brand, OEM's have made it 11 years, why not stick with them. For the threads, you may need to heli-coil it, and put a new bolt in. I don't use any lctite, but a good coating of anti seize on all of them. Make sure they are good and tight, and call her a day. I have seen guys use black permatex aviation sealant on the threads to actt as a loctite coating, but it prevents salt intrusion to help get teh bolts out easier later on.
 
like ferm says,go oem parts.

as far as loktite, locking isn't the issue, unlocking is. i always put a dollop of mercury 2-4-C on them to make sure they come out later
 
simyamaha.com for Yamaha parts. For alternatives, search for camp zincs, they make the majority of zincs for us manufactures (OEM for Mercury). Make sure you get the correct zinc. Some Yamaha zincs have a little scoop on the leading edge that draws water in, feeds it back thru the exhaust housing and helps cool the exhaust. It will burn out a prop hub if you don't have it. If you have the lower unit dropped, you'll see the tube that runs from the trim tab cavity back to the exhaust outlet(not all yamahas have this). Get the oem bolt, its a special bolt(smaller head so your socket will fit thru the hole)
 
Great info guys...exactly the input I needed. If I get a break from work tomorrow I'll do a little research and maybe post up what I find before I buy it....to be sure.

BTW, got the impeller in and lower back on. That shaft collar (seats right above impeller) was a b*TCH to get off. Not too bad going back on.

those collars can be a pain, I've got a couple tricks but sometimes I just have to cut them off and be done with it. I keep saying I'm going to build a tool to pull them off, but never do
 
Yea something like a giant gear puller would be the ticket lol. I almost hired it out without even pulling the lower. That is what I did last time but that time had to get the fuel pumps rebuilt too - not something I wanted to tackle at the time.

Spare I'm curious to know your input on fuel pumps. Maintenance item? Or don't fix it if it ain't broke? There seems to be two schools of thought on that. With todays gas I'm leaning rebuild em after a set number of hours or years, whichever comes first. One of my crapped the bed after only 5 years.....on factory brand new motor.
 
Yo Bradford! Yea, I agree. Miss all of you guys!!!! I got laid off from my pie job (after 16 years) last July. Started a new one in August and working my tail off ever since.

I just don't have the time like I used to have. I'm not complaining tho. I got one girl heading off to NC State in the fall and the other will be going to school somewhere in 3 years!

I'll try to do better..... :party:

I don't rebuild Yamaha fuel pumps, I replace them. The kit cost me somewhere around $25, the whole pump is around $42. Not worth the time to fiddle with those thin gaskets. I do put a socket/screwdriver on the fuel pumps at every service, they tend to loosen
