Yamaha 150 txr and saltwater

[Deleted]

Heloo and thanks in advance for any answers to my question. I have recently purchase a 2005 190cc with a 2005 Yamaha 150 txr. We will be going to Edisto Island in SC in a few weeks and I'm not sure if this motor is saltwater ready. It is my understanding that you should have anodes on the motor? Any information would be greatly appreciated!

You do need a sacrificial anode.. zinc is the most common.....but you should use one in freshwater too... because any time you have two or more different metals (such as an aluminum prop and a steel prop shaft) moving though water, the metals create electrical current which is VERY corrosive...a sacrificial anode attracts the current and eliminates the corrosion on vital engine parts...

That being said, one or two short trips in saltwater probably won't cause any noticable damage....but why chance it? Anodes are cheap and expendable....engine parts aren't.

Wouldn't the Yahama already have these in place? I have never seen a major brand of outboards not have them unless it was a racing engine.

tsprattiv, p-jimmy is right, you are fine as far as anodes are concerned. If you ever have any questions about what is what on your motor, I've found this link to be really useful: www.yamaha-motor.com/partviewer/default.aspx?ls=outboard . There are other good sites out there but that one has worked well for me. There may be a difference in the abundance or quality of the stainless steel on a saltwater series motor to others, but I don't think you will have any trouble at all, especially for such a short time. Rinse and clean everything real well after you get back.

Thanks for the advice. The motor has a ss prop and the owners manual diagram of the motor shows two anodes but not the typical zinc plates I've seen on motors in the past.

Good deal. Any sacrificial metal should do the trick. There is likely one on your mounting bracket as well. Juan explained it well...they're inexpensive and a must. There's no better way to enjoy the coast than in a boat. Have a good trip and be safe in the unfamiliar waters.

I bought a 150 in '02 and other than the decals I couldn't see a lot of difference between the freshwater and the saltwater models except the price. 10 years in salt so far (knock wood) no problems.

A reliable mechanic who works on them all the time told me they were the same - just decals, and all of the SW series have a 25" shaft.

My ProV and the newer VMax engines have 20" shafts - targeted more to flats and bass boats, while the longer 25" shaft Saltwater series is targeted to bigger saltwater boats.
