RTV Cause Cavitation? - Thrust Vectors bolt\spring - Yamaha AR210

[Doug_DeVore]

Hi All -
I've been lurking for a bit, but feel like I should post this.

Long story short. I bought a used AR210 that had sustained damaged to the starboard jet drive (guy sucked up the anchor) and it would cavitate all the time until on plane. I checked and doubled checked for debris but no luck. I finally took the jet pump apart today and found NOTHING! Wear ring and impeller looked great. I started to put it back together and noticed lots of RTV. I spent the next three hours scraping RTV off all the mating surfaces and put it back together. Dropped the boat in the river and it WORKED GREAT!

But then I dropped a bolt out of the fin thingy! Anyone know where I can get that bolt and spring before 4th of july?

Yes, give Will and his team a shout out.

Apologies for my ignorance, what’s RTV short for?

I had no idea what it means either. Found this glossary on West Marine. RTV stands for room temperature vulcanizing. Basically silicone caulking I think. Was there a lot of it @Doug_DeVore?

Permatex silicone caulking/gasket sealer is often referred to as RTV in the automotive world since there are now many makers. The full name is Permatex (insert color/temp/sensor safe/number here like Blue) RTV Silicone Sealant.

It’s like using the name Loctite as the generic for some form of liquid thread locker, even though Loctite is a name brand, again with different temps/hardness.

Yes. Permatex silicone between all the mating surfaces. I would have never guessed in a million years that would have been a problem. Obviously the guy who did the work was more of a fiberglass guy than a jet boat guy.

Boat is running great. I just gotta get that spring assembly.
