Stainless Steel Teflon (SST)

[Deleted]

back in '04 when we bought our boat with its 90 hp Johnson Sea Pro outboard it came with a black prop and I remember asking asking about going to one made out of stainless steel .... I distinctly remember being told that the black prop was made of stainless that had been coated with Teflon .... I was told that it was known as a SST Prop .... Stainless Steel Teflon .... until recently I never had an reason to question what I was told but our son is using the boat, doesn't seem to believe that story, and wants to install a stainless prop .... I guess it all boils down to is if the SST prop on our boat is stainless coated with Teflon and if so, is there any advantage to replacing it with another stainless prop

It appears it is already a stainless prop...their website shows it as being black as you described, but doesn't mention what the coating is. from BRP:

SST - Stainless Steel Props: (Stainless Steel Tough)

A Stainless prop will last longer than an aluminum prop, plus offers greater performance - beneficial for avid boating and water skiing. Has a "Thru-hub" exhaust and 3-blade painted stainless steel design. A low pitch propeller that comes standard double cupped, and is also available triple cupped for pontoon applications. SST props are repairable if damaged.


The SST propeller is 5 times stronger than an ordinary aluminum prop. The blades thinner are thinner for a cleaner bite to achieve higher top end speed. The SST is a fast planing prop with thru-hub exhaust and cupped blades. More expensive than aluminum, but highly recommended for the serious boater.

If it's black, it's aluminum (unless someone painted a SS prop and I doubt the paint would stay on for long if they did)..
As freezerfiller said, a SS prop will perform better and is much stronger..... the down side to that is if you hit rocks or concrete with a stainless prop, you could do a lot of damage (drive shaft, etc) where with an aluminum prop you'll probably ruin the prop but do no damge to the motor.

Yammie painted their SS props black as well - no problem (good props actually).

Hmmmmmm, I stand corrected

thanks for confirming what I thought was the case .... as noted, our son has our boat .... when he brings it back over Labor Day I am going to check the prop .... hopefully it will be in condition where it can continue to operate well for a long time to come
