Old thread - but I wanted to circle back regarding the prop conversation to learn more about Pitch & Size and Aluminum vs Stainless, to help me better understand the pros and cons.

Here are props I have my eyes on (all 3 blade):

- Stainless Yamaha Performance Series 13-1/4" x 14"

- Stainless Stiletto Advantage 13.25 x 15"

- Stainless Stiletto Advantage 13.25" x 13"

- Currently, running Yamaha 3 blade aluminum 13 5/8 x 14"

I am overall happy with my current aluminum prop I am running. A bigger prop than the SS examples above and at WOT I can achieve the 6300 rev limit.

I'm curious what perf and speed advantages I may have with a stainless prop and if it is worth it.

The F70 is on a 1989 Montauk. 22 Gallon tank that is usually half filled. Batt in the console. No water skiing, towing, etc. Light load most of the time. 1 or 2 people with minimal gear, mostly a couple of fly rods.

As a side note, I still have the 16 Nauset (hence the thread titile), but it is still a project... and needless to say the F70 never made it on that hull and ended up on the Montauk.

I would appreciate your thoughts

Tom/Tim/Gary - thank you and others for all the prop advice through the years in this thread and other threads.

Thinking on boating in January

All the Best,
Rufus
