Member Posts: 39 Comments: 0 Joined: 06/15/10	Hello Can someone please give me some advice on purchasing a new stainless steel propeller? I have a 1989 Montauk with a 1988 Yamaha 90 HP. I will be using it the NJ Bays and Ocean coastline. Can someone also recommend a place to purchase? Thank you for your help. Edited by Tom W Clark on 05/23/13 - 9:14 PM

It is an excellent value. Shop it down online; you will find it is less expensive than a lot of other propellers that are not as good.

Member Posts: 39 Comments: 0 Joined: 06/15/10	Just purchased the Stiletto 4.25 13 1/4 X 15 - RH for my 1988 90 Hp Yamaha. The prop looks great but it is hitting my Trim Anode.. I tried bending it some but it still hits. Can some one advise me of a replacement or can I just grind some away.. Thanks for responding...

I am a bit perplexed, you purchased a 13-1/4 x 15 Stilletto and it does not clear the trim anode? For my 2007 Yamaha 90 I have to different stainless props, one is a 13-1/4 x 17 the other 13 x 17 and I do not have a clearance issue. Check this web site for a reference to the proper trim anode versus the model you currently have installed (part numbers that is). www.simyamaha.com Good luck... 1996 Dauntless 15, Sportsman Pkg. - 2007 Yamaha 90 HP 2-Stroke

Or did you accidentally double stack the new spacer (if supplied with new prop) ahead of the old one? The prop spacer is roughly between 1/4" to 5/16" inch in thickness and splined at it's center to match the output shaft. It rests against the visible bearing face of the carrier housing. 1996 Dauntless 15, Sportsman Pkg. - 2007 Yamaha 90 HP 2-Stroke

It can be seen on page 7-13 (166) of the Yamaha Outboard Rigging Parts Catalog: http://www.yamahaoutboards.com/Marine...s_Catalog/

I jumped the gun an ordered a Flat anode (Shorter Dimension ) but I do want to get the correct one also. Tom /Dauntless Thanks very much for your research. I cant wait to try this new prop out. Hopefully the shorter one will not effect performance until i get the one Tom noted.

I am still a bit stumped (and I bet Tom is too) on why the prop does not clear the trim anode? Was it the hub kit that was installed in the new prop?

(My father in Law said he was staying 3 days over the memorial day weekend. he left on Saturday??) I just wanted to thank everyone for there help. Tom Clark's advice on going with this prop was a winner. It matches up so well with the boat and motor. It came up on plane very fast I did not check it at WOT but will report back.
