What prop / 2120 w/Yamaha F150

[parkerpaul]

I have a 2120 w/F150. Prop that came with it is a S/S or polished steel 14 1/4 x 16 (stamped on hub) doesn't indicate which is diameter, which is pitch. Can only get 5400 rpm wot with it. I've been using an aluminum prop 15d x 14 1/4p that seems to work well. I get 5800 rpm wot and it responds much quicker. Stays on plane at lower rpm than the original prop. At 4000 rpm I cruise at 22-24 mph. Top speed 28-30 mph.
I know there are a lot of variables to consider but I live in Baja California and going to the states to try different props is not going to happen. I generally fish 2-3 persons, tackle, 50# ice, 45 gallon bait tank full and tackle.
Does anyone have a reccomendation for a s/s or polished steel prop that would produce results similar to the aluminum prop I'm using? Thanks for your help.

You can do a search on the topic, yamaha makes a stainless reliance 14.25 x 15 prop for the F-150 that I have been using on my 2120.

my mistake , the prop is a 14.5 x 15 not a 14.25 x 15 on my f-150 powered 2120.

I have a used (2 seasons) prop for sale 15m-14 1/2, $200, and I will toss in the original m16 as well, pick up on Long Island NY, pre-powering my 2120. Sold the f150 with a prop

what was the top rpm of the props you replaced. Are they still for sale? I am on Long Island in Oakdale. The reliance prop 14 1/2 X 15 should give you 6000 rpm.I believe Parker is now using that prop on the 2120SC 150hp

My 2008 2120 with same year f150 topped out at 5400 loaded with fuel and gear, yes I still have them the other one was lucky to hit 5000, but I do run the boat heavier then most so 1/2 tank of fuel and less load I am sure you could get it 5600 if not more
