Stainless Steel Prop Question...

I bought my boat used and it came with an aluminum prop. I done bent it up pretty bad. Some dang structure off the north Fannin Landing got me last year. Anyway, I want to start looking at stainless steel prop for my boat. The only marks on my current prop says 21K so I assume the pitch is 21. I need to measure it to see the diameter..

So... reading up on props I see that the pitch needs to be right for the boat and weight of the boat. I have heard to go down one inch in pitch for SS but don't know if that holds true. Any info on this?

I guess I could just get my prop fixed or buy a new one for about $70. The SS seem expensive. Yall got any info on where a man can get a used SS prop or a good deal?

My motor is a 2007 Yamaha four stroke 90 HP (F90) and my boat is a 1860 G3 with a good bit of weight due to the 2 - 82 lb Trojans in the back... plus one interstate 24.

Thanks,

I like stainless steel props....they are worth every penny. I always replace the aluminum one with the same size and pitch in stainless .....thats been recomended to me by three boat dealers now. Never has exceeded the max recc. RPMS

STAINLESS........... accept no other! :) Keep an old aluminum one for a spare. We tried out a couple of used ones to get the right pitch for our boat and then ordered new. :)

General rule of thumb on big motors is SS will let you step up in pitch by 1". This may not hold true for mid sized motors - dunno. The 21 you've got can't be measured with a ruler, the 21" desribes the rake or cork screw in the prop and can only be accuratly measured by a prop block. All else being equal, a SS prop is more efficient due to less flex in the blade translating to less slip and more power being put down. You should also see a quicker hole shot.

As far as which prop to go with - go by a good prop shop...one that specializes in outboard props. Most of any size will let you try before you buy. As G said, never under prop a boat and over rev your motor. Not sure on your motor, but most Yammie 4 Strokes want to be propped at 5500 which is mid point of the recommended range. There's the sweet spot. It sorta like having a 363 Stroker with a 1 speed transmission. You've got to find what works best for the largest range of how you want to run. Prop for top end, and hole shot stinks. Prop for hole shot or load carrying and top end stinks. Prop for handling in turns and one or the other or both stink. Shoot for the middle in most situations.

The Prop Shop in Jackson will let you try before you buy, but given the quantity of boats similarly rigged to yours, a high volume G-3 dealer could prolly tell you without thinking which prop would be a good one for your rig.

Stainless for sure Zack. There's a prop shop in Pearl that has some used ones and Art's place in Ridgeland.

I run a 21 on an 1860 with a 115.

I also run a 21 on a 115 two stroke. 21 seems a little high fer a 90.

It does don't it Minner. But the G3 is a light boat, so I didn't mention it.

I run a 23P SS on my 150. Go by C&S on Lakeland and see if they have a 20P. They are open and selling everything.

Exactly....they know which one you need.

Theres one in the classifieds for sale.

Yamaha......which owns G3....reccomended a 13.25X21 on my four stroke 115 Yamaha on my G3 Eagle 185....It worked great.

Making my head hurt with all these disissions.

Got to help stimulate the economy.

I am doing my part.....been watching Major for about a year or better now.....been learning from the best you might say.....I think I have caught on and I am going to do my part to stimulate the economy just like he did. Rofl

G? Who are we gonna leave all our stuff to when we go? Don't think my granddaughter or grandson will want mine.

Check with David at the Prop Shop right off Flowood Dr and the corner of Old Brandon Rd. I traded in a SS prop that he said would work on yours, if he still has it. And if he does, he will tune it until you are sastisfied with MPH/RPM.... He did mine...

Yep, got mine from David too and he will fine tune it for you.

Thanks for all the info. I appreciate it. I called Art yesterday. That guy knows his stuff. He said to stick with a 21 if it has worked for me in the past. He could fix my aluminum one for $70-$100 or order me one for around $350. I am going to call around and see if I can find a used one. All else fails I found a brand new aluminum one for $70 that is the exact same as the one I got on my boat. I still want to get a SS prop though.... I will call David and check with him...

$350 for an aluminum prop? I'm glad you shopped around.

No no no... I should have been clear. A new SS prop for $350. He could fix my aluminum one for $70 to $100. I also found an aluminum one just like mine online for $70 brand new. The aluminum ones are pretty cheap.

Thats not a bad price for a new stainless that size.

Yep, but you can find them used for 150 to 250 pretty easy once you figure out which one you want.

That's like tellin him not to breathe G... Aint gonna happen...

Maybe he's just being "thrifty" not cheap... This time anyways

Your right Mo, lmao

Yeah and seems like his thriftiness has paid off! He's shoppin' furniture and boats. :)

I told you where to go. C&S Marine!!

Called C&S Marine.. They said they had about 50-60 props but were all Mercury props and most were 23 - 25 pitch. Said the mercury prop would fit with a different hub. Might holla back at them later on. Tried to call David a Prop Shop in Flowood but he was out. Should be back later this evening and I will see what he has...

Thanks,

DoubleG

David at the Prop Shop is the way to go. I wouldn't get one from C&S if they were the only ones around.
