Re-Pitching a Stainless Prop

[John Jones]

I used General Prop. twice on rebuilds.  They were fair to me.

General.  Why was I thinking Hill?  

[Circle Hooked]

Yep General, just down from Tropicana, done alot for me in the past, good folks.

Kinda made me cringe once when I was by there.  I heard this loud clanging from the shop.  Dude was making full power swings with a sledgehammer on a propeller but it was probably a 30" diameter prop.  I assumed he knew what he was doing.

Also known as a "precision adjustment device"...

Ahhhh... The BFH. or RBFH, yes, I have several to choose from   WARNING: Use of this tool will result in fixing the problem, or generating a larger one.

Or you can sell the prop to me and buy a new one!

How is that prop working out for you?

It's stowed under a forward bunk as a spare. I need a 13x15" to get me in the proper RPM. Not to mention the hole shot improvement.

Let me know if you are interested. Not too many Tohatsus out there.

I thought you were kidding, since you bought my last prop.  I'll let you know what I decide to do.

our mechanics in the marina use General

wing, I bought my prop from Admiral, gave me a super deal since they had this one in stock for awhile. I'll give them a call.

Blue Agave I've already raised the motor, twice, and went from a 13.25x17" prop to a 13.25"x15.  By raising the motor and switching props I went from 4200 @ WOT to currently 5000-5100rmps @ WOT.

Im happy with the overall performance/hole shot etc. I just want to bring my WOT RPMs up a bit and if its possible/advisable to change the pitch from 15" to 14" in hopes to gain 1-200 RPMs im all for it.

Hi, I was wondering about where the motors cavitation plate lines up with the bottom of the transom since raising it? I have a 90 Tohatsu/Nissan on my 175 and I have it set in the lowest mounting position which puts the plate just about even with the bottom of the transom and am thinking maybe I have it set too low....

Thanks,
Roger

Roger the cavitation plate should be about one half inch to one inch above the bottom of the boat. Next time you are out while the boat is up to speed have someone drive as you look, the water should be in contact with the bottom of the cavitation plate.

Called General Propeller, and let me tell you the rep Kevin was super helpful and very informative. Told him what was going on, and what I wanted/need to achieve.(even said hes looking for a classic 19-6)  He suggested trying an 13.75x15" aluminum prop first. Same pitch, larger diameter than my current prop. Then, if im not happy try a stainless 13.375x14".  He said I could try out both props, and as long is there not damaged, swap it out for what ever I decide.

I was kinda shocked when he mentioned an aluminum prop first, as most prop places scoff at the idea (Which I never understood why) Usually when you mention going form Stainless to Aluminum, they say "You can do what ever you want" or something smart Arss to that effect.

[Blue Agave]

IMHO stainless is the only way to go.  Aluminum props are not practical for shallow water application.
