ever had a prop re-pitched?

I've got a 62 16 foot hull with a Johnson 90. My motor turns about 58-5900 at full throttle, redline is 5500. I had thought that it would be just right when I added some more weight, but that hasn't really made much of a difference. Since the motor's mounted all the way down, and I plan to raise it up one hole, I think I've got to get some more pitch. I stopped in Sarasota/Hill Propeller, and was told that it could be taken from 17 to 19 pitch, which would be about right. The price is $40.
Have any of you had any experience with this?I would appreciate any input.
Bigshot: if you're still looking for a prop, that could be an option, or you could have your spare aluminum re-pitched.

I have never had a prop of mine re-pitched but over the years I have sent many customers props out for a re-pitch. Never had a complaint.

I have had props sent to Mercury for tuning. I just gave them the detail of the boat, power, RPMs, and needs. The props came back doing exactly what I wanted them to do. They didn't even charge because they had suggested the props in question, they weren't quite up to the prefomance that Mercury thought I would be getting.
I even got some Mercury Racing Division bumper stickers with the deal.

I've had two SS props repitched in FL. Not sure where. But they came back fine and worked as promised. Not positive, but I think you can only do it with stainless. One inch of pitch is usually good for 200-300 rpm change.

Eric, good advice above! Assuming yours is a stainless prop in which case re-pitching works well...once! Bending the metal causes workhardening and a second repitching may break/crack blades. Here's a suggestion: have prop pitched up 2" and have it reconditioned/rehubbed and ballanced vertically and horizontally. This way you are "good to go"! Happy Whalin... Clark... Spruce Creek Navy

Sounds like a go, although I'll pass on the rehub. I bought the prop through my dealers mechanic, he said the prop was on a Ficht 115 that blew up with less than a hundred hours on it. I've only added about 30 more. I like the idea of balancing, I've had some automotive high performance engines balanced when I built them, and appreciate the dynamics involved in spinning an out of balance mass.

I have had many redone and always 100% satisfied.

Bigshot, Don't you carry your props to General Propeller in Bradenton, FL? www.gpcprop.com
posted 03-14-2002 01:25 PM ET (US)
yup! Pick them up usually the same day. They are cheap as hell.

General Propeller sounds good, I'll give them a try. Anyone have any idea if I'll pick up any top speed with the repitched prop? I'll be raising the motor one hole (currently all the way down), and I understand that makes a difference too.

I have gotten 44 on the GPS, but reliably can get 42-43 mph. I get a really quick hole-shot, the boat planes really fast. Would the repitched prop or raised motor make the boat take longer to plane, or require faster speed to stay on plane? Right now I can stay on plane at about 18 mph. That can be useful when I'm out in a heavy chop (that montauk ride again).

What is considered cheap?
I went to West Marine and they quoted me $108 for a SS 13 1/4 17 pitch to make it a 16 pitch.

That is because west is a rip. They send the prop to Hill or general and we get that job done directly for about $50.
Eric....I have a 19" you can try if you want. you have to join us at our rendezvous though.

I just came from two different prop shops here locally. Neither one wanted to repitch my SS prop. The second one did however trade me a 19 for my 20.

FYI for the local guys. The shops were Skips Prop Shop on Cross County Road, and Shepard's Propellers and Marine Service. Shepard's swapped with me. That guy is really good he'll talk you ear off and tell you every thing he knows. His price's are very good and service is prompt.

Bigshot, that's very generous of you. I'm working on getting there.
