Props

My first post: can someone please offer me advice on what new prop to buy? I ran my 07 19' Cruiser through a shallow, sandy, rocky bottom of our lake and messed up my prop a tad.

She runs differently, more roughly now. Vibrations across various rpms. I assume a new prop is in order for my Yamaha 90 4-stroke. Am I on the right track? Where might you direct me to make sure I get the right replacement unit (assuming that is the right diagnosis)?

Thank you.

Sorry to hear. A lot of us have done that and more will yet. A bent prop will really shake things. Don't run it till its fixed. If it is aluminum have a prop shop look to see if it can be restored. If its really shredded replace with same pitch and diameter from your dealer. I dinged a prop a couple years ago and my prop guy had it looking new quickly. Hopefully nothing in your drive train was bent. If anything feels funny or shakes with a new prop it may have bent things further up. That's why I like alum props as they will fold themselves up and spare your drive train. A ss prop takes it fine and destroys 3 grand worth of drivetrain. Best of luck. A lot of us have found the beach. George.

If you didn't know before, you're certainly learning about running in the shallow water off the east coast, even if it was a lake. So don't panic and take your time getting it fixed, you'll be there again.

So, George said something that I want to repeat: "If it is aluminum have a prop shop look to see if it can be restored." Even if it's stainless, find a prop shop to restore it. You'll meet someone who not only fix that thing, but can help you select the correct pitch and repitch it if needed.

I found a good prop shop in San Diego, Vancouver Isle and Miami. I'm certain you can find one near home. Google search, ask around, but don't give up.

Good luck, Boris

Always carry a second prop (or back ups if twins)...Agree you don't want to run the unbalanced or damaged prop to avoid seal and gear box damage.

I like SS props over AL, but the current boat came with one used and one new Aluminum, so I'll have the used reconditioned, and stay with the new one. If I ding it up badly--it happens--then I'll get a SS prop. SS do better with minor contacts with sand etc--but since they don't give, it can cause gear box problems. The aluminum prop flexes more, and will ding more easily.

Welcome to the C-Brats. There is an abundance of good advice and good friends here. While many are more knowledgable than I, few have mangled more props. Murphy's Propeller in Norfolk, VA has done a lot of work for me. I've had them repair stainless steel as well as aluminum props. It's amazing. Gnarled-up props come back looking like new at half the price of replacement. I'm sure a prop could be beyond repair but, so far so good for me (knock wood). I also recommend keeping a replacement prop (and the tools to replace it with) on your boat.

Hope this helps. http://www.murphyspropellers.com/ Thumbs Up
