Fantastic video Ron. Replaced my damaged prop prior to watching this video and experienced slight vibration starting at about 20-25% power. Was about to waste a ton of money replacing my prop shaft but saw this video, removed/reinstalled the prop following your instructions and voilà: smooth as buttercream. You are truly an invaluable asset to the entire past, present and future ski boat community.

Thread pitch and size on the shaft nut? I lost mine and luckily the prop stayed on!

[@mikerostine6253]

Can be many reasons for vibrations?
Looks like an OJ prop.

What’s a key weigh? About 1/8 oz.

[@mikerostine6253]

You can use a beveled edged key.

do you lap props to tapered shafts?

[@sylvainlaviolette7852]

whats the torque on the nut?thanks

[@LakeMountD]

I was going to ask this exact question.

[@lennyhardy3470]

What is the torque on the prop nut?

[@rontanis1024]

I've never used a torque wrench to tighten a prop nut, I use a 1/2" breaker bar & make-em tight

Thank you Ron! You're a great asset to boat owners!

ACME recommends just 50 foot lbs.

Can you install the prop backwards?

[@rontanis1024]

NO, not props with tapered shafts, some of the newer ski boats have splined shafts & I suspect they could be put on backwards
