Noob here, is this enough damage to cause problems? Recently acquired barn find 650sx, was told it didn’t drive forwards very well

Hard yes

[u/regiment9ine → u/ApprehensiveWatch786]

Thank you, this what I needed. Car and moto guy but lots to learn on marine stuff

[u/scubas1973]

That is badly trashed. Replace with a variable pitch stainless prop and it will perform better than ever.

Yep!!

[u/604whaler]

Yes. That would barely move.

You need a new impeller and wear ring at the minimum

[u/fiveho11]

Yes

[u/ThisMemesWar116]

That is a mangled stock aluminum impeller, they are crap. Look for a stainless replacement.

[u/SpringFuzzy]

There’s a reason that thing was sitting in a barn

[u/RedditAppSuxAsss]

Yes, yes, and yes.

Replace or have it professionally fixed.

[u/cleetusneck]

So the wear clearance between the prop and ring is usually 5 thousands- and a human hair is like 3 thousands.

Small dings can be filed or ground down, but any bent props or chunks missing (and you have both) its replacement time. Look at Impros for recommendations.

Usually the prop and ring are replaced as a pair. Try not to eat all the rocks in the lake, and I could do the bearings and seals at the same time. If the bearings go it usually tears everything up bad enough it’s junk.

[u/-Mx-Life-]

Absolutely.

[u/kiriyaaoi]

I had a stock impeller with a barely damaged leading edge and had massive cavitation problems. That impeller will probably barely move the ski

[u/CompetitiveYou2786]

More cavitation than a mantis shrimp
