Hey,
I just hit a rock with my prop on my 1986 210 Scorpion. The boat has a 260hp Mercrusier with a Alpha One.

Any suggestions for a replacement prop? What size and pitch prop do you have on your Chris Craft?

Thanks,
Bob

I have an '88 scorpion with the same engine and outdrive set up, I went with a stainless 17" pitch prop to get out of the hole and on plane faster. I had to replace the anode with a flat one to clear the prop, also I added a fin to the out drive and now wish I would have stuck with the original 19" pitch, but it does get on a plane very fast, I am thinking about a 19" 4 blade stainless prop to replace mine now to try to get more top end speed, I hope this helps a little.

Bob, I am not home now, but will look at what my prop is, do you have any photos of your boat. I would love to see other boats like mine? Arthur

Anybody know what came on the 350/Alpha combo stock?

My '84 210SL has an unknown prop on it currently -- no numbers, no nothing. It needs to be replaced, and I have no idea what the specs are on it.

Bringing this back to life!!!

I ended up just putting a 15x15 on it last year,
so, a few are running a 19P prop?

So is that 15x19?

Someone said I should run a 14.24x21?

Any advice is greatly appreciated
Thanks

Sadly there is no magic formula or graph that can recommend the exact prop.
Trial and error is the only way to go.

I would start with a 17 pitch and work my way up to about a 23 max. The diameter is another thing to consider so maybe start with your 14 you have and try a bigger one and see the difference in rpm at WOT.
To get out of the hole you need a smaller pitch, but for top end you need higher pitch.
WHAT IS IT YOU DESIRE???
Good luck and hope you find what you need.
