Best all around prop for a 70 Separator?

Is there a 12" on it now? If so, I would say a 12x14 would be a starting point. I'll email my friend who has the blue (original color!!!!) torino and see what is on his.

It's got a 12" 3 blade bronze - pitch unknown. I'm going to have a nick repaired so I thought I might repitch it while it's in the shop and maybe go for a new one if that's not feasible.

No - no problems at all with the prop - it's slow to come up on plane but I'm not going to pass judgement until I get the carb working right and put some tabs on her. I expect she'll always be a bit slow to pop up being a rear engine boat.

Hmmmmm? Wow, those numbers seemed way outta whack until it's considered that this package has a reduction in the v-drive, as informed by Woody. Geno, I'd still want to start with what's on there now like Pete said. Have you looked on the side of the hub really well to see if there's anything there?

12" Dia is what it called for because the 13" was too close to the bottom of the boat and caused cavitation.

If you have the 290 hp you will need a Nibral 12x17SC-12x18SC (SC is Super Cup) to keep your revs in check (4800). Yes they are real slow out of the bucket but man do they run on top end.

8122 What do you mean by early Crusaders? Years?
Larger Diameters?

I'm going to get the carb right, install the trim tabs and get her back on the water to see what difference that makes. I'll look at my prop and see what's on it late this evening.

Pete - the paint is not coming along at all at the moment - haven't been able to get to her in a while. We have decided on the yellow color all over though - Yucatan Yellow I think it's called

One of the problems especially with early and low production CC's is there wasn't that much consistency. Many times they used what they had on hand to complete a boat. A good example would be the deck scoops. Some were purchased and others were CC's own fiberglass versions. As far as early and late, all I can say is pre 70 and post 70! You must have a later V drive with the reduction with prop pitches of 17 and 18. How about posting some pictures of your boat? Do you know the year of yours?

A early (let's say 68) will have exhaust risers forward and then the hose going under the engine and out the transom low. Later the risers were aft and very short sections of hose went out the transom high. These were the very loud ones!!

Ok...that makes some sense. The Seperator I have is a Autumn Green 1970 Spoiler it does have the crusader vee drive so I guess it could have either ratio vee drive.

The prop that is on this boat to keep it at about 4800 revs is a Federal 12x19RH SC

I have SPOILER on the transom only...It is painted
