Need spare props, 4788/490, PNW-gctid827095

[Cptmorgan]

I'd like to have a spare set of props onboard before we head out next spring. Anyone have a reasonable source for spare props in the Pacific North West? Anyone have spare set in the garage or lazarette that you're looking to unload?

Edit: 4-blade Nibral Nakamichi 24x24 2" shaft are OEM on the 4788s and 490s. Ideally, I'd like something already pitched to around 22"-23", but I expect I'll need to balance and re-pitch used props at the local shop.

Thanks,

-Morgan

"The prop shop" can supply you with a set of the original nakashima props, cast in any pitch you want.

If your boat is not quite pitched properly this is a great opportunity to make it just right.

The cost two years ago was about $3700 for the set.

What shafts do you have? I have a set of 1/34. See my add in classifieds..

Specify the shaft size and the pitch, and the number of blades.

Makes it much easier to assist.

You might be surprised what you can find on ebay.

I bought a pair of 4 blade nibral's, new for $350. for my 3870.

I also bought a pair of 3 blade nibrai'sl very good used for $250 used.

Morgan's ultimate required best pitch is going to be determined by his exact engines, his current baseline, and the specs on the exact props he ends up with.

In general I believe most 47's will be nest served with a 24" Diameter and 20.5-22" pitch 4 blade nibrals with a 2" shaft.

Knowing his current baseline props and numbers will allow a good prop shop to determine the best fit.

Baseline numbers for the prop shop include: boat length and beam, weight of boat, transmission ratios, exact engine rated rpm and hp, current accurate rpm speeds at a few data points (100 rpm apart) approaching WOT and a WOT rpm number for both engines.

For spare I got bronze props instead of the more expensive Nibral for our 47 20 years ago.
