stock prop 72 omc 225hp

[oldbow]

I have a Century Raven 19ft model 980064. 307GM 4brl quad. Does anyone know Dia. and Pitch for the stock prop?<br /><br />I'm also changing out rusted steel fuel tank but can't find a comparable. It's a 48 gal. 87Lx16wx8d. Closest I can find is a 35 gal. from Moeller tanks. Want to run it until it sells.

I believe those electric shift drives used 14" dia props. Pitch would vary widely based on boat.

Thanks Rainmaker. 2 boat shops. One said 14x16 pitch, the other 14x21 pitch. I'd rather have cruising not out of the hole torgue. Would that be the 16?

Nope, that would be the 21. However those electric shift OMC drives(I have one) are pin drive. They are not recommended to turn Stainless Steel props(to heavy), and the aluminum pin drive props available for them are usually 14 X 14 - 14 X 20. I haveent seen a 21. Be careful you are getting an aluminum PIN DRIVE, prop.

Thanks Mahoney: After reading the prop info on Iboats I realized that. Do you use a 20 pitch? A reference number would be much appreciated if it's covenient. I have a Michigan on now, no. pr120?

I am actually using a 14X18 Aluminum from propco, really cheap props. I am going to get a 14 X 20 as I am still able to turn about 4800 RPM with my 18 after tuning up that 30 yr old 225.
