Re: 1997 Bayliner Capri 1750 ls 3.0 litre stock Prop Size?
From Bayliner's 1997 1750 Parts Manual:
3.0LX ALPHA I (EK3)
ENGINE SYSTEMS
* 62236 3.0LX A1 1.94 SD EA 1
* 14691 13-3/4 X 21 PROP-MERC I/O EA 1
But, if you have any prop at all, I'd test that, before purchasing anything.
If starting with none (after verifing drive ratio 1.94), the 21P would not be a bad starting point for cruising. A 19P would be a better starting point for pulling water toys or heavy loads.
