Help!!! So I take a friends Chaparal out for a weekend trip. Long story short... I hit a hunk of Concreete with the prop and Jacked it up. Now I have to get a replacement prop for him pronto...<br /><br />Question.<br />I have 2 different props from a Mercruiser that are the same specs. 19 Spline, 14 1/4 x 21 degrees. Looks like it will fit. Will it work? Or do I need to start shopping for a prop???<br /><br />Engine Specs: Volvo Penta 4.3GL PEFS<br />Drive Unit: SX-M 1.79<br />Transom: TSK SXMCT or SXMLT (couldn't see that one digit...<br /><br />Thanks in advacne.
