i boat on a budget like most of you and have a problem <br />a few weekends ago i hit something in the water and damaged my lower unit (86 alpha one) <br />i have a pre-alpha lower unit sitting collecting dust <br />i have set the 2 drives next to each other and the only difference i can see is the pin on top of the drive shaft of the pre-alpha and the rounded cavitation plate , splines match on both drive shaft and prop shafts , and measuring both are identical. <br /><br />will it work? , do i need to remove the pin on top of the drive shaft? <br />any help would be great. <br /><br />thanks in advance
