I know that mercury does not recommend sandwich brackets( which i have). Just wondering if anyone on here has any tricks to help me out. Im not sure what other style you could use with the detweiller hydraulic. Problem is, the bolts between mptor and jackplate ( through the bracket) get loose on every trip. Noticed yesterday, that the bolts between jackplate and transom were actually loose. Going to re- silicone and tighten all 6 of those today. Any ideas on how to stop this?
