I up graded my trim tabs with 12X18 blades on my 2510 and the other day I noticed that the port blade was dangleing. After further inspection I found that the hinge pin was gone. There was a rust stain at the hinge. Did the pin rust away, the tabs are less than 6 months old. Did Lenco not use stainless steel for pins? Anybody else have the same problem? I noticed that the other side also has the same rust deposits at the hinge. I found some 1/8 inch brass pins that might fix the problem any help would be great. The old lenco blades I took off 6 months ago had been on the boat for 6 years with no sign of wear. paul
