On the subject of AL gas tank leak repairs...
On another website that I haunt someone was telling about their AL gas tank leak fix...
Screw plate over the leak on the bottom using...brass screws and 3M sealant on the plate!

RE: Bert... sigh... reminds me of the Bert25 I/O softtop I lost in a divorce. Had just fixed some minor hull items, removed all the previous owners "improvements" cleaned up some wiring issues and was new engine/drive shopping.

BTW...Good talking to you yesterday
