Dont take achaxe wiht a leaking tank. I did not replace my tank... yet. Risky... mmm.... yes... and I have been telling mysefl to do it. Probably this year. Fortunatly it is not leaking and is in amazingly good shape. But yes , its 36yrs old. So, that should be enough reaosn for me to get it out. Check with cdwood, he got one for his when he did his transom.
