i think most of the responses here are saying its a bad idea to spend all your time and money to fix an old boat that has been left to the elements and with a broken motor as well.
you will get plenty of experience doing the resto so go for it , there is plenty of good info on the internet , there is also lots of bad as well.
start with a total strip down to bare bones and assess the project from there. look at the cost of materials and incidentals , they are expensive , you will also need special tools and extra tools most people do not have on hand for things like the drive and fiber glassing. shop trolley build to move it around , a step ladder is also a must
.
at that point that is where you can say with confidence if the project is worth all your effort or not.
look at the big picture ,? is the boat what you want , ? is it going to be as good as you are going to be expecting when all your time and money has gone into it.
keep the tread up to dat as you go and ignore the nay sayers unless there criticism is constructive appreci
