Re: New to boating
Jimmyboy,
The keel can be repaired pretty easily as stated above, grind 3-4" on either side of damage and lightly grind damaged area trying to round the square edges slightly 90 deg. corners are hard to deal with. Layer up woven roven or mat, then finish with cloth to attain smoothness. Don't do it all in cloth it isn't strong enough. Once fully cured sand smooth clean well and paint. Acetone is great to clean every step of the process with you dont want ANY dust, oils, grease, wax, etc. to compromise a good bond. Once all has cured then attach keel guard and you should be good to go. Couple notes try to do the whole length of the repair at a time not in pieces, if need be I would think you could jack the trailer way up even put blocks under jack. then build a block to hold boat up(2x4 with v in top or block up to chines from ground) then lower trailer to access all of keel needed. Obviously this needs to be well thought out and safe if it doesn't seem doable then don't chance it.
I didn't know you were in freezing temps when I reccomended the tap test. I would try to get the boat into a heated garage let it all thaw out then you can do some real investigation into that transom. I don't want to sound negative and hope I just cant see pics well enough but that transom looks to be in bad shape. Lots of gaps unsealed holes rust looks like silicone on the mounting bracket bolts. I would for sure know exactly whats going on back there before I did any serious boating in it. If you are just trolling might be okay with a few repairs but I would check it out if it were me because its hard to drive around and not drop the hammer to see what shes got then the next thing you know the outboard is on the bottom of the lake with your boat soon to follow. Just be safe is all I'm trying to say. Post back with findings or questions....
