Hey him welding cracks and grinding them down is how I would do it the flatting out part don't understand does bottom of boat have some sort of grooves and price is good for where ur at
Depends on welder but for lil holes not to much aluminum is hard to weld can burn thru easy but good welder it will be fine u shouldn't have to prep anything the welder should do it
If I was the welder I would cut out the old and weld new piece in if good u can make it look factory as for hole a plate will do but for me I'd fill in hole while welder is there he can build it up then grind down flush where r u located I'm in Nampa idaho
I'll post pics when I get back home I don't know what I'll need for sei 116 alpha the stringer trim was electric and wad gear driven so I'll need rams that r electric or hydro don't know
I appreciate you thanks for all the advice and knowledge I'll keep u posted I had shift cable out it had big kink and 2 inches of it was exposed in water could this have been problem
