Taking on water around pedals or somewhere other than cracks or holes

fibre glass repair kits are readily available from quality hard ware shops , marine shops and boating supplies and e-bay
there are plenty of youtube pages showing how to do the job
But if you are still hesitant about doing the job yourself take the boat to a marine dealer or shipright and have the job done professionally

Find the leak and patch it. Use a good marine epoxy system with a sheet or two of fiberglass cloth laid-across the crack. Be sure to sandpaper the area thoroughly with rough paper. If you can't find a leak or crack, fill the hull with water and inspect for leak. Repair after.

Aluminum boats are easier to maintain, will last longer than fiberglass, and are easier to repair. You can also bump into things without causing damage like you would to a fiberglass hull.

The only real advantages to fiberglass are that it looks better due to the gelcoat finish, providing that it is maintained, they also feel more solid in the water due to the extra weight, and they tend to ride better and are quieter than an aluminum hull.

One other consideration is whether you will operate it in fresh water or salt water. Salt water can lead to corrosion problems on an aluminum hull if you leave it in the water. Fiberglass doesn't have that problem, but you can have a problem with blistering if you leave a fiberglass boat in the water for long periods, especially if you don't use a bottom coat of some sort.

If you do opt for an aluminum boat in salt water, just make sure that you spray it down with fresh water and wipe it down with a soft towel whenever you take it out of the water. This is actually a good practice for any boat, aluminum or fiberglass.

If the boat is Fiberglass, it can be repaired with fiberglass Matt and resin.

hi is the hull made of fiberglass, if so you can normally buy these type of repair kits from car spares shops, they include fibre glass resin and sealer, good look.

I used ABS, PVC combination plumbers glue, the kind they use to put plastic waste pipe together, to patch up 2 small holes in my plastic pelican boat. It seems to melt on, so far so good

It depends on the material of the hull. If it is Fiberglass then buy a small auto or boat repair fibreglass kit and follow instructions in the kit.
. If it is one of the engineering thermoplastics like High density Polyethylene ABS or Polypropylene I would try and find somone who can weld it with the appropriate material. This would be done by carefully shaping the plastic away from the crack to form a "V" shaped recess and then filling the gap with the appropriate filler rod usually using a hot air blower designed for the job.

Unplugged water tube, cracked water tube, bad drive shaft hull seal, hole/crack in the hull, cracked water box, broken exhaust jacket water seal, water tubes plugged in incorrectly, no cap on flush kit, broken fitting on motor,etc. Dry out the boat take off the seat and place it in the water and look to see where the water is coming into the hull.

V out the cracks with a grinder, cut fiberglass matting with an overlap of about half an inch. pre-cut 6 more pieces gradually stepping overlap to 1 1/2 inch starting with smallest piece soak in resin and place over v'd out crack, once all pieces are in place press out any air bubbles. takes a while to dry. once dry sand flat with 36 grit then 80 and 150. place a gelcoat on top
