Algae doesn’t seal it.I have a boat that has been in the water at least 10 years possibly 20. On a freshwater lake with higher salinity level. If clean the bottom off, do I run the risk of having to repair it? Is the algae keeping my bottom sealed?
No. If it were my boat, as recommended by the other posters, haul out and pressure wash the bottom, which should expose any necessary repairs, such as blisters, pockets, etc. If that part checks okay, my next step is to prep the hull for two coats of ablative bottom paint. Prep the hull depends upon whether the hull has ever had bottom paint applied. Different steps apply in either case.Is the algae keeping my bottom sealed?
Yes, maybe... depends on the engine. Uncle parked a tractor in the corner of his field. Passed away after an good lief and final illness. 10 years later, his son became caretaker of the family farm. While exploring the large blackberry briar patch in the corner of the field discovered a tractor under all the old growth. Weed whacked a path to the tractor. Stuck a new battery on the tractor. Poured in some diesel, oil and the Perkins engine fired right up. Drove the tractor out of the patch and to the barn. A little maintenance cleaning and the Perkins is ticking away on the farm.Could an inboard engine survive that length of time unrun?
These look a little tough.Are zebra mussels tasty?
There are alternatives.I'm guessing after 20 years it's going to take more than pressure washing!!
Ahhhh.... you can't unsee somethings. My eyes .... my eyes.
Yikes! Any reputable yard can clean up that hull quite nicely. I've seen some hulls like that and even worse, but even so a yard has the equipment to deal with it.This would be extreme
We need to know the PHRF value...
