Re: Clean edge paint removal

Use heavy vinyl tape, a circle punch to make holes in the tape, place the punched tape over the problem areas, protect any remaining good painted areas with more tape, get some...

Re: Corrosion advice

Keep in mind that earth grounding from a hot boat can simply occur from boat to mud with no outside metal involved.

Re: Corrosion advice

Typically yes, even with the battery on it wouldn't make a difference if the boat was out of the water. If it is in the water (and the battery is on) stray current damage can occur in a tight area and very rapidly, shortest path to earth ground using the salt water as a pathway is the likely spot. I...

Re: Corrosion advice

On second look at your photo of the hole and your comments regarding electrical issues on the boat there is the possibility that the hole could be the result of stray current corrosion and not the galvanic foreign object suggestion I described above. If there is a weak DC+ short to the hull in the c...

Re: Corrosion advice

IMO standing water alone won't cause that problem however if a non-aluminum chunk of metal (like a stainless screw for instance) was resting at that point inside the hull and immersed in salt water over a long period of time then an active galvanic corrosion cell was created at that point that cause...

Re: Hull Pitting / Flowering

Its an older aluminum boat that is showing the cosmetic effects of being setup wrong from the beginning though it appears that no significant damage has been done so why all the worry? Pitting due to galvanics will likely stop when you fix the anode situation. The ultimate solution if you want to go...

Re: Hull Pitting / Flowering

Strongly suggest you replace those zinc hull anodes with aluminum equivalents plus add aluminum rudder anodes to the stainless tabs. Also be sure the main engine anode is aluminum. Agree with Kevin the flowering and pitting has other factors encouraging the problem but getting your anode situation s...

Re: Almar 22 sounder repower

I just noticed in an earlier pic that it had huge trim tabs considering the size of boat which would indicate that something was up with the handling. Are you planning to put those back on?

Re: Almar 22 sounder repower

My repower is roughly similar to yours, I pulled twin Merc 4cyl I/O's and replaced with V6 Zuke on a non-flotation bracket. Assuming your fuel is on centerline you will notice a huge tipping reduction when filled up. I carry 115 gals and it sits in the water like a '58 caddy when full but gets light...

Re: My 2009 Boulton Sea Skiff

Cool boat, if it doesn't have one already be sure to fit a decent sized aluminum anode on the transom if you plan to leave the boat in the water up in Canada to prevent galvanic corrosion.

Re: Corrosion Protection For Aluminum Hull Boats

These are all somewhat good ideas if not a little over the top in some cases, particularly since you don't have intention to leave the boat in the water. For instance your shore power isolation transformer would come in handy if you were planning on long term mooring in a decrepit marina full of poo...

Tariff's kicking in to curb china dumping, at $3.00 lb USA mills can re-open and a bunch of people can go back to work, in theory anyways. Bob, what percentage of a finished boat's cost is the uncut plate ordered for the job?

Re: Recent Chine Extrusion Experience

Kevin, one odd thing about the chine pitting is that the very tail end of the extrusion (last couple of inches) is unaffected. It appears that the welding on the inside of the hull is somehow altering the metallurgy of the chine piece? This is the fourth boat I've worked on with this pitting issue a...
