Re: Lubricant for rubber deck gaskets

P'pepper, I'd say avoid conductive pastes at all costs! No graphite, no pipe dope with metal in it! Tef-gel is a good and widely used product that is not conductive- and is used on gaskets, threads and other applications. https://www.tefgel.com/contain.php?param=tefgel_infor another good process is ...

Re: Badly pitted Grumman canoe!!

Welcome to the AAB.com Forum, sorry its in these circumstances. As you might see from the posts and pics? the main boat here is plate so likely a bit thicker and of 5000 series aluminum? Not sure what alloy is used by the stretch formed, pressed boats like a canoe, but is pretty clear the aluminum c...

Re: Carpet Bunk to Roller Conversion EZ Loader 1925 Pacific

p'pepper, yep that's the general product- but some aftermarket bunk covers are 8' long so less pc to fit? maybe that image was just an example? I've also used different (cheaper) plastics but the ribs let water evaporate or run off. Long ago, before formed bunk covers- and under severe budget constr...

Re: Carpet Bunk to Roller Conversion EZ Loader 1925 Pacific

p'pepper, unless you add lots and lots of rollers- you'd risk more point load damage to the skiff bottom due to highway speed (trailering) impact- on the roller to bottom locations. I'd go with plastic bunk covers and all that's needed is to put them over the bunks- they're ribbed plastic that drain...

Re: Welding Around Fuel Tank

Craigb, while not intimate with the construction of all the Pacific Skiff models, the boats I've seen (on here) with welded in/integral tanks seem to be built with the tank top as part of the deck? So the top is welded to the tanks' sides with an overhanging lip/flange that is then welded to the sur...

Re: 2015 24' x 8.5' Lee Shore Boat Swiftsure 20 degree deep V

Dave, not sure if this matters in the boat's sale, but a note about the draft of the skiff shown with a 250 HP engine. I'd guess but don't know for sure that a 250 would need about 15-17 inches of diameter wheel to soak up the horse power? Of course with lots of pitch, I guess that could be smaller ...
