Re: Hull registration no

Looks like the old Coast Guard numbering scheme. Coast Guard small boat registration was turned over to each state sometime in the 1950s? My 1932 Hacker was 13P152. State registrations use abbreviations like MD for Maryland or AZ for Arizona, etc. Also, when there were only USCG numbers, no yearly s...

Re: 1938 gas tank restoration

If you have a tank fabricated, just be sure the outfit that does the work has a U.S. Coast Guard endorsement. Some outfits will fabricate to USCG specs, but unless they are certified to do so, steer clear. The new tank will have a code plate attached, and the work will be traceable regarding materia...

Re: Torque that manifold

Steve... The process with the spray cans is a "liquid dye penetrant test". I used this process to examine welds when I worked as a supervisor at a nuclear power plant.

Re: Shaft Packing '42 Special Runabout

That appears to be the keyway. The setscrew should engage a depression or "dimple" which is usually machined into the shaft using the coupling as a drill jig.

Re: Shaft Packing '42 Special Runabout

A good opportunity to inspect the condition of the cutless bearing, as well. Also, be sure that the shaft is not fretted from over-adjusted packing. Usually, when packing wears, and loses its impregnated lube (usually wax), the tendency is to pull the gland up tight in an effort to squeeze a few mor...
