Subject: [amphicar-lovers] First swim
</font>


<tt>I took the amphi for its first swim today which was successful, even
with the 4 or 5 leak areas. Unfortunately, the bilge pump didnt work
so I had to make it short.

One thing I noticed was a tremendous amount of pin holes and leaking
coming thru the body directly behind the jack plates. It also looks
like there may have been some filling in with putty there... has
anyone experienced problems with rusting or holes in this area?

<tt><span class="765424301-19122005"><font face="Century Schoolbook" color="#0000ff" size="4">The jacking plates were a bad design idea. The plates are quite strong, but they were tack welded onto the hull at about 5 points. That left athin gapthat water could get into, between the jacking plate and the hull. Even if thoroughly painted, the steel in the gap was exposed to the water. On my Amphi, I could see only some slight paint blistering, about an inch in diameter, on the inside of the hull over each jacking plate. To get at all of the rust, I eventually had to grind off each jacking plate and ended up with 4" by 10" holes in the hull. (PIXS sent off-line)</font></span></tt>
