It's very solid and there is a little lip for the next part to rest on.
Bill jumped on the 23 Tsunami and started a hacking and a hewing. He cut out the lip around the engine cover and ground it down flush. More pictures to come of that later.
Bill is badly infected with SeaCraft restoritis. You should have seen the fiberglass dust flying out of that boat. The next day I asked him if he itched at all and he replied No. So either he is lying or immune to fiberglass dust.
