You may have been reading absolute pressure. Did you have a reference line to somewhere outside the engine compartment? If your elevation was somewhere around 4000 ft or so, this would be about right. Anyway, the boat woudn't hold 11 psi anyway without exploding. The bottom structure would, but decks and superstructure are usually designed for 3.5 psi or less. Even a residential 100 psf floor load is only 0.69 psi.

Here is a simple video to explain this delima

That guy's a character. I bet his class would have been quite interesting.

or possibly I had the scale incorrectly set and it was 1 point 1 psi?
