That doesn't equal a loss of 10 psi...... unless my math skills have deteriorated substantially.
If indeed there has been a loss of 10 psi- ALWAYS, ALWAYS start at the water pump. Don't forget to check the passages BELOW the water pump (especially the low water pickup passages) for wood debris that might be floating around.

Sorrry, was getting 20 to 25, now 15 psi
Since we're talkin' water pressure, where is it measured?

make sure when you pull lower unit off to check/change water pump have a look up inside exhaust housing, look up inside the tuner and see if you see gasket sticking out, i am seeing alot of gskt issues either tuner are powerhead gskt's being blown thus affecting water pressure
If I blew a gasket, wouldn't the boat be running bad?

NOT noticable to the common person, just saying if you have the foot off already save your self some headache and have a look up there
Pulled the Lu, impeller looked good, no gasket stuck, guess back to square one.
