What pressure should I be at on this motor..og486942...Thanks
1-4.5 psi @ idle speed
9-10 psi @ WOT
Do I need to go with a torque master do to the upgrades???

Only 9-10 http://www.bassboatcentral.com/smileys/doh.gif
No wonder my water pump looked good and I never overheated. I thought my pressure was low http://www.bassboatcentral.com/smileys/Laugh.gif
The key is whether or not the gearcase is equipped with low-water pickups.
Models with low water pickups (2001-> models, with a few earlier exceptions) will achieve a minimum of 15 psi @ WOT. http://www.bassboatcentral.com/smileys/wink.gif
The 3 liter engines of that era use a high volume/ low pressure pump. I have the same exact motor (1997 Mercury 225 EFI) and Don is spot on!
