alarm going off on my gambler

[jason s]

i have a 1998 intimidator with a 98 merc 225 promax. has para lift jack plate. when i take off and run trimmed down it is fine water pressure is at 30. when i trim up and speed up my alarm goes off. i do not have low water pick up but i have my jack plate all the way down. what gives? cant get any speed at all

Is water coming out of your motor at speeds?

When was your last water pump change?

[jason s]

it does until i trim up. just got the boat only had it on the water a few times

I would change your water pump. Whenever I buy a used boat I change the water pump and gear oil.

Do you have a water pressure gauge? I'm not sure about the older boats or promax's, but the alarm on my boat will go off for numerous reasons. The most common being low-oil related. Is it a solid beep or intermittent?

I am going to change the water pump this weekend. I do have a water pressure gauge and the more i trim the less psi i get. i mix my own gas and oil took the injector off.
