I need help with low oil alarm on 150hp 2 stroke 2001.If I run motor under 3500rpm no problems runs all day no alarm if I get to around 4000 rpm low oil alarm comes on when engine tank runs down causing this alarm.If I top up engine tank alarm goes away but comes back on if I sit on 4000rmp for around 30 minutes. This has been happening for last 18 months and is starting to drive me crazy.Any suggestions greatly appreciated.

Not enough oil being transfered from boat oil tank, check if oil hoses are pinched on back side of oil tank where fits into bracket, check oil filter on same tank and check oil transfer pump.

quick test.
key on engine off.
make sure remote tank at least 1/2 full and all 3 bars,arrows or green lamp on tach is lit.
now drain engine tank via the water trap until the audible sounds.
turn key off and replace water trap.
turn key to on DO NOT start engine.
visual on tach should display all bars blinking, transfer pump will turn on and stay on for 180 seconds.
engine tank should refill and pump turned off before the timer runs out.
if not find the restriction.
