- 454 CID / 7.4 Liter Twins
Hello Folks - Had my local marine tech change the oil on both engines upon purchase of new boat to me last year. - 1990 Sea Ray 350 Express Cruiser with twins
I instructed him to put in 7.57 litres / 8 quarts.
Yet this showed way overfilled on dipstick on both engines- had to remove approx 2 litres / 2 quarts from each which brought each dipstick to top of fill mark.
Owners manual ( Mercruiser 454 Service Manual #15 - Section 1b-10, page 23) reflects as follows:
7.57 Litres / 8 Quarts With New Filter
or
6.60 Litres / 7 Quarts With New Filter - For Generation V Engines (Engines with Cast Aluminum Rocker Arm Covers and lack of engine block fuel pump mounting pad)
I was never aware of / had read of a 6.60 litre / 7 Quart Gen V configuration
Makes sense if my engines are Gen V but how can I be 100% sure?
I think I read Gen V came out in 1992 whereas my engines are 1990.
Can anyone assist?
Engines Are:
7.4L MIE W/HURTH GM 454 V-8 1989-1992 - 0C391564 THRU 0D715493
Thanks - Craig
