I have a mark IV 454 that has the mercrusier cast aluminum pan p/n 47552 on it but the previous owner put a universal dipstick on it that I dont believe is accurate. I was wondering if anyone is familiar with this setup. Only info i can find is its a 7qt pan. If it is does that mean the engine takes 7 qts total or 7 1/2 qts due to the filter and cooler?

I have a 7 qt stamped pan. When I do an oil change I buy 8 quarts. 7 go in the pan and most of the other goes into prefilling the filter.

that pan holds 8 qts.i have them on my 1990 sea ray with 340 hp engines.they were also used on the 420 hp engines.

Mike tkach when you do an oil filter change 8qts is all yours takes total and its full?

Drain oil, change filter, fill w/ 8qts, mark it, run engine for a bit, check oil, add accordingly till at previous mark.

I've got the same ones. Couldn't have said it any better.

yes,it will show slightly over full but after you start it and wait a few minutes after shutoff it reads to the full mark.

Mike - novice question. In checking the oil - should the boat be in the water or is on the trailer/lift etc., ok to get an accurate reading??

thanks
