Hello - I have just performed my first oil change on my Graymarine Phantom Six - 104. The previous two changes were done by an engine restoration service and then by a boat restorer. The specs (Gray Marine manual) indicate an oil volume of 9 quarts for this engine. The oil dipstick reads a little over full after only 5 quarts. In addition, the running engine oil pressure is ~40 also on only 4.5-5 qts. When asked, the boat restorer indicated they likely only put in 4-6 quarts when the engine was winterized last year. As a result, I was only able to remove about 4-5 quarts when the engine was warm.

What is going on here? Either 4 quarts of oil are hiding somewhere or the engine appears to be full on only 5. Anyone else have this issue? Does anyone have a picture of their Six-104 dipstick to see if someone changed mine (although very unlikely)? I don't want to stuff 9 quarts of oil into the engine if the indicators say its already full.

From what location are you removing the oil? Are you removing the transmission cover to suck out the oil?

Hmm, .... Gray flat head six, about 226 CID. Nine quarts is about right (goes into the reverse gear also).
