When I checked the oil port motor and tried to reinsert dipstick back it would only go till about 2-3 inches from all in . Don't know if anyone has had this happen? Switched the sticks and will go in the starboard engine fine.???

bent or kink or pinched oil dip stick tube just above the oil pan ? or blockage of some sort going into the pan ?

Thank you yes I just don't know yet I will have someone check for me.

Must be block cause able to put in the starboard engine fine. Just don't have much idea how or why this might happen weid?

just a try turn your dipstick 180 and reinstall, did that help ? test with both dipsticks

wonder if the dipstick tube has started to come out of block. if so you will hit the "land" machined for the tube. Gentle tap on end of tube with piece of wood might fix problem

Excellent advice - this happens to a ton of motors - not just Mercruiser 575's. It's part of the daily life of those who work on anything with an engine and a dipstick. LOL.
