I have a 1999 Malibu Response with an Indmar 350 EFI. I am by no means a mechanic but I understand the basics and I am trying to get some guideance on where to start. I am having someone else do the work and am trying to point him in the right direction. Engine oil becomes milky after very little run time. At this point multiple things have been done to the engine.
1. We have pressure tested the block. No signs of a leak.
2. Replaced Intake Manifold.
3. Replaced head gaskets and head bolts last year. But since that time the boat overheated due to an impeller failure. Should we look in that direction again?
What steps and in what order would you suggest us to troubleshoot. Your help and guideance is very much appreciated.
Thanks in advance!!
