Bolo<br />I do not know about your new problems. The overheating problem with riser plugged means very close to the point where manifold fails and water runs back to the exhaust valves and into the clyinders. If your going to run it without changing manifold watch it very closely.

Could be gear oil from your outdrive, or hydraulic fluid from the trim lines leaking. I would think you would want to pull the boat and find the source. <br />You might be able to tell on the hydraulics by stopping and turning everything off. When the water clears run your trim all the way up and down. If you see an oil slick it is likely oil leaking from your trim. Check the reservoir if it is low that is also a clue.<br />Water leaking into your outdrive will turn into a major repair real quick.
