All about marine salt h2o cooling systems, impeller, warmth exchanger, salt h2o pump- Up-to-date





A rambeling “present and notify” discussion about how and when to modify a marine salt h2o impeller, how a lot steam and smoke ought to arrive out of a marine engine, how to acquire a warmth exchanger apart, how to clean up an exhaust elbow, and why a salt h2o pump has a gap amongst bearings.

This is an up-to-date edition after we manufactured the comprehensive fix of the exhaust system.

  1. Very informative video, thank you for sharing. I got confused though at the end when you show the exhaust elbow with the raw water cooling combining into the exhaust – why does the water also not come out of the side of the boat? If the exhaust and cooling water are combined at the elbow, at what point is this separated again prior to exiting the boat?

  5. Great video, Scott! Lots of good info on the cooling systems. Have you ever performed a raw-water cooled system flush with Barnacle Buster?

  7. Nice…..just a suggestion what about a ultrasonic bath to clean the elbow part. The water flow sensor isn't worth a damn if it doesn't measure actual flow another maintenance protocol on the checklist.

  8. Thanks for the video. Two questions: 1) what kind of grease do you like to use for the impeller and screws. 2) You mentioned not wanting to use steel screws to secure the pump plate. What is the preferred material? Bronze?

  13. Very helpful.

    What is the easiest way to remove the heat exchanger (Northernlights generator M643)? I removed the bolts and tapped it with a hammer, but it seems stuck. I don't want to break it.
