Ted: I've seen on other boat heat exchangers that one method to clean out the barnacle and junk accumulated in the raw water tubes is to remove the raw water inlet & outlet hoses, plumb temporary hoses to a large clear plastic tank, and circulate a solution of barnacle buster and distilled water with a small recirc pump for about 3 to 4 hours. Do you not recommend that in lieu to taking off the heat exchanger and then removing both end caps and using the 22 cal bore brush, etc? On all my boats I have never had a problem with my heat exchangers as I always run salt away on the raw water side to flush at the end of every day of boating. As I am about to purchase a new to me 4 year old boat that one doesn't see that the current owner was religious about maintenance, I was wondering your thoughts?
That method works, I've done that on old raw water systems. I Reverse the hoses a couple of times and always start by backflushing first. I've heard mixed reviews with salt away, not sure it's a good as it sounds.
Ted I enjoy watching your videos, keep em coming! Any time you (your students) work on the 380 gas engine please post.
It would be great to have the o-ring part number in the video, but Thanks for posting
Wow that looks easy in the shop. Try it on a regal 28 express. Much more difficult
Agreed, much different on any boat. I am spoiled in the lab.
Ted. Do you have an email I can send a pic of the thermostat out of my 2016 gen 5 300. It's bizarre how the seal ended up through the stat.
@dhorne902 Sure thing pics are always welcome!
