having the replace the element in it. Then having to replace the salt water pump on the engine and then having to replace the heat ex-changer and then having to replace the injection elbow! All these things things coming at the same time. I used the boat for a raft up with the club two weeks ago and when I got back to the dock I checked over the engine before putting her to bed for the week and noticed the hot water tank dripping. Then while working on it I noticed the salt the salt water pump weep hole had dripped. Then after replacing it and running the engine I noticed the injection elbow. Then I noticed the expansion tank blowing a few drops water past the cap. I put a pressure gauge on the cooling system and found that it was at 15 pounds instead of the 4 that it was suppose to be indicating blockage in the heat ex-changer. So, I went through my spare salt water pump, my spare injection elbow and my spare heat ex-changer in two days! Shit!
