I知 almost done with my 100hour maintenance and have found some items I need to fix. If anybody has knowledge of these items let me know. The engine is a KAD300A it痴 close to the 43 and almost just like the 44.

1. Raw water pump is leaking rebuild or replace? Who has the best price?

2. Fine oil residue in the bilge and in the air cleaner housing. Could it be the oil cooler?
I知 also getting some blow buy after Blackman did some topend warranty work

3. How often should I have the injectors cleaned? Can I do it myself? I知 getting a good amount of smoke when I first fire the boat up.

4. How do I clean the oil cooler? The owners manual states it can be cleaned but dose not explain how.

Thanks Joe
