2013 MB B52 (Indmar 5.7L/350). Completed my first winterization on my own and looking for feedback to determine if I missed any steps. Thanks in advance.
1. Poured 8 oz of marine Stabil to full tank. Ran engine (fake a lake) for 15 mins.
2. Removed exhaust manifold disconnect and drained.
3. Removed both hoses from impeller housing and drained. Removed impeller (35 engine hrs) looked brand new. I have a replacement impeller, but will likely re-install existing impeller in Spring.
4. Removed 2 bolts from Ski-Vee (bow side) per Indmar manual. Anodes look new. removed hose on port side to Ski-Vee (from raw water intake). Removed starboard hose that goes to impeller housing.
5. Removed and clean raw water strainer. Drained water and replaced. Seems obvious but this step was not in the Indmar manual.
6. Removed knock sensor from port and starboard on lower block. Removed bolts and drained block. Did not re-install bolts.
7. Hooked up single bank 1.25 A Battery tender. Planning to switch to the other battery every 30 days or so. Should have purchased the double bank.
Let me know if I missed anything.
Questions
1) Should I replace block drain bolts/knock sensors now or in the Spring.
2) Indmar manual recommends removing spark plugs and fogging cyliner. Skipped that step.
3) Hurth ZF-45 IV transmission. Did not see any guidance or drain bolts. did I miss something?
4. Oil change at 20 hrs. Seems overkill to change again at 35 hrs. Planning to change at the end of 2016 season. Thoughts?
Finally, I replaced the Port side ballast gate (2nd time this year). I don't keep the button pressed down for more than 2 secs. I am of the opinion, that the Drainmaster CEO should have to replace a ballast gate valve everytime he logs into his computer. Total PIA.
