So I did a booboo and installed some waterlines backwards on the fresh water impeller pump. I had the IN/OUT water lines reversed after servicing. and didn't know it until AFTER I back into the lake first trip this year and start the engine.
2000 Moomba Outback
Indmar Assault 'GM/Chevy' 5.7L carb'd 325HP
First time in/year I like to let the engine warm a bit for a couple minutes - This year I noticed some extra noises coming from the impeller/pump due to it being run completely dry and with the water lines hooked up in-reverse. I also noticed some smells of burnt rubber probably also from the impeller, maybe from the exhaust heat.
I ran the engine for maybe 4 minutes total before I had really realized the fault but I do not think it overheated.
SO, my impeller pump completely lost all of it's squeegee fingers, and they are literally no where to be found.
Being the boat is 17 years old (but with only 250 hours); I figure its a great time to:
1. Replace the impeller and seals (duh)
2. Replace the engine's main water pump with new gaskets & sealer
3. Replace the thermostat with new gaskets & sealer
4. Replace a weak looking main water hose on the engine - main water pump intake side
5. Take off the upper exhaust housings and replace the square gasket / check for any rubber fingers (One of the gaskets had a very slow drip/leak last year anyway)
The boat is equipped with a heater.
I was thinking of running the garden hose through any hose AND the heater forwards and backwards to flush and back-flush anything I could. I feel if anything - the impeller parts are either somewhere between the hull's pickup and fresh water pump | stuck up in the engine water pump | stuck around the thermostat | Stuck in the upper/rear exhaust manifold | stuck in the heater | or stuck at the bottom of the lake.
Next time I'm planning to test start using a fake-a-lake engine flusher first.
Is there a filter/strainer or some kind of catch anywhere I may be missing?
