I will be winterizing the 2005 25 hp Yamaha 4-stroke on our pontoon soon for winter storage, and the lake marina recommends the following:
1. Change oil
2. Change lower unit oil with new plug seals
3. Remove prop and re-grease splines
4. Grease moving parts/steering cables
5. Remove fuel line run out of gas
6. Flush cooling passages
7. Spray some fogging oil in plug holes
They say every 3-4 seasons to do a larger maintenance of changing the plugs and inspecting/replacing the water pump impeller, and that those things are not needed each year. We bought it used from the marina and it had a full service in the spring (plugs and water pump inspection). My questions are, do you all agree with the maintenance schedule prescribed? Also, they recommend using only Yamalube gear oil and engine oil. At Walmart, the Quicksilver marine engine and gear oil is a lot cheaper, so would those fluids be ok? Is there a big difference? What about the Walmart Super Tech brand marine grease? Thanks guys. This is the first year with the boat, so even though I'm a long time gear head with cars, I'm new to boats!
