Great video. Do you know whether the engine was fresh water flushed regularly? I'm wondering if it would have made a difference with the corrosion around the water pump.

[@sloth-worx]

Thank you. Both engines are flushed after every use but the boat sits in the water 24/7 so getting a good flush like in a sling or on a trailer is impossible. With that said it’s pretty common to see a bit of corrosion in that area if you run in the saltwater even being flushed on a trailer because the gasket seems to absorb or hold onto a certain amount of salt and there is a lot of dissimilar metals going on there as well. It’s usually not a problem and seems to stop or slow down when the gaskets and bolts are greased. Pulling the lower unit and greasing the water pump gasket and bolts before the outboard ever hits the water helps the most and ensures you will be able to remove the bolts for future maintenance but most people don’t have the time or patience for that.

Are there any grease fittings on the 300?

[@sloth-worx]

No grease fittings on Verado. You can spray some corrosion X or something similar where the engine pivots while steering if you want but I generally don’t mess with it. Thanks for watching and commenting!!

when you installed the lower unit. Do you put everything in neutral?

[@sloth-worx]

Yep. Everything in neutral. Once the lower unit is installed the prop should turn freely. I don’t think I mentioned it in the video but the engine will need to be running on a hose or in the water to verify forward-neutral-reverse are functioning correctly. Thanks for watching!!!
