Checking Fluid Levels w/on Trailer

[AKBASSKING]

My 300DB is on a trailer. How should the trailer be positioned to properly check the engine oil and tranny fluid?

1. Level,
2. Bow High
3. Bow low

Like it sits in the water, bow slightly elevated.

I don't know for sure but I would think pretty much level. They are basicly automotive engines and thats how you check those.

My 240 SD lives on a trailer so I understand your issue. I do all of my maintenance while on the trailer. I do have the advantage of keeping the boat & trailer inside in warehouse.

The trick to checking fluids on the trailer is to have the boat level as it sits in the water. In my case, I know the concrete warehouse floor is level - so I measure vertically floor to stern waterline then floor to bow waterline - I get those measurements the same and I know I'm equal to "floating" conditions.:grin:

If you can't find level ground, have someone hold a long level along the waterline in the center of the boat while you adjust the trailer tongue to "level" the boat.:grin:
