Another Manifold/Riser Question-gctid381214

[Guest]

I am probably going to take a pounding for this, but I did a search and read more manifold/riser threads than I can remember and did not find the answer to this question so I :surr. Does a boat need to be out of the water to change the manifolds and risers or can it be done at the dock? Sorry for such a dumb question.

It all depends of they are above or below the waterline. Mine are above.

Depends on the boat. Just a suggestion: If you could give more specific info about your boat you could get more meaningful answers. Inboard, outboard, seacocks, etc.?

They should be well above the waterline otherwise water would get into your engine.

I stripped my engine 7.4 in a 2859 down including the heads in the water.

You can usually see the water part way up the Y pipe when you remove the rubber couplers.

This is a bad picture as you will note antifreeze in the block, but this was taken after we pulled the boat because the engine had to come out.

Sorry :worth, did not have time to type out a long winded post. I have a 2252 ciera classic with a 5.0 raw water cooled engine and no sea cocks that I know of.

You should be OK to change out while in teh water. That Y pipe is pretty high above the water line!
