How Long can in inboard sit Saltwater before it needs to be cleaned out

Working on my trailer and need to moor my inboard BR for three weeks possibly a month in saltwater.
1) How much damage if any am I looking at?
2) If I were to stay at a Hotel for a week and the boat is moored in saltwater
can you please advise what I am looking at in that time frame?


Thank you,
G

I donít know what a BR is, but if itís a heat exchanger cooled engine with shaft drive, and youíve got anodes on the underwater metals, you can sit for a very long time.

Our sailboat with an inboard diesel and shaft drive has been in the salt water typically 3-5 years between hauls for new bottom paint. Anodes are changed while afloat 1-2 times per year.

Hi Smokey,
Thank you for your reply, BR Bow Rider - ski boat- 350 chevy inboard
Older Sea Ray Seville

I notice that folks go to catalina island etc stay for a week or more then return.
Never heard about Anodes so thank you for that I am checking on exactly what that is in pertaining to my boat and how to install.

What youíll notice more than any type of corrosion to the wetted metals is the amount of growth youíll see on the hull/prop/rudder from a week stationary.

Use the boat daily and itíll not get too bad, but let it sit for a week and youíll have slime at the least.

Thank you again,
maybe a tuff job but if I have to go out on the water at least once a week how terrible


The only place I found to place an anode is in the bottom part of the heat exchanger so I would imagine that as long as it is in the path of the water flow it is good.
Thank you again as I never heard or thought of doing this, truly appreciate the information

Re: How Long can in inboard sit Saltwater before it needs to be cleaned out

Welcome to the forum.

In addition to the previously listed bottom growth beginning, the listed mooring storage will not permit flushing the raw water circuit w/ fresh water, to limit internal corrosion.

It probably won't be horrible for that short period, but returning to normal flushing, perhaps even with Salt Away, would be good to implement once possible.

The outdrive should have anodes, material selected for salt water or for fresh water operation. Those sacrifice themselves to protect the important / expensive metal.

Re: How Long can in inboard sit Saltwater before it needs to be cleaned out

So, you have an IO (inboard outboard). Generally, IOs do not like to sit in seawater. I had an old Searay 21' cuddy cabin a number of years ago, I always kept her in a boatel, or on a trailer. That said, a week in the water shouldn't really hurt it, but I would run the engine everyday to help prevent fouling of the prop. Also, exercise the engine mount lift daily, they can get badly fouled sitting in seawater. You should be OK, give her a good fresh water cleaning when you get back.

Good grief. It see it boards left in salt water for years on end with no damage. Think of commercial fishermen and other watermen who use their boats daily.

Go to the Bahamas and Caribbean and other places that have real workboats with poor owners.

I believe the OP has an IO, not an inboard- different animal. The biggest problem people have with those boats is the leg. That leg is not designed to sit in salt water.

True.

If the OP has an IO thatís a different kettle of fish. Still not a huge issue for a week, but more stuff to get gummed up in a week.

Thank you all for your replies, it is appreciated.
I will run the boat at a min. every other day taking it out during that time period.
The trailer is going to take approx 2-3 weeks to complete.
I will post the results so maybe a new thread line can be started.
Again thank you all for your replies.
