We acquired a new to us 1994 PS190 that we are going to use for free skiing in saltwater.
I have read about flushing and engine care.
My main question is for people who use their inboard skiboat in saltwater, is it OK to keep our boat floating at the community dock in the water for a weekend / 3-4 days at a time and then rinse and flush it thoroughly when we pull it?

    Do a closed cooling conversion and preferably a full one including manifolds. Salt water, even flushed each time will eat the manifolds in a couple of years. You still need to flush it, but it's the bit thats designed to take it. Also add an anode or two to the boat especially on any aluminium/steel interaction area

    I do not believe there is an effective conversion for full (including exhaust manifold) for your boat. I skied is Salt Water for 15 years, the last 9 or so I had a freshwater cooling kit installed, with issue on the engine. I at first would run fresh water after each use to preserve the exhaust manifolds and I would get 4-5 years out of them, a friend never would run fresh water and would get 4-5 years. I realized I was just wasting time and gas, and every 4 years, I would replace the manifolds (approx $500), much less hassel.

    We used to sell a lot of these. Just install in the line, injects the solution in the water intake to protect the engine and manifolds. Hope this helps! Salt Away SA32M Concentrate Kit with Mixing Unit, Salt Removing Cleanser, 32 Fl. Oz.

    @GSchmid, stated alot of things I forgot that I did. I agree with all, even if not in salt water you should use a file to flatten and take edges off the manifolds before installing. Additionally, I used nevercease on all manifold and riser bolts, on a few occasions I changed to stainless bolts for all. As GSchmid stated if you observer even a small leak, correct it before you have a nightmare of frozen and broken fastener.

    I used to run in salt for 20 plus years before I relocated. If you use WD-40 on metal connections exposed bolts and so forth you will be good. As stated earlier keep your bilge dry and alway flush the motor.
    The biggest issue will be the trailer. If you keep a good wax on the frame and put WD-40 in the channels or the inside of the C channel of the trailer that will help. Expose the trailer to as litter saltwater as possible when loading and unloading and that will help keep the trailer looking good. And hopefully rust free.
