SouthernWake Posted May 27, 2020 Report Share Posted May 27, 2020 With the thermostat out pick out all you can. Then out in a bucket/tub and run with a heavy salt away or descaling mixture and see if that softens/opens it up more. if that doesn’t work you may have to open up the water jackets and clean them out by hand. new thermostats after either.

SCFD rtrd. Posted May 27, 2020 Report Share Posted May 27, 2020 Try using white vinegar to dissolve salt. Careful, it may dull paint if left to dry. Just rinse any run-off with garden hose. Quote Link to comment Share on other sites More sharing options...
Wanaflatsfish Posted May 28, 2020 Report Share Posted May 28, 2020 go to a feed store and get a large horse watering plastic trough...run the engine on muffs with salt away several times...then...in the horse watering station... fill it with water and a gallon of salt away and let it idle for a while....so it gets hot and opens the thermostats and runs for a while.....watch the pee stream to insure tt doesn't over heat....you will feel it..... Note, the through has to be deep enough to cover the entire lower unit, not just the intake port to allow it to create a good pee stream. I run my 1996 yamaha 115 two smoker every week in fresh water horse drinking station....keeps the gas fresh and no build up in the carbs.

brudnlaw65 Posted June 1, 2020 Author Report Share Posted June 1, 2020 Thank you for the advice.fixed the problem with a tub of water and CLR submerged the lower unit and run off and on for about 3 hours....flushed out about qt of salt/shell mix replaced with new thermostats all seems well. 1 Quote Link to comment Share on other sites More sharing options...
polliwog Posted June 1, 2020 Report Share Posted June 1, 2020 Good that it is ok, I will never understand why anyone with an outboard used in salt water doesn't flush the engine. Any boat kept in the water at a slip needs to be hooked up to a hose p and run for 10 minutes. If you are trailering run the motor on muffs. I have one in the water and one on a trailer, it's simple to do while you clean up the boat. 2 Quote Link to comment Share on other sites More sharing options...
LBass Posted June 8, 2020 Report Share Posted June 8, 2020 How often should you run salt away through the motor? Quote Link to comment Share on other sites More sharing options...

I will sometimes throw in a full gallon of salt away..it bubbles up and I recirc the water by keeping the pee stream in the trough.... the first time I did this I found good bit of sand and crud in the bottom of the trough....now, I just run the motor for 15-20 min (I add fresh water as it gets hot)....while I"m fiddling with the skiff on the trailer.
