    Acid flush on boat motor

    You saltwater guys ever have this done for overheating problems if your motors got a lot of corrosion in it?

    Already did, replaced with new and put new impeller in it. Oiler has been using oil so I'm pretty sure that's a sign the engine is getting oil. When I changed thermostat I saw lots of 'scaling' in there. The boat dealer I just dropped it off at suggested doing a acid flush on it

    Never heard of it and never done it on any of my saltwater motors.

    This is good advise. About $80 and the thing that takes the most time is drilling the hole and routing the wire/tubes. Easy.

    While you have the boat at the dealer for the acid flush, get some mud grip tires put on the trailer. It will give you more traction at the ramp.

    Yes, acid flush is real if you are mainly running the Laguna Madre.

    I used to hold the buildup at bay by pulling the thermostat cap once or twice a year and pouring CLR into the water port. I also used to flush with Saltaway, but not sure if that really did anything.

    It cleared out whatever was in there I guess cause I never had another problem all weekend. Except my tilt/trim switch went out in the throttle and blew out a trailer tire on the way back. I guess I've never seen just how much work goes into a boat cause my Dads always had it all done by himself before we go. I see now they're a major PITA and right up there with maintaining a stock car. Not to mention I've been fishing out of his offshore boat for the last 6-8 years I forget how rough of a ride a lil bay boat can be. I feel broken today...

    It's not really a bay boat.

    Once you get the bugs worked out and use it regularly the upkeep is minimal.
