Replacing Yamaha 3.3L F225 Thermostats - Marine Tech - Vlog#10

[@blondestrainger]

Thanks for the complete video. My 225 is ready for the same. I try to replace stats every three or four years with impellers .

At that level of corrosion, I'd scope the exhaust on those. They are known to fail and leak. Normally when they fail, you can see water coming out the above water exhaust port

You might want to put together a preventive maintenance schedule boats need heavy maintenance on a regular basis not just when things go bad

Mine had had a pin hole from corrosion in the block above the thermostat, under the fly wheel. Seems to be a common problem with these. You should have pulled the zincs in the heads by the spark plugs while you had the thermostats out and flushed it with salt remover. Those zincs have probably never been replaced.

Does the hole or white dot have to be facing upwards?
