'85 Johnson 70 VRO (Deleted) CJ70ELCOS. The motor has been used in the chuck (salt water) from new and had been stored for the past 3 years. Properly stored I should add, in that it was flushed regularly and fogged etc when layed up. It did sit out on the mooring buoy through the summer months, but was always stored properly. It has been permanently "retired" to fresh water use only from now on but on the first trip out after replacing the plugs, ign wires and waterpump and fresh Hi Vis gear oil she emits a fair amount of steam through the exhaust ports at the top of the leg after running flat out. There is water coming out as well, in what I would consider a normal amount: kinda like a mild to moderate "spittle" at idle. The steam lessens a bit after idling and it is not overheating at all and she seems to be running fine. I just do not recall seeing quite that much steam coming out before. Not extraordinary amounts but enough to notice, even from a distance.
Could it be that the water passages are a bit blocked with salt and maybe has some hot-spots? Or is this a sign of a potentially blown head gasket? The plugs all look the same: Dark brownish to tan in colour with a bit of black which is normal really and like I said she spins up smartly and idles steady with no signs of anything out of the ordinary. I did not replace the thermostat but it is clearly opening and closing as it should with the temps at ~190F, max, on my infra-red thermo when running hard and ~130 or so at idle.
Cheers!
