Temp readings OK?

[smithrock]

'85 Mercruiser V6 4.3L
Temps reading taken with infared gun:
At T-stat housing -136
At heat sensor - 143
At heat riser - 118
At exhaust bellows - 188+

Are these close to normal. The rubber exhaust bellow temp seems really high. I don't remember them being that hot before. Also I have some steam out of the exhaust ports along with the water. I've never had that before (steam) Any of this stuff normal?

Way to hot...
Not enough water coming through the riser to cool the exhaust gasses.

Any remedy? When I took that reading it was on muffs at about 1500-1600 rpm's I took a reading an hour later at idle and it was around 118*-130* Maybe it wasn't getting enough water on the muffs?
