is there a thermostat in the outdrive, it seems as if exhaust is coming from bellows when it is actually coming from lower front section of lower unit. a small amt of cool water comes out of prop.<br />please help
that's normal. there is no stat in that outdrive. however, if it's running hot at high rpm's it sounds like a bad impeller. if u don't know to get at it, post again. it's a relatively easy fix, on omc's.
i checked impeller and housing look good, have been told i may need manifold and riser but dont want to spend that much on a guess. i thought there may be some other obstruction. would like to check/change engine water pump but cant get pulley off of pump<br />wish me luck<br />merf
what year is it? i would pull manifold/riser &check ror rust buildup/ clogged passages. u can also have em pressure tested. if they fail u run the risk of ruining engine, by getting water in oil/hydro lock. pay now or pay a lot more later.
Pull the thermostat housing, there is a hole in the housing app 3/8 inch dia that allows water to enter or exit block. I forget which engine the Ford or GM. The hole fills with rust and water will not circulate thru the block.
Had a similar problem last summer the manifolds and risers were pretty well clogged. A local radiator shop cleaned them in their acid tank for a couple days. Took them home and cleaned them a little better with a wire coat hanger and a screwdriver and they were fine. The shop charged $40.00 I think.
