RE: [omc-boats] (no subject)

I haven’t had my 69 Sportsman 155 out this entire summer. Busy at work and
a lake down 14 ft (Texas drought) to blame. Now with the cooler fall
weather upon me, I’d like to do a few things in my driveway. This
discussion regarding the tell-tale stream of water raises a question of my
own.

1. Near the end of the season last year, I noticed, while at idle,
water was spraying up from the stern drive onto the engine cover. I didn’t
have time to do much more than lay over the back and try to see where it was
coming from. It appeared to be coming from a location near the ball gears
and spraying (not a stream) up through the gap. Any ideas?

2. I’d like to replace the impeller this winter. I believe the
general consensus this summer has been to replace the housing as well. I’ve
purchased the Selog manual and am ready to go. What I would appreciate (for
my own peace of mind) is advice regarding the correct part numbers and where
you would recommend I purchase them.

Thanks.

Jeff, my advise to you is to ask any mechanic you propose to use if there is
a water stream out of the sterndrive - if they say no - run away from them
as fast and as far as you can!

Yeah, agreed. But this guy seems legit, has a big shop, boats only, OMC
certified, etc.

Second, always feel the exhaust manifolds - if water is circulating they
will be warm, not hot - and you are ok - if hot, you are not ok.

That is one I will definitely try…..

As to the power loss - the first thing to check is the compression - if any
cylinder is low, say less than 120 psi, you could well have a cracked head -
the most common crack is between the intake and exhaust valves which are
very close together and the crack is usually very thin and hard to see -
usually with this type of crack the engine will run fine when cold and then
lose power as soon as it heats up - so it is best to check compression when
it is hot. Dave

And if it’s a cracked head, that spells new engine, right? Not fixable,
right? (gulp).

Ideal timing for this topic. I am dealing with my hot light coming on
frequently. I have a 155hp Deluxe. I am on my 2nd mechanic now, problem
still not solved. Going for a water test tomorrow with him. Just paid a
bundle to have a new impeller and impeller housing replaced, and it
definitely needed to be done. I just didn’t want to attempt it myself – not
still during the season atleast. So now I have a nice new impeller, and
supposedly a new engine water pump too (according to the 1st mechanic). So
in theory, water should be flowing through the engine just fine. But the
hot light still is coming on, and worse, I have barely any HP at full
throttle. It tops out at about 10 mph. Not good, I know. For some stupid
reason, the temp light was wired by some previous owner so It only comes on
when the instrument lights are turned on. And of course I only discovered
that after several times out. Most of those times it ran great, just
wouldn’t start back up when hot. But the past 3 times it has had this
throttle problem. I am just hoping nothing has been serious damaged.
Anyway – will hopefully know more tomorrow after the water test. But my
main question is this:

I have always had outboards, all of which had a nice easy to see tell tale
stream of water shooting out the side when things were working right. I
asked 2 boat mechanics on separate occasions if stern drives were supposed
to have the same thing, both said no – that outboards do, but i/o’s don’t.
But this post says otherwise. So do they or don’t they? And if not, why
not? How are you supposed to tell if water is circulating properly?

Curt,
If the temp light is on the first thing to check is the stern drive while it
is running - on the starboard side of the drive you should see a steady
stream of water shooting out - if not shut her down - that would mean the
impeller is not pumping at all. Next, if water is coming out open the engine
cover and feel the exhaust manifolds - they should be cool enough to hold
your hand on - if not and they feel really hot when the light is on, then
shut her down - it would likely be the engine water pump, or the thermostat
that needs attention. As to wintering, and I know people will flip at this,
but I have seven OMC's and have had them for years and have always just
opened the petcocks on each side of the block - never bothered taking off
the water pump hoses etc. - just make sure the boat is realatively level and
the block will drain down and you will not have any freezing problems. I
keep an OMC V6 Sportsman on the davits on the back of my houseboat - and I
have used it at 10 below zero - when I lift it back out of the water all I
do is open those two petcocks - the only real problem I have is remembering
to close them when I go for a ride - of course eventually warm water will
creep up to my feet - a sure, but gentle reminder! Dave

Group,
I am a relatively new owner. I have a Sportsman 155 acquired in a cabin
purchase. Its in terrific condition. I'll post pics on the other site
sometime soon.. I have a relatively basic question. The temp light goes on
after a few minutes in the water. Do I need to replace the water pump and
if so, do I need to know anything special to accomplish that. Where do I
get parts? Also, I need to winterize it soon. Could anyone give me some
pointers there too?
Much appreciated,
Curt
