Finally got the impeller installed and that fixed my problem. It took 1 minute for the water to come out the back of the transom at idle. Is that too long? How long can you actually wait for water out the back with the muffs on before hurting anything? I had good water pressure and a little...
K, sounds good...yeah the water pump looks solid with no stains or weeping out the hole. Just don't get why that hose is full of water entering above that circulating pump. I can blow air back through the water line that comes up from the stern right?
Appreciate the help...got the impeller kit coming. Is it odd with even the muff pressure no water was getting up to thermostat housing with an impeller and housing that looks perfect? How do I know if my circulating pump is working correctly with that water sitting in the hose above it?
Just to clarify....does water from the impeller go strait to the circulating pump or does it feed directly into the top manifold and then it goes to the circulating pump? It looks to me it feeds the manifold first. Can I blow backwards with air now that the bottom end of the stern is off.. I...
Ok that makes sense...i just took it apart so I will order parts and report back. It's odd the muff pressure doesn't get water to everything even with a worn impeller. Should that circulating pump clear that hose since it's full of water? I would think since the hose is above it water in the...
Finally work slowed down and getting back to this. Took the the hose off feeding the manifold at the top of the motor, no water. Checked the impeller and it looked good...no cracks and rubber looks perfect. The fins didn't return straight when I took it out but still had to turn the shaft to...
Thanks for the replies...so I have water up to the manifold on top of the engine. Does this say anything...I should have water coming out the other hoses if it's up to the top manifold right? The water wouldn't get up there if the impeller wasn't working?
Have a 1999 mecrusier 4.3 alpha one . I had the muffs on to do a preseason check and have water up to the manifold on top but nothing out the exhausts. When I squeeze the big hose from the water pump to the manifold on top of motor I here water but nothing is going to the risers. Can it air...
Does anyone know where the breakers or fuses are that control the radio and interior lighting. The speedo, tach, and voltmeter work, and the boat runs.
So I don't have any dash electronics working right now. The boat starts and runs fine. Where is the fuse that controls all this? This all started when the batteries were hooked up wrong on one battery. Brain fart, thinking about something else. No fuse so it melted the bolts on the starter...
I have a hole coming into to my ski cubby that lets stinking water in from.the motor area. This is on a 1999 srarcraft i\o. Should that water be getting in there? Can i seal that shut? What water should be moving forward if any. I saw a little water around my battery too.
The grinding noise it makes when you first engage it in forward or reverse, what is actually going on that makes that noise? Some is normal right? This is on a mercruiser alha one gen 2 hooked to a 4.3 merc carbed. What rpm should the idle be set at ? Mines around 600rpm.
