Have any luck finding out why your block was hot?

Have any luck finding out why your block was hot?

Thanks those pictures were perfect got the block running and the ground wires that go from the harness to that bolt on the bell housing made it ground. Or possibly could have gotten a bad reading.

Thanks for those pictures!

The engine is running but now I can't get the impeller shaft to rotate. I tried purging the water on the water pump in the engine from all sides on all the hoses but for some odd reason I get no water circulation and the **** on the bottom of the exhaust manifold isn't dripping any water even with the muffs.

I had the same problem with mine but what I did was take the top hose off the thermostat housing and run water in the hose till water came out of the port I took the hose off of then reattached. I also changed the water pump impeller and associated parts in the stern drive because my boat had been sitting for 4 years and with doing thise two things it circulated water.
Now as far as the petcock I had rust buildup at that point so I removed it and opened the port up.
When I installed the new water pump I put a thin film of grease where the impeller contacted the stainless cup it rides in for initial startup. If you need more pictures I can take them tomorrow morning when I get home from work.

Cleaning up the deck surface of the old 4.3 block before installing reman heads.

That looks good, crossing my fingers my head holds up. Check for clearances and I think she is good to go. The reman heads are purchased, or machined?

My impeller is brand new! Thanks for the help, I tried running the water in that top hose until the water from the port side that goes to the intake manifold passed it through.

Does the impeller spin when the lower unit is in neutral ? Mine isn't spinning but I see no reason why it should unless it's in load which would be to draw more water as the boat is moving.

I don't think what I just said makes sense, the impeller should constantly spin so now I think something else is screwed up.

It should spin whenever the motor is running in neutral or any other gear to keep the motor cool just like a car. The shaft is driven from the upper drive (I believe) so if it isn't spinning I would imagine that is where the problem might be.
I'm learning as I go myself but I'm glad I could help
Might also check the pump again just to make sure it wasn't wedged and stripped out.

I tested the impeller by opening the housing and cranking the engine and I couldn't see any sign of rotation on the little metal housing. Sometime this weekend I'll start the boat again and check to see the shaft from the yoke (this is the spline shaft that is driven by the motor from the coupler) I did see some axle grease but I need to look to make sure it is spinning.

The wedge appears to be in new condition I checked this morning before leaving.

I'm very new to this also, first boat

 

[mighern7]

On the positive side I checked to see if the shaft was spinning and it turns out it is!

That's awesome! The black rubber impeller is what will spin not the metal housing.
Did you have your hose on full when on the muffs?

Hose was on full, I think some water should have still been coming out of the exhaust even with just garden hose pressure at the sea water inlet?

Did you use an aftermarket impeller kit? Sometimes the inner slot will spin or slip and the wedge will not turn the impeller. I have always used an OE impeller kit. You can get them on line or from a dealer that sells Evinrude outboards. Next best is Sierra. Avoid GLM. Here the 2 boating supply shops I use won't even order GLM, due to past quality problems.

I did, actually think it's some cheap ebay I have the old impeller which looked fine I will look for it and try to put it back with these newer gaskets. My old one didn't have any gaskets on it just gasket maker and it was kind of old so I replaced it.

Heard some people put some gasket sealer on the surface of the impeller that faces the shaft. Might help temporarily?

Replaced the new rubber impeller back with the old oem one and now I'm getting some nice cooling ...

Everything is rotating as it should.

Changed the oil on the stern drive and found some water. Makes me nervous I probably will not look into it until the engine is buttoned up nicely.

Ok glad you got the impeller working now when you changed the gear oil how did u do it? Did you get about 2 qts in? Checked with the dipstick on the top cover after filling? There is a certain right way to fill these drives that must be followed...or else burnt up upper gears are the result!

I started pulling all 3 oil plugs left it draining while I went to buy the specialty adapter and pump.

1. Filled from the bottom about 3/4 quart until fluid spilled in the middle plug.

2. Closed the middle plug and kept pumping checking fluid at the top with the dipstick. As the fluid approached the dipstick there was 6-8 more pumps until the gear filled to the line.

3. Removed the adapter lost some fluid in the process, the gear oil was at the mark.

Forgot to add that I made sure the top of the stern drive was level.

Which way do I troubleshoot for a water leak into that gear oil? (Dont say cracked stern drive please lol)

Thanks for the reply, you guys are seriously awesome I'm learning a ton on this old boat!

In this link it tells you the OMC way to properly fill the gear oil. Your way MAY work but after it sits make SURE to check the level with the dipstick in the top cover.

leaking testing you have to get a leak tester (pressure and vacuum). If it water leaked in, and you never had it in the water, it could be the seal behind the mount for the impeller. I had that changed on mine once. Did you change the fiber washers for the drain plugs and dipstick? that can cause leaks too but only if you are using it in the water.

I'm glad you got cooling to her sorry I hadn't replied till now have been stuck at work the last two days.

Waited a full day, doesn't seem to have any air bubbles looked like it is still filled to the line.

-It could be the seal behind the impeller, sadly I didn't notice the water until a couple days ago. Last time I checked oil was last year haven't had it in the water since. It was a good amount of clean water! I didn't change the washers but I will do that sometime before I test it.

 

[mighern7]

Bad news! Since the engine sat for a few days I see some moisture in the oil it's a little cloudy.

Head might be effed?!

I'm out of ideas !
