1976 Evinude 9.9

[superflydudebike]

I went to look at this motor last night. It seemed to have some issues and I did not make an offer on it, but I am wondering how serious the problems may be. It started easily, but I noticed the the propeller spun while in neutral, slowly at idle, but it increased as the RPMs were increased. Clutch dog on this model? Also, there was absolutley no water coming out of pump. This model has water coming out of exhaust area, correct? He said that he hadn't noticed it and he had been running the motor like this. This could cause some serious problems, correct? The flywheel seemed to have fine cracks in it and it started w/o much effort (compression probs?). The other issue was poor ability to idle w/o cutting out. Stay away from this motor or it worth repairing if I can get it really cheap? I doubt this guy ever changed the gear oil, etc. He was rather young and when I was there, he was in the process of having folks over to party.

The spinning prop is normal. That's just the lube turning the prop w/ no load. It won't turn at all if it's in the water.

W/ no tell-tale it can be hard to tell if the water pump is working properly. Put your hand behind the upper exhaust relief (just under the upper cowl on the midsection) it should spit a little.

Cracks in the flywheel, now that's unusual. You sure they're really cracks and not just casting marks?

Bad idle could be electrical, carb, or powerhead. Did you do a compression check? What were the numbers?

Did you check the lower unit for water intrusion?

I'd look at compression numbers, and water intrusion in the LU as the litmus test for purchase on this one. If those pass, every other issue is pretty pedestrian and fairly cheap.

I ran it in a garbage can full of water, so the pump should be working, correct? There was nothing at all coming out. The prop was actually churning up the water then it was in neutal and the engine was revved up. This seems abnormal to me.

Yeah, that is not normal. Probably a shift linkage adjustment. A bad clutch dog will cause the opposite effect - slipping out of gear.

If nothing is coming out the upper hole it still might be okay. I've had a couple with totally carboned over relief holes. However, it's not a condition I would willingly take a risk on unless the price was right.

Does the motor overheat at all if you run it for a long time (15 mins or so)?


Regardless, the compression and LU inspection are the two most important things to look at. Behind that is inspection of the spark plugs - good toasty brown color. After that, a spark check.

Re: 1976 Evinude 9.9

I don't think I had it running that long, but it did not seem to be heating up abnormally fast. The upper shaft area became warm, but not hot. What would be a fair price for a motor like this? Did not do compression check, nor did I check lower gearcase.

Re: 1976 Evinude 9.9

If the compression numbers are good.

If the lu is sealed up.

If you've got good spark.

If the water pump is working correctly (check for overheat - put your hand on the powerhead after 15 mins. Count one, two, three, ouch! If you can't make it that far it's not working properly)

and

If it shifts normally


Motors like that around here will go from $400-$800 depending on physical condition, salt or no salt, etc.


We already know it doesn't shift normally, but it _appears_ to be a linkage adjustment. Simple repair, but i'd go down at least $100 based on that risk. You need to verify the rest of the assumptions though.

He is attemptign to sell his 12' boat (fair), trailer (poor), and this motor as a package deal. I only am interested in the motor. He is now asking me if he is unable to sell as a unit, will I buy motor for $300. I do not have compression tester. The pull cord is not very hard to pull at all. Could this signal poor compression?

Re: 1976 Evinude 9.9

Those motors are pretty easy to pull start. No data there.

Re: 1976 Evinude 9.9

Below is the reponse that I got from the guy that is selling it. Is this correct information?
******************
Water enters near lower unit at intake ports, into water pump (just above lower unit and midsection junction). Water pump is driven by the spinning drive shaft. Water is pumped up a copper tube to the powerhead. Water circulates through cooling passages in powerhead and exits down through lower leg and out thru the prop hub. A thermostat in the power head regulates the temperature of cooling water through the powerhead.


This makes it seem as though everything is working fine? I have also read that if a thermostat is present in the motor you wont see water coming out of the exaust port below the cowling until the engine gets hot enough for the thermostat to open.

If you are still interested let me know. I am still selling the boat, motor and trailer as one, however.
