Trying to repair a 1987 Evinrude 70 vro (E70TLCUR)
Backstory:
I bought a 16' boat ('80 Four Winns Marquise 170) that included a 1987 Evinrude 70 vro motor for $600. The previous owner of the boat had purchased it to take the 90 hp evinrude motor off and use it on his pontoon boat. This 70 hp motor was on the pontoon boat before it overheated.
That's pretty much all the information I have as to why the 70 won't run. (He said it was running, but not good, thinking that perhaps the water flow stopped due to a bad water pump). He also said that there was water on a spark plug when he removed one of them.
I purchased, and have installed, the following parts:
Water Pump kit
Head Gasket
Thermostat
T'stat Cover Gasket
In-line Fuel Filter
Spark Plugs
Fuel hose connector (motor end)
Gear Oil (lower)
Cap and gasket for Primer Solenoid (Valve was broken, unable to rotate)
Cranking the motor I don't see any fuel getting to any of the 3 cylinders, and there does not seem to be a spark at any of the plugs.
I am testing the motor using a 5 gal. fuel can with 50:1 mixed fuel, new 3/8 fuel line, existing primer bulb. I verified that I have fuel at the output of the in-line fuel filter, but I don't believe that the pump is working. There is not any fuel coming out of the cylinders with the plugs removed and cranking over. No odor of fuel, either, at the spark plug holes.
There does not seem to be a spark at either of the 3 plugs when connected and grounded to the block and motor cranking.
Could I have a bad fuel pump (vro type) and a bad power pack, as well? Could the stator have melted open? I don't know how hot the motor was when it "quit".
The head gasket was definitely bad. There was a breach of the gasket between cyl 1 and 2 where water would definitely enter the cyls.
The metal rings in the gasket were broken in that area and missing some material that would seem to have gone into cylinder 2. There was scoring where the metal bits may have done some damage to #2 cylinder/piston/and probably rings.
No compression test. I wanted to get 'er fired up. I'd imagine cylinder 2 may be low.
Again, no fuel, no spark. Some fuel leaked out of the Primer Solenoid head when I rotated it. The valve is strangely loose.
I have purchased a 1987 Evinrude 65-70 manual and a Seloc 1308.
Time to ask for help! The setting is a driveway job. I don't have a garage. I have experience as a machine mechanic/technician/mill right in precision metal manufacturing and food processing and packaging equipment, but not trained as a engine mechanic.
