Ok guys, new to the forums and about equally new to boating. I've fished my whole life, and finally have a boat of my own.
Bought the boat knowing it has motor problems. Got a great deal, so that didn't matter.
The motor is a 35 HP, serial # 6491xxx, which dates it as a 1984 I believe.
Anyway, when I go to start it, it cranks, and cranks, and cranks, but won't start! It's almost like the starter doesn't have enough juice, or the battery is dying. The battery is fine, and I think the starter is too, but it's possible it's not. It sounds like when I go to start my car and the battery barely has enough juice to start it. The difference with my boat is is that it will turn over and turn over, but never fire up. The spark plugs have excellent spark. When the spark plugs are out (and the key is turned), it spins much faster and free-er.
When try to turn the top by hand, it is VERY TIGHT, almost immoveable. My 3 buddies motors (some mercury, some evinrude) spin by hand pretty easily (all between 25 and 40 HP).
Where do I start trying to figure out what is wrong? I am halfway inclined to think the head is warped or something, or the piston is swollen or the piston rod is bent, since it's so tight. The motor has around 115 pounds of compression on it, is this normal?
Just trying to figure out where to start and what to do. Thanks guys in advance for all the help!
