"ok, I ordered the new starter

"ok, I ordered the new starter and am trying to reach under the engine to the invisible bolts. I'm pretty sure they are 9/16 however there is not enough room around them for the socket to fit on tightly. The nose of the starter seems to pass through an opening in a wall before it gets to the teeth. does anyone know a secret way to get to these bolts? Do I have to pull the whole motor just to get to it?

Please help me!!!
1979 mercruiser 140 #1 sn#51544xxx

Thanks in advance,

"If it's that tight, you might have to pull the exhaust manifold off to get access. If it's a 1979, do you know how long it's been since they were replaced? Might be a good time to do that as well."

I have no idea how long its been or where the exhaust manifold is. I just bought this boat in march and have replaced the impeller. I have the manual for it but it doesnt show the motor from a starter point of view as to how things are bolted and such. Is the exhaust manifold the wall that is right next to the starter bolt?

Sorry for my ignorance...

"ok, if I'm reading the book right the exhaust manifold is the big honking square elbow coming off teh top of the engine, but its on teh oposite side from the starter, its not blocking access to it. I'll see if I can post a pic.."

My bad. My boat is a V8 and there is an exhaust manifold on both sides of the engine. I should have looked closer at your post before I responded.

I have the same problem replacing the starter. the bolts are hopelessly frozen and there is no way for me to get down under the engine to work on it except pull the exhaust manifolds from both engines. Yours should be a little easier to get to.

Good luck.
 
"tim, i have the same problem

"tim, i have the same problem w/my v8...is there any gaskets that i would need to replace by pulling exhaust manifold off to get to starter? in the past the starter had to come out the front and the only way to reach bolts was with a air ratchet and a long arm. there has to be an easier way."

Starters are just naturally in an awkward spot on marine engines; down low and near the back. They are just a PITA to get to, and to see what you are doing. There is no reason to not remove the stbd side exhaust manifold to make it a little easier on a V-6 or V-8.

You will need one manifold to head gasket; no big deal. There is no reason to break the riser to manifold joint, except to reduce the weight of the whole assembly. If you do this, MAKE CERTAIN you use a new gasket. Make sure its the same as the orginal. There are three types in use depending on your engine plumbing: full flow, restricted, or blocked.

The elbow and rubber couplers can be a chore to break loose if they have not been off in while, but they will give with a little prying with a screwdriver once the screw clamp bands are off.

Reassembly of the rubber couplers goes much easier with soapy water on all the coupler joints.
Thats about as easy as it is going to get in terms of getting to the starter.

"went thou same thing on broth

"went thou same thing on brothers 140hp io. took 2hrs. to get out ,4hrs get back in . did it by feel and with a mirror. short socket,short 3in extention, long handle flexable ratchet, lay mirro in bilge under starter. that'swhat didn't could only turn ratchet about a 1/4 turn at time , just takes a while butit worked for me"
