omc, 5.7 litre. not sure year or anything but i don't think that will make a difference with the question.
I am trying to replace the starter but one of the bolts on the starter is so close to the inspection plate i can't get any tool on it. i can't take off the inspection plate without taking out the engine. i tried to make a socket skinnier with the grinder but it was too weak to turn the bolt without breaking the socket. so i'm just wondering if they have a tool made just for this, or if anyone knows any other tricks.
thanks in advance.

No special tool, I have sometimes been able to pound a 9/16 socket on the head to remove it. I have SnapOn sockets and they are a little thinner. Then, get new bolts. I know the Volvo and Mercruiser bolts have a 1/2" head, but the aftermarket bolts still use 9/16" head.

hey don, thanks for the reply. the head is a 9/16, i don't think i will have nearly enough room to get a swing in there but i'll have to try. maybe i'll try thinning out another socket too, the last one i think i thinned out too much and it broke. i'll take another look at it tomorrow. i don't understand why they make things like this, they know you are going to have to replace the starter at some point in time why would they make it so you cant get anything on the head of the bolt? oh well if i get it off and put another bolt in i'll try to get one with a 1/2 head if thats possible.

Re: is there a special tool for this

I had the same problem with my 5.7 Crusader. After fooling with it for most of the day I was finally able to bend the inspection plate enough get a decent grip on the bolt with my needle nosed Vise-Grips. It wasn't fun, but I got it loose enough to turn by hand.
The REAL frustration came when that bolt wouldn't come all the way out because the transmission mount was in the way. AAARRRGGGG
I had to block up the tranny and unbolt one side of the mount to get the starter out.

And that, my friends, is why marine technicians cost so much!

One note there arks, he doesn't have a transmission, he has an outdrive, and you can't lift up the "Starter" side of the engine without first removing the outdrive. Otherwise, you could permanently damage the coupler which would take an engine pull and a $300 coupler replacement.

haha thanks for the heads up. luckily there is nothing that close to underneath it, i shouldn't have to lift anything to get the bolt out (if i can get it loose). I think i can get a screwdriver tip between the bolt and the plate maybe i can bend the plate a touch.

Ayuh,.....

Another Option,... Although Still not Easy, is to pull the 6 or 7 bolts,+ drop that shield out....
Then trim about an inch,+ 1/2 off it before you put it back on....

And or when you have starter off, replace bolts with socket head allen bolts. Allen wrenches are great for tight spaces (can use allen bit socket drives or regular allen wrench) Thats what I do in a situation such as this! My 2 cents worth! Never know when U have to replace starter again!

Very bad idea.
You need to buy and use new starter bolts that have the knurling on them to avoid a world of other troubles.

DO NOT do that.
Get the proper starter bolts. They have knurled sections in them to eliminate space between the bolt and the starter housing. With regular bolts you will end up with a broken starter nose, or damaged ring gear and/or bendix.

Re: is there a special tool for this

thanks for the heads up on the starter bolts. if i can bend that plate a little i'll just put the old ones back in. i thought about removing the plate but can't do that without lifting engine due to room restrictions. i'll try to bend it and this way it will be out of the way for good

Take a grinder and make the 9/16 into a 1/2?

yep, the 6 points are for heavy duty, the 12's are thinner.
A craftsman is easier to get. Just make sure it says craftsman not sears-sears is poop.

Don S or Bomar76 please explain the stater bolt idea to me! I thought if a person got the same length and shoulder as the original bolt. I don't see what the defference would. Maybe something I'm not seeing!

It's really simple, starter bolts are special design, not standard bolts. Note the knurling just above the threads. This is to take up some of the extra space in the bolt hole of the starter for alignment with the flywheel.
