Trying to replace risers and manifolds on my 90 242ss. The manifold bolts are tough to get to because there isn’t much side clearance. Some of the bolts I can’t get a socket on because they are crusty but there isn’t any room to tap a socket onto the bolts. Looking to see if anyone has any tips. Really don’t want to pull the motor. I’ve gotten 5 bolts out so far but those were the ones with clean heads on them. Thanks in advance

Just doing stock replacements. Didn’t know when they were done last and I’m hoping I got to it in the nick of time saw some rust in both and some moisture in the heads so want to get it back together flush the oil and get it winterized

I was thinking about if I had to I’d possibly do that but hoping to figure it out in the boat. Hopefully can work on it this weekend and put it away until spring

In some cases I have been forced to grind the bolt head off with a burr, then remove the bolt after the exhaust is off. Try heat and penetrating oil first and if possible, beat a socket that is too small ( may need to be metric) on the head. There isn’t much room to work so go slow and use a mirror. I went through all of this after I bought my boat, it’s a real good time. Best of luck.

I didn’t remove the batteries as all the rear bolts came out easy. I haven’t removed the “cabinetry” as it was starting to get dark out but that may definitely help being able to lay down. Basically all the bolts that have come out came out pretty easy and all had never seize on them. Biggest issue is the crustiness on the heads of the bolts and not having room to tap a socket onto them. I will let you know how I make out after getting a chance to work on it again. Hopefully get some decent weather to work on it too
