"I am now in day two of my new exhaust project. I have used two BFH's and a BF Wrench. I am making progress and still have a couple of knuckles left. Someone mentioned stainless steel rods & I ordered them, but the ones that are on there are also stainless. This is the kind of job that makes me wonder how hard can golf actually be? Who am I kidding, I have the disease and am not happy unless I dump all of my disposable income and time into my boat. I'm sure most of you can relate. Anyway... does anyone have an easy way to remove stuck on gaskets? Thanks"

"Wow, I'm just about to plunge into my own exhaust project and am suddenly scared to death. I will be replacing manifolds and risers (raw water cooled in saltwater). They have been on my engines for about 9 years (crudaser 350's)they were professionally done the last time and I am familiar with the company who did them. I feel confident that they used ant-sieze when they put it together, but the stories I have been reading sends shudders down my spine. Any words of wisdom for prep work before starting? Both engines are pretty clean and the bolts seem to be in good condition (except one riser which has a fair amount of rust). By the way I already have a "BFH""

"JB, from what I've heard, anti-sieze is the way to go. You may find that things come apart just fine. However, I would not make dinner reservations just yet. My manifolds came off clean, but they are fresh water cooled. All the raw water cooled parts ended up in little pieces in the dumpster. I wish you the best... ever play golf? :)"

"I only wish I knew how to show a few pictures of the process I had gone thru in doing the FWC manifolds on our engines. I really thought the BFH was bout 5lbs. Ha-ha-ha was that a rude awakening. Well, I said, now I'll have these heads off for Sunday and drop 'em off to the shop Monday. AND, even though I have an extra day each week to do the job( which I did, also being completely frustrated days at a time), Monday came and went 3 times before I got them off with chunks of manifold still stuck to the heads.

Thanks to the efforts of the valve shop, no heli-coils and a great job fly cutting and machining the mating surfaces. As I look through the old elbows, there is NO metal wall separating the two flowing channels. As I shake the canister mufflers, they rattle full of pieces of broken cast chunks of elbow! Since the motor ran great during the process of breakdown, I had no clue this was going on other than the tan mayonaisse accumulating at the hoses going into the flame arrestor.

After this experiance, I may fish from the engine room just so I can keep a close eye on things

Ayuh,.....

BFHs start at 10lbs.,+ Go Up from there....

My Favorite is 20lbs.....
Big enough to do Serious Damage,+ Small enough to still be able to Swing it......"

"That's a great idea Al, I should document this with some pictures. It's not likely I'll be taking on a project like this again. I've been doing the heavy swinging with a 16lb. BFH, but then use a 5lb.er and a coal chisel to get surgical on it. I also found it easier to smash the riser off first, then remove the manifold and take it outside where you can to battle with it on your terms."

"Is'nt this amazing. To have to use this type of approach to do this job.
Since that digital camera, I can take 4096 pictures with the 4gb chip. I probably took 900 of the boat projects so far. The nice part is that you can detail the job for re-assembly IF you get lost. Or just paint yourself a wake up picture for next time.
