I found 2 distributors that sell Barr manifolds. InboardOnline.com 877-327-7175 and Seaway Marine 425-412-4006. I will be getting prices from them The Barr P/N is OMC-20-913784

Thanks, Lou, That is a good plan, going with Barr for everything,

New problem. The bolt holes in the exhaust manifolds do not line up with the bolt holes on the risers! I will return the aftermarket risers and look for resers that fit !!

I was wrong. The hoses for the water come into the manifolds at the ends, just like on the original. Both ends have threaded holes to accommodate the port or starboard side. I purchased 2 stainless steel 1 Inch to 3/4 inch threaded/ Barb fittings.

Yes, the starter is not the original and has 2 wires, the larger one similar to a battery cable and a smaller red one going to the starter solenoid. After studying the wiring diagram and reading a few posts here, I was confident enough to crank the motor with the starter. I did spray fogging...

1991 Ford 5.8 Ltr I disconnected a few wires from the assist solenoid in order to gain more access to the valve cover on the starboard side. I thought I had taken enough pictures, but apparently not #@&. I have the OMC shop manual and the wiring diagram; see attached. The reason I'm...

You were right! There is a hose port on the side, about the same place it was on the OEM manifold. Now I just need a fitting to screw into the port that will attach to the hose. Headed to the hardware store now ...

Lou or anyone. I see that you: "First thing I did with my Barr conversion. After I took the paint off, they were just about perfect…" I also have Barr manifolds. I am cleaning off the paint from the mating surfaces. That is a lot of work with a sanding block and a paint scraper!! What did you...

There are a lot of missing snaps, so I'd prefer not to have to sew on a doubler. There should be a strong adhesive that I can use to attach a doubler. Anyone want to make a suggestion?

The boat comes with a very well made cover that snaps onto the boat in many places. A lot of the snaps have torn out of the cover. I'd like to add small doublers and then use my snap kit to add new snaps. I tried using iron on patches but they do not stick to the Sunbrella fablic. Any...

Sounds like you used a generic hose and not one shaped for this application. I could use the existing hose, which would get me 2/3 of the way there and then add a straight section to go the extra 8 inches to the opening, then a 90 deg. fitting going into the manifold. Because the existing hose...

Thanks Lou. Did you have to change the hose from the thermostat housing to the manifolds?

Here is a picture of one of my exhaust manifolds and a Barr manifold I can get tomorrow. See the discussion above about the differences:

I have been able to get the old gaskets off the heads. There is another post on just that. I have located new exhaust manifolds by Barr for a good price. I will go to the shop tomorrow to be sure that they fit. I do know that they only use 4 mounting bolts. Mine has all 8 from left to right...

I was able to get all the gasket material off the engine block. Here was the method: 1) Vacuum all around the exhaust and the spark plug holes 2) Use the vacuum as a blower and blow out any debris 3) Block the exhaust ports with sponges cut to size 4) Block the spark plug holes with tubing and...
