Could be the insides of your manifold is shot.

Here is a thread on new manifolds.  They are pretty easy to pull off and you can inspect, but after 16 years pretty good chance they are.  I had the welded spots where they seal up the casting go out on mine, and had to have those spots replaced and rewelded, but the insides o f the manifolds were still ok.

I recall that the early catalyst models had an issue with that, especially when listed (leaned) to create a surf wave.  Indmar may have a replumb kit to provide better crossover flow to keep both manifolds cool.

I removed the filter cartridge from the manifold and I probably corrected my problem that the combustion did not come out of the manifold enough, which creates a lot of heat and my engine starts better since then too

That wasn't a filter, it was the catalyst.  If it were mine, I'd probably remove the other side as well.
