Re: 1991 Formula 242 Stringer & Bulkhead Repairs w/ Many Pics
Quick Update . . .
Replaced Exhaust Tubes
I replaced the exhaust tubes yesterday and took the boat out a couple of times. It seems to like the new tubes better. I did not get a chance to do a good WOT test as the bay was not very flat (2-3 foot chop). I got the engine up to 4200 RPM, but could not really trim it well because we were bouncing around too much. Maybe today will be a little calmer winds and flatter seas.
Interestingly enough the new exhaust tube material was the exact same brand/style as the 20 year old material, even though I did not order it as such. (Trident brand)
Here are a few pictures of the new exhaust tubes installed and a look inside the old ones.
The new ones . . . nice clean blue labels
A look inside the old ones . . . the inner layer of the rubber had torn over the years and was restricting flow, etc.
I was also getting a low-level engine noise previously, which I had posted in the engines forum. That seems to be resolved with the new tubes as well.
