here are some pics of my boat and me at work (I was working next to a marina) My new engines have 4 inch exhaust and the old had 3 inch so after 2 weeks of messing around trying to get reducers I just built a new 4 inch set up, how does it look? anyone know where the parts bolt to on my engines? (3 pics) and also the dreaded zebra mussels I found in the muffler. Thats it for now , back to play with the boat

Wow those zebra mussels are amazing. Looks like you had plenty of them and it is my guess that they were having an impact on your performance.
Glad you found them when you did.
Good to see a photo of you on the job Dave.

Exhaust looks great, Dave. Must be nice to be able to do that kind of work.
Nice TriFly. Make sure you let that kid drive.
..... and don't fall off any of those roofs.

You said that the mussels were in the muffler, but the pics appear to show them in the hoses (and the box)... where were they really attached, if hoses was it between engine and muffler or muffler and thru-hull, how strongly were they adhered, and how long has the boat been out of the water?

picture 3 and four of the mussels show where they were in the muffler, the first pic shows them in the pipe between muffler and through hull, the boat was out of the water for four years and the mussels were not adhered. The pics are of the port exhaust, when I looked at the starboard there did not seem to be any in it but when I started up the engine on Sunday, the parking lot has bits of zebra mussel on the ground behind that engine

I guess after 4 years out of the water they should be dried out enough that they would come off easily. You can probably scrape / blow the system fairly clean a this point.
They only grow under water, so if you found some lining the hose between muffler and transom it looks like that exhaust has either had a low point in it (lower than muffler and transom port, letting the water pool a LOT), or spent a lot of time under water for some reason.
Question to the other tri-fly owners out there - is your exhaust normally above waterline, or under water?
If the exhaust is normally high and dry, and stays that way once you launch, the hoses shouldn't re-clog (as long as you don't have a dip in the system).
