Neat! Congratulations to your boyfriend, and to you for finding him :-)
Almost 23 years ago, in Nov 1990, the riser on my Perkins
4-108 needed replacement. I bought a new exhaust
flange, as mine was in poor condition. Don't remember exactly what it cost, but about $100 seems right.
Then, I took the old riser to a local muffler
shop. There, they welded up a new riser for me, complete with the pipe for water
injection, for a total of $73.50.
I installed the new riser and new flange, and wrapped the whole shebang with exhaust
material (looks like asbestos tape, but I hope it was not).
Here's a pic taken last week:
This new setup has worked very well for me over the years and tens of thousands of sea miles. Hope it lasts awhile longer :-)
PS: The white coat hanger in the pic is my "stop button" for the Perkins
. It, too, has worked well for the past 10 years or so, after I spent a small fortune on a new stop solenoid while in the BVI and had it re-machined to fit (because, you know, replacement parts
NEVER fit right), only to find out that it didn't have enough "ommph" to actually stop the engine
Now, after all these years, I'm thinking about replacing the hanger with a manual stop cable this spring, because somebody gave me a new one.
