I priced a Beta replacement - was around $9K. That's just the
engine and trans. Does not include all the
work to put it into the
boat, modify the mounts, new
exhaust, new prop, new
fuel system, new
wiring, etc... If I paid a
mechanic to do it, I could buy 2
Catalina 30's for the
price of the swap. So it's not worth it to me.
My A4 is getting a bit tired, low
compression in #1, but I think I'll replace it with a Moyer short block - easier and cheaper than going
diesel.
What problem are you having? I'd say a good dx on the problem would be more useful than throwing
parts at it.
Guessing from the list of
parts, you're thinking intermittent fuel problems. Temporarily adding a fuel pressure gauge can help you know if you're keeping the carb filled with gas. If not, go backwards till you find it. (Bad
oil pressure switch to the
fuel pump would be common - can be dx'd by keeping a voltmeter on the
pump and watching it.)
