Am having a grand time following your
rebuild. Did the same thing on our former boat, a
Peterson 44. One poster here said that a benefit is that you know your boat and systems inside and out...totally agree. Regards your low
RPM problem, I don't know if you have sorted that out yet but I also have a
perkins 6-354 on my present boat. A
cheap (er, ah, inexpensive) diagnostic is to take the boat out for a run with no air filter. I have learned that sometimes, air flow problems (is there any black smoke and/or unburnt
fuel coming from the
exhaust when you rev it under load?) that are very
cheap (there I go again) to fix are frequently misdiagnosed as
fuel flow problems and many many dollars (as in, not cheap) of
fuel pump rebuild,
lift pump rebuild, tank cleanout, fuel line replacement bla bla bla later, it was a simple matter of not enouigh air flow to mix with the fuel at higher revs under load. I should also have asked whether you can get the revs up over 2000 in neutral. Airflow problems don't usually manifest themselves when not under load of churning
propeller while the boat is moving (putting it in
gear at the
dock and opening throttle will not allow even a properly air and fuel flowed
engine to get up on her revs). Anyway, just my "2 cents".....keep up the great work.

PS. I have probably gone through 2000 pounds of butyl tape (bedding compound) in removing then re-bedding
deck hardware, hatches, stanchions etc over the
ownership of the 5 boats we have had the pleasure of
buying "inexpensively" so I know some of your pain/joy.
