True, but I'm assuming they're the same....... hence the IF OP: ask your buddy what size props they have.
If the props on the boat are 50" of pitch, and you're turning 2320 with 2.03:1 gears you currently have 32% prop slip right now, so definately...
What ratio are the gears?
Higher chiller temps, will cause higher head pressure, and higher amps. I usually see 10-15F above ambient water temp on clean chillers.
Azimuts from that era have a tendancy to crack fuel tanks. I know of a few 66's with cracked fuel tanks......check the top of the tank really...
I don't remember. A couple very knowledgable Captains ran the 66' over distances and HATED the way it handled in the ICW (speed). Once in the...
Are you on generator or shorepower? In the U.S. or Bahamas? I'm thinking it might be a seperate issue entirely. You have an occasional voltage...
It's also possible to have a frequency drive going bad. I've had that happen before.
I ran a 66' and a 62'. Neither of which would do over 7.8 knots unless you had over 10' of water under their keel, made traveling the ICW a...
I run 10 micron Racors- 30 micron racors are too large for today's lower sulpher diesel. I've come across 5 different yachts, mostly a few years...
The engines are rated for 2300 rpms WOT, but will turn 2400 rpms before the computer stops them from making more rpms. They're hitting 2310/2320...
Need all of the information from the computers on seatrial to see what's going on: IE fuel pressure, boost pressure, air pressure at air filter,...
I had a generator like that and a tune up helped it quite a bit.......adjusted valves, rebuilt injectors etc. etc.
I've run several Offshores, they have some very interesting handling traits as far as seaworthiness goes.
Tired and can't keep rpm's up with a higher load.
The problem is NOT in the props. The problem is in the engines. You're turning rated RPM, so why on earth are you only seeing 94/96% load. You...
A friend ran a 2001 60' Bertram tuna tower, 3412's and when new it cruised at 33 knots. The speed loss most likely is the bottom. Were there 15...
Is it possible that the chiller set points are too low and causing the freon to freeze in the chiller?
I agree that it sounds like 1 compressor is going bad. But can also be a loose connection on a chiller too, that will make it draw more amps once...
Because it's equivalent of trying to tow your 20' searay with a smart car. It's not built for the job. Some older Searays would be my...
