I did buy this boat. Seatrial revealed engines made 2680 according to system view. At 2200 rpm 29.5 according to system view. Sorry but surveyor did not note individually. So im guessing approx 14.8 each. Bottom was fairly clean, 6 on board, 250 gal diesel. So no doubt overpropped. Ive been doing a lot of updating and detailing and put on a fresh coat of bottom paint and had an inch of pitch taken out. Had not been running the boat. Have been waiting for a local diesel guy who keeps postponing.Here are some numbers at the new pitch with about the same load aboard.
1000 rpm 1.5, 1.8
1500 rpm 5.0, 5.0
1700 rpm 7.3, 6.8
1900 rpm 8.9, 8.1
2000 rpm 10.5, 10.3
2100 12.1, 12.1
2200 13.2, 13.7
I did not go higher even though everything seemed good. I was en route to a mini vacation and didnt want increased risk. Have this infamouse drop issue in mind. Ill run her up on the way home in a few days. My guess is the numbers will also be good and will hit 2650+.
I finally have a Cummins guy ready to do the salt side service on exchangers, aftercoolers, gear coolers and change out the heads. So now Im wondering if I really need to spend 11K for the head work portion ???
Quick review: 350 hours, some darkening on tubes, turbo and a little on the aftercooler hot side. Some photos are posted a couple steps back on this thread. Im quite happy running 2000-2200 rpm (18-22 mph).
I would like to hear an opinion on this. Wish I had a crystal ball.
