The boat all of a sudden has an issue, when it used to do 14 knots 2 months ago. This points to something being wrong with either the engines,...
715hp C12's are 2300 rpm motors, you don't cruise them there. I don't think they make nearly 2300 rpms. In a heavy boat with borderline power,...
They should be 2300 rpms WOT. So how are they making enough power if they only hit 2200 rpms?
Nowadays a lot more than in the past. About half of the yachts I manage require an insurance survey every 3 years. But most of the owners of the...
First, if Fire is your concern, I'd make sure your automatic fire system is inspected and automatic shutdowns tested annually as required by...
There isn't a door there for storage and to slide the unit in and out? Every sportfish I've been on has one, including the Oceans I've managed...
I know exactly what I am talking about and know plenty about hook and rocker. A lot of smaller boat builders built boats with a hook in the hull,...
You should EASILY be able to see that by opening the engine room hatch and looking. If you are having the fuel polished, have everything put in...
I have PLENTY of experience with it, but there is LOTS of very ill handling quarks that could be introduced by doing it (adding hook or rocker),...
CSKIP- also try it with the trim tabs centered and see if that makes a difference. Do you really think an owner is going to re-design the bottom...
I've skinned this cat several times. 1. R417 is about 20% less efficient than R22, that is true. I manage a yacht that had 6- R417 self...
What do you think the lift expectancy of copper lines and their braised welds is when exposed to almost 400 psi of pressure and salt air? Willing...
Then the alarm monitoring circuit board is bad for the starboard engine or the display at the helm with the alarm lights. Do you have digital...
If you're certain all of the running gear is good, then I'd start looking at the engines and possibly not making as much power. When it's...
Here's some big Sportfish running in the inlet at the White Marlin Open. I particularly like the 75' Jim Smith [MEDIA]
They don't get on plane. I ran a 66' offshore with 1000 hp C-18's and it was the same way. It did do 14.5 knots but HAD to have over 10' of...
I have a 1100 hp MAN common rail boat that when the batteries are going bad or getting weak, it will light all kinds of erroneous engine alarms...
Here in Fort Lauderdale, bars without food, have been closed since April. So I guess they can re-open. Most manufacturers I've heard from are...
I'd leave the bow area alone as I simply don't think it will look good.
It sounds like you have some computer issues going on and you need to get a MAN mechanic to come out and hook up the laptop and verify what is...
