2001 56 Ocean SS

I have the boat under contract. Survey and sea trial is in two weeks. She has 3406E CATs. Any particular known issues to be aware of on the survey? Also, I cannot find any speed curve or fuel usage with these engines on this model. Owner estimates 25-26 kts at about 60gph at about 1950 rims or 80% load. Does this sound about right? Also, how do the fuel gauges work with two gauges and three tanks? The only obvious cosmetic flaw is a small one. The ceiling mirror in the day head is bleeding through major black lines. Is this common? Finally, do the Cats usually come with block heaters? Thanks from a new forum member.

Thanks. Was the replacement through Ocean or aftermarket through a glass fellow?

Thank you. Any idea on the block heaters? Also, I assume the Ocean has some sort of Y valve for permitted overboard discharge. Correct? One last question for now. I did a quick search for impellers on these engines to make a prophylactic change. Curios why they are4 so much more than the impellers for the Detroits I have owned. Anything special about them?

I still have a question about filling the fuel tanks. I have read the prior posts. When filling each saddle tank from the deck fill, do I assume when the saddle tank sounds full, it has already filled the central tank by gravity? I have been warned not to use a high speed hose to fill the saddle tanks. My guess is it overwhelms the gravity feed function. Would that be correct? Also, it would seem that the list created by filling the saddle tank would require that you go back and top off the first tank filled again after you have filled the other saddle tank. Correct?

Thanks. At sea trial yesterday, port fuel gauge showed empty and starboard fuel gauge showed half full. Not too sure what that means as far as expected gallonage on first fuel up.

Thanks.

Just took delivery. I am having a real problem with spongy steering. The fluid level appears to be full. Is there any way to tell whether it is in the head or not. All appears normal at the tiller arm. But, I need to make too many turns of the wheel to get it to responsive, especially if I have been hard over. I guess I may just need to try to bleed it but hoping for some wisdom here. Thanks.

Thanks. That may be the best place to start. Is there any way to tell whether it is the ram or the head?

Another issue. My AC pump runs even when breakers to all of my AC units are off. Any ideas? Perhaps a bad triac?

The pump can be shut off by the AC pump breaker. The problem is that it should not be running at all when the breakers to the AC units are off. Although I am not sure where to look, my guess is a relay or triac is shot but I have no idea where to look for it.
