hello great day out on water

[Tonysca6]

I could only feel envy, not splashing until mid April. We have had great weather the last week and no where to go.

I noticed today that my 44 Ac stereo and speakers are all tied into the 120v system including speakers which are switched on the bridge .. So am I right in thinking if the generator is not running there will be no audio while under way ? I guess there will need to be another 12v stereo installed ??? Thank you...

got me on that one

look like we getting a few more members with the AC Models maybe we can get some more post on new ideas

My wife and I were talking about this same issue this weekend trying to decide whether to leave the Lady in water this winter? did you happen find out any more info regarding the hardtop issue for the bridge? We have decided to leave the boat in water this year, winterize her & since we are totally enclosed decided not to shrink wrap. I will be providing additional support to the bimini in case a heavy show does show up.
I am also amazed that our thread is not all that active? I have not made many modification other than adding a Hurley davit and some cosmetics. Did have to have deisel worked on this pat July, bad overheating problems, they seemed to be resovled. Still not getting to the cruising speeds that you all are getting, maxing out around 18 knots at WOT. Aslo still having soot issues.
Planning to change out our tv's & stereo systems this winter (not working at all). just started changing the lighting to LED, going to use blue in the bridge & cockpit.

Happy boating!

Tony,

What did you determine the over heating problems as I have had to keep ours below 2250 when the water was in the upper 70's this summer. Starboard engine water got up over 200 and I had to pull the engines back to 2250 coming back from the long summer vacation run. Put a small camera into the intake side of the heat exchanger and found some rubber and old zinc's that had accumulated over time. Will be pulling the end cap off both heat exchangers and having the cleaned along with pulling the debris out. It would appear the original owner's had some zinc break off and never had gotten the pieces out. I replaced both raw water pumps last fall as the Starboard side had a small leak and we couldn't fix it. When we replace something on one engine we do the same thing to the other so they stay on the same schedule. I will anyone whom has the 3126 cats in their AC the Port side requires a snake to change out and even then it took two of us to get the new one back in place as there is no room, imagine that.


On another note I have changed all the TV's out over the last couple of years as well as added one to the rear deck so I will take some pictures and post if anyone cares to see them. A couple of other modifications have been done as well so I will take some pictures of them and post next week hopefully. We are about 70 miles as the crow flies from you Tony and we are own the boat year round as we are under a covered roof.

John,
It was a combination of things, we had all the impellers replaced last August (they were shot) and did a flush at our previous marina then the storm hit and did not really have chance to sea trial plus the admiral had an accident and broke her leg. In the spring when we splashed the over heating was persisting and could not run over 1900 rpm for any length of time. Did not trust the previous marina's any further. We took the Lady over to Seven Seas at Mears at the recommedation of our surveyor, Reno Panico. They worked on it for 3 weeks. did an acid flush and found additional rubber & zinc. We also pulled the boat and tuned the props, that all seemed to work. WOT is around 2750 and we also seen it as high as 2900 which is above specs. This is the first boat we have owned and love it, still learning a lot about boating and diesels. Going to try and take a clas on the Cats this winter.
We tried to make down your way last month when we finally got a weeks vacation, we have had brutal year at work, foul weather killed the 1st half and ended up just staying a few days at St Mike's on the hook. Pictures would be great, I also changed out the bar sink and faucet, will try to post. Probably will change out the ice maker, replaced all the hoses, they were cracking left & right, this past weekend it stopped making ice completely. I will need to have all the guages on the starboard side either calibrated or replaced, they are bouncing all over the place.
I know you all are little south of us, we are still debating whether or not to winterize? Any opinions would help. Mears puts bubblers out & was planning to leave the heat pumps operating through the winter & just blow out the water lines. Need to figure that issue out yet. Will also put electric heaters in the bridge, cockpit & engine room. We live in Pittsburgh, our dock mate lives close by and said he would check on our boat, good people.

Your over heating problems could be from the trans cooler check that it plugs easier than the heat exchanger. Pulled mine last year and could not believe how much corrosion was in them. Also changed all TV , removed VCR and Installed DVD, Ungraded GPS, Installed Satellite TV, New floors new props will try to post some pictures
