Bumping for update.

The Surveyor did the interior survey yesterday and everything looks very very good. Stringers are rock solid and hull is as well. No rot at all.

The haul out and sea trial will be next week (weather not cooperating), so I'm looking forward to that. The Surveyor was shocked at the amazing condition of the boat!

Glad to hear that - lets hope the sea trial goes just as well. :thumbsup:
 
Would these engines have had engine alarms? I didn't hear them when I turned the keys on. If they didn't, could they be added? I know on the new(er) mercruisers, the Thunderbolt module controls the alarm. My family has a 1997 Bayliner 3788 bridge boat with twin Mercruiser 7.4l gassers, and it has alarms. How hard would a retrofit be? I just don't want to be caught "with my pants down" in the event my engine/trans temps starts climbing and/or I start losing oil pressure. Better to have an early warning
 
They should already have alarms on them.

Next time, leave the key on for about 5-10 seconds, my alarm does not come on until after a few seconds.

I am thinking the 1984 does not have alarms :smt017 - our 1985 270Da does not have them.
 
Bumping for update!

Well...the big day finally came for the haul-out and sea trial. The surveyor was present and took several GPS speed readings. Both engines pulled hard all the way up to approximately 4400 rpm at WOT at around 33mph (with terrible trim and a dirty bottom).So I'll take that.

Gauges looked normal UNTIL the port engine idled.

At idle, the port engine gauge was 3/4 of the way up! Revving the port engine brought it right down. It was steaming more than the starboard engine out the exhaust.

After the marina splashed it again off a trailer, BOTH engines promptly overheated. At that point, there was NO water whatsoever out the exhaust.

So...the marina owner/broker is getting his lead mechanic to take a look at both engines and figure out what went wrong and fix it. I'm betting something got sucked up and burned up the water pump impellers or got lodged in one of the coolers.

Engines are raw water cooled (but that may change).

Also, that overheating episode showed that it does have engine alarms that work!

What do you guys think?

The haul-out showed a bottom that was in dire need of bottom paint (which I figured), but only 3 blisters on the side of the hull that were dime sized and hard. I can live with that. I've heard it said that there are two kinds of boats, the kind that have blisters and the kind that are going to have blisters. Not sure that's true, but I've also heard that blisters are usually more of a cosmetic thing than a structural thing.
 
Hopefully the overheating is something simple like impellers.
Keep us posted on what the broker/mechanic tells you they fixed.
 
not if they were shut down quickly,sounds like the impellars went since it was just run earlier did anyone shut the through hull off when the boat was pulled,mabey the surveyor to see if they functioned properly,it can happen to the best of us.I was cleaning my bilge last year and needed a place to set a bucket,closed the seacock on starboard engine and forgot to open it,i wont let that happen again $80 bucks for an impellar,and another mess to clean up.The alarms are set to go off before damage can occur.
 
We did not close the seacocks. My guess is that we stirred up some stuff on the bottom that got sucked in and is now in the oil or transmission coolers or the raw water pumps lost prime (I've seen that happen before also).

I should also mention that these engines do not have sea strainers. I would imagine those would be a good investment.

I am also planning to convert the engines to FWC
 
Time for another update:

The mechanic confirmed that both impellers failed causing the mild overheat condition we experienced. They are working on it now and will have it fixed by Friday, at which point I will go on another check ride to verify all is well, and then the deal will move forward.
 
Next to last update:

Sea trialed the boat again and it ran perfectly! Planes out at 3200 rpm and has a nice fast cruise at 35-3600rpm which is just shy of kicking in the 4-barrels. Or you can idle along at around 1600 rpm. Any more than that and the bow starts to lift.

All it needs at this point is new bottom paint!
As soon as next week gets here, it's mine! Be on the lookout for lots of pics!

Final update: It's mine! Went up there today and paid for it and drove it around a bit. Man alive it's fast even at 3200 rpm! It also handles like a dream in close quarters!

Pics to come soon!
 
Ok! Congrats! Now pics are required or it didn't happen...:grin:
 
Nice boat!
 
Thanks a lot guys! Took it on about a 1 1/2hr cruise at at about 3000 rpm and the boat performed perfectly! That is one of the nicest riding boats I've ever been on. Very fuel efficient as well with the 2 mercruiser 260 inboards.

My next project will be installing a new battery charger to replace the one in there that apparently died some time ago and was disconnected by the PO. I think I'm going to get either a MasterVolt charger or another one that is built in, and put it on its own breaker instead of being on the outlets breaker. Not sure why it was done that way to begin with, but I think it came that way from the factory. I just don't like having multiple items on the same breaker.
 
Congrat's - It is an amazing looking boat. I'm a big fan of midship engines even though it cuts down the available interior cabin space. It usually makes for a great handling boat with great weight distribution. Enjoy!
